Build and Deploy a Cloud App

CHAPTER 1 INTRODUCTION About the project: The new way of building and running applications are enabled by the world of cloud computing, where we can access applications, over the Internet as utilities, rather than as pieces of software running on your desktop or in the server room. This model is already quite common for consumer apps like email and photo sharing, and for certain business applications, like customer relationship management (CRM). The Force.com platform is the world's first Platform as a Service (PaaS), enabling developers to create and deliver any kind of business application in the cloud, entirely on-demand and without software. It's a breakthrough new concept that is making companies radically more successful by letting them translate their ideas into deployed applications in record time. Building, sharing, and running business applications have never been so easy. Building and running business applications with traditional software has always been too complex, slow, and expensive. A new model, called cloud computing, has emerged over the last decade to address this problem. Applications that run in the cloud are delivered as a service so companies no longer have to buy and maintain hardware and software to run them. Salesforce.com pioneered this model with applications business over the last decade. More recently, Force.com have opened up the infrastructure and made it available for anyone building any business application and running it on the servers using the Force Platform. The Force Platform allows you to store structured data, implement business logic with workflow rules, approval processes and custom code, support Web browsers, integrate with other applications, do reporting and analytics and scale up or down—all with sub second response time, high availability, and security you need to run your mission critical business apps. COMPANY PROFILE: Springboard Competency Development Centre: Springboard provides competency related services to two vital segments of IT community, namely: ,[object Object]

IT organizations that want to recruit high-quality, project-ready engineers. And, they want to reduce time and budget allocated for training Our partner organizations can now outsource their Fresher Induction Program to us. We will put them through either our standard CDP or through a custom-CDP developed exclusively for our partners. Learning Model: Springboard uses a unique learning model called Knowledge-Immerse-Measure (KIM) that helps the participants to reach higher competency standards in a short span of time. This model ensures the participant gets adequate level of knowledge, skills and attitude so as to help him / her to get into the world of professional assignments at ease. 24574506096000 Comprehension Development Model: Many face learning difficulty involving the most basic aspect of technical or on-technical skills. The difficulty lies in the reception, comprehension, or production of quantitative and spatial information. One gains knowledge through context (experiences) and understanding. When one has context, one can weave the various relationships of the experiences.

It is assumed that this application will be developed in the following environment: Force.com environment Visualforce as the developing language lt;br />CHAPTER 2 SYSTEM ANALYSIS Existing system: As users of the Internet, we're all familiar with the fascinating, innovative, creative, and sometimes silly ways in which it has changed how we work and play. From social networking sites to wikis to blogs, and more, it’s exciting to watch the innovations taking place that are changing the ways we communicate and collaborate. While these changes have certainly impacted how we work with content, a similar set of Internet-driven ideas and technologies is changing how we build and work with business applications. While yesterday's business applications required thousands, if not millions, of dollars and sometimes years of professional services help to set up and customize, the technologies offered by the Internet today make it much easier to create, configure, and use business applications of all kinds. Indeed, the power of the Internet has given us the ability to solve new kinds of business problems that, because of complexity or cost, had previously remained out of reach. Just as the changes that moved publishing technology from paper to bits made it possible for us to have information about anything in the whole world right at our fingertips, the changes in application technology make it similarly possible to imagine a robust, enterprise-class application for almost any business need. Sound pretty good? Then you're probably wondering: “What's the magic that makes this possible?” These new ways of building and running applications are enabled by the world of cloud computing, where you access applications, or apps, over the Internet as utilities, rather than as pieces of software running on your desktop or in the server room. This model is already quite common for consumer apps like email and photo sharing, and for certain business applications, like customer relationship management (CRM). Drawbacks of Existing System: By using the existing system we have to maintain a high configuration system to run some huge software’s which is used to develop the applications. This may need huge cost to buy and maintain. We have to buy the each and every software’s which are used for developing the applications. Also we have to update the software’s for latest version. This needs maintenance risks such as economical risk and technical risk. The main disadvantage of the existing system over cloud environment is lack of portability. Even though we are having high configured systems and updated software’s we have to take the system with us when we are moving from one place to other place. This will create risk to the users. The main disadvantage of the existing system is lack of disaster recovery. That means in the case of any disaster occurs all the data available in the system cannot be recovered. Thus it may leads to the loss of data. The existing system also needs high initial out lay to set up the system. Proposed System: Since there are lot of problems available with the existing system a new technology is used in this project called as cloud computing. The proposed system in this project is to develop an application in the cloud computing environment and have to deploy it and to launch the application in cloud. The cloud environment used in this project is called as salesforce environment. A simple application is developed in the cloud environment and deployed in the same environment using the tools provided there itself. The application is launched as a site inside the cloud. The security provided by the platform provider (salesforce) is used in this application. Feasibility study: A feasibility study is an evaluation of a proposal designed to determine the difficulty in carrying out a designated task. Generally, a feasibility study precedes technical development and project implementation. In other words, a feasibility study is an evaluation or analysis of the potential impact of a proposed project. Economic feasibility: Economic analysis is the most frequently used method for evaluating the effectiveness of a new system. More commonly known as cost/benefit analysis, the procedure is to determine the benefits and savings that are expected from a candidate system and compare them with costs. If benefits outweigh costs, then the decision is made to design and implement the system. An entrepreneur must accurately weigh the cost versus benefits before taking an action. Cost Based Study: It is important to identify cost and benefit factors, which can be categorized as follows: 1. Development costs; and 2. Operating costs. This application needs less amount of cost in both development and operating state. Time Based Study: This is an analysis of the time required to achieve a return on investments. This application takes less time to execute and to use. Operational feasibility Is a measure of how well a proposed system solves the problems, and takes advantage of the opportunities identified during scope definition and how it satisfies the requirements identified in the requirements analysis phase of system development. The proposed system solves all the problems in the existing system in the basis of time, cost, risk, Etc,. Technology and system feasibility The assessment is based on an outline design of system requirements in terms of Input, Processes, Output, Fields, Programs, and Procedures. This can be quantified in terms of volumes of data, trends, frequency of updating, etc. in order to estimate whether the new system will perform adequately or not. Technological feasibility is carried out to determine whether the company has the capability, in terms of software, hardware, personnel and expertise, to handle the completion of the project. The usage of this application over cloud environment simply needs a un interrupted internet connection of 512kbps of speed.

The Visualforce framework includes a tag-based mark up language, similar to HTML. In the Visualforce mark up language, each Visualforce tag corresponds to a coarse or fine-grained user interface component, such as a section of a page, a related list, or a field. The behaviour of Visualforce components can either be controlled by the same logic that is used in standard salesforce.com pages, or developers can associate their own logic with a controller class written in Apex. Developers can use Visualforce to create a Visualforce page definition. A page definition consists of two primary elements: • Visualforce mark up • A Visualforce controller Visualforce Markup Visualforce markup consists of Visualforce tags, HTML, JavaScript, or any other Web-enabled code embedded within a single <apex:page> tag. The markup defines the user interface components that should be included on the page, and the way they should appear. Visualforce Controllers A Visualforce controller is a set of instructions that specify what happens when a user interacts with the components specified in associated Visualforce markup, such as when a user clicks a button or link. Controllers also provide access to the data that should be displayed in a page, and can modify component behaviour. A developer can either use a standard controller provided by the Force.com platform, or add custom controller logic with a class written in Apex: • A standard controller consists of the same functionality and logic that is used for a standard Salesforce.com page. For example, if you use the standard Accounts controller, clicking a Save button in a Visualforce page results in the same behaviour as clicking Save on a standard Account edit page. If you use a standard controller on a page and the user doesn't have access to the object, the page will display a insufficient privileges error message. You can avoid this by checking the user's accessibility for an object and displaying components appropriately. • A standard list controller enables you to create Visualforce pages that can display or act on a set of records. Examples of existing Salesforce.com pages that work with a set of records include list pages, related lists, and mass action pages. • A custom controller is a class written in Apex that implements all of a page's logic, without leveraging a standard controller. If you use a custom controller, you can define new navigation elements or behaviours, but you must also reimplement any functionality that was already provided in a standard controller. Like other Apex classes, custom controllers execute entirely in system mode, in which the object and field-level permissions of the current user are ignored. You can specify whether a user can execute methods in a custom controller based on the user's profile. • A controller extension is a class written in Apex that adds to or overrides behaviour in a standard or custom controller. Extensions allow you to leverage the functionality of another controller while adding your own custom logic. Because standard controllers execute in user mode, in which the permissions, field-level security, and sharing rules of the current user are enforced, extending a standard controller allows you to build a Visualforce page that respects user permissions. Although the extension class executes in system mode, the standard controller executes in user mode. As with custom controllers, you can specify whether a user can execute methods in a controller extension based on the user's profile. How is Visualforce Architected? All Visualforce pages run entirely on the Force.com platform, both when a developer creates the page, and when an end user requests a page, as shown in the following architecture diagrams. Visualforce System Architecture - Development Mode When a developer finishes writing a Visualforce page and saves it to the platform, the platform application server attempts to compile the mark up into an abstract set of instructions that can be understood by the Visualforce renderer. If compilation generates errors, the save is aborted and the errors are returned to the developer. Otherwise, the instructions are saved to the metadata repository and sent to the Visualforce renderer. The renderer turns the instructions into HTML and then refreshes the developer's view, thereby providing instantaneous feedback to the developer for whatever changes were made in the mark up. The architecture diagrams below shows the process flow when a non-developer user requests a Visualforce page. Because the page is already compiled into instructions, the application server simply retrieves the page from the metadata repository and sends it to the Visualforce renderer for conversion into HTML. Visualforce System Architecture - Standard User Mode Features of Visualforce: ,[object Object],Developers can edit their Visualforce mark-up in the same window that displays the resulting page. Consequently, developers can instantly verify the result of an edit just by saving their code. The Visualforce editor pane also includes auto-completion and syntax highlighting. Visualforce also supports “quick fixes” that allow developers to create supporting components on the fly. For example, a developer can define a new Visualforce page simply by logging in to Salesforce.com and then entering the name of the new page in a URL. Much like a wiki, if the page does not yet exist, the platform creates it for you. ,[object Object],Because Visualforce mark-up is ultimately rendered into HTML, designers can use Visualforce tags alongside standard HTML, JavaScript, Flash, or any other code that can execute within an HTML page on the platform, including Force.com platform merge fields and expressions. ,[object Object],Visualforce conforms to the Model-View-Controller (MVC) development pattern by providing a clear division between the view of an application (the user interface, defined by Visualforce mark-up), and the controller that determines how the application works (the business logic, defined by a Visualforce controller written in Apex). With this architecture, designers and developers can easily split up the work that goes with building a new application—designers can focus on the look and feel of the user interface, while developers can work on the business logic that drives the app. ,[object Object],Visualforce pages can implement the same functionality as s-controls but with approximately 90% fewer lines of code. ,[object Object],Visualforce components are rendered intelligently by the platform. For example, rather than forcing page designers to use different component tags for different types of editable fields (such as email addresses or calendar dates), designers can simply use a generic <apex:inputField> tag for all fields. The Visualforce renderer displays the appropriate edit interface for each field. ,[object Object],Visualforce pages are compiled and rendered entirely by the Force.com platform. Because they are so tightly integrated, they display the same performance as standard Salesforce.com pages, regardless of the amount of data being displayed or edited. ,[object Object],Visualforce pages do not need to be rewritten when other parts of the Force.com platform are upgraded. Because the pages are stored as metadata, they are automatically upgraded with the rest of the system. When Should I Use Visualforce: The Salesforce.com prebuilt applications provide powerful CRM functionality. In addition, salesforce.com provides the ability to customize the prebuilt applications to fit your organization. However, your organization may have complex business processes that are unsupported by the existing functionality. When this is the case, the Force.com platform includes a number of ways for advanced administrators and developers to implement custom functionality. These include Visualforce, Apex, and the Force.com Web Services API. The Technologies behind a Force.com Platform App Now that we've talked about the kinds of apps the platform can build, let's review some of the technologies behind the platform itself. These technologies have a big impact on what the platform supports, and what it's like to develop on it. Table 1: Key Technologies behind the Platform TechnologyDescriptionMultitenantarchitectureAn application model in which all users and apps share a single, common infrastructure and code baseMetadata-drivendevelopment modelAn app development model that allows apps to be defined as declarative “blueprints,” with no code required. Data models, objects, forms, workflows, and more are defined by metadata.Force.com WebServices APIAn application programming interface that defines a Web service that provides direct access to all data stored in the Force.com platform from virtually any programming language and platformApexThe world’s first on-demand programming language, which runs in the cloud on the Force.com platform servers.VisualforceA framework for creating feature-rich user interfaces for apps in the cloudForce.com SitesPublic websites and applications that are directly integrated with your Salesforce.com organization—without requiring users to log in with a username and passwordAppExchangedirectoryA Web directory where hundreds of Force.com apps are available to Salesforce.com customers to review, demo, comment upon, and/or install.Developers can submit their apps for listing on the AppExchange directory if they want to share them with the community. A Multitenant Architecture The platform's multitenant architecture means that all users share the same physical instance and version of any application that runs on it. In contrast to their single-tenant counterparts, such as client-server enterprise applications or email servers, multitenant applications are designed so that any upgrades to the platform or the apps it supports happen automatically for all users at once Consequently, no one has to worry about buying and maintaining their own physical stack of hardware and software, or making sure that their applications always have the latest patch installed. Besides the Force.com platform, several popular, consumer-based applications also use a multitenant architecture, including eBay, My Yahoo!, and Google Mail. Multitenant architecture allows these applications to be low cost, quick to deploy, and open to rapid innovation—exactly the qualities for which salesforce.com have also become known. On-Demand, Multitenant Applications that Run in the Cloud The platform's multitenant architecture also impacts how developers use the platform to create new applications. Specifically, it defines a clear boundary between the platform and the applications that run on it. A boundary is important because it allows applications to define their own components without jeopardizing the functionality of the core platform or the data stored by other users. A Metadata-Driven Development Model The Force.com platform also uses a metadata-driven development model to help app developers become more productive in putting together apps. It means that the basic functionality of an app—that is, the tabs, forms, and links—is defined as metadata in a database rather than being hard-coded in a programming language. When a user accesses an app through the Force.com platform, it renders the app's metadata into the interface the user experiences. As a result of metadata-driven development, the Force.com platform app developers work at a much higher level of abstraction than if they developed applications using Java or C#, and are shielded from having to worry about low-level system details that the platform handles automatically. At the same time, Force.com platform developers can also leverage advanced features that the platform provides by default. Customizing your app's metadata might sound intimidating, but as you'll see in this book, the platform's user interface makes it easy. Anyone who is familiar with using a Web browser can quickly get up to speed, even if he or she doesn't know any programming languages. Developers who want to programmatically manage their app's setup can use the Force.com Platform Metadata Application Programming Interface (API). The Force.com Metadata API provides an alternative to the platform's user interface by allowing developers to directly modify the XML files that control their organization's metadata. Developers can also use the Metadata API to migrate configuration changes between organizations, and create their own tools for managing organization and application metadata. Although at first glance metadata-driven development may seem somewhat esoteric, it's exactly the same model for how Web browsers work. Instead of hard coding the definition of a Web page in a free-form programming language, a Web page author first defines the page as HTML, which is itself a kind of metadata. When a user requests a page, the Web browser renders the page using the metadata provided in the HTML tags. Even though the HTML/browser combination does not allow authors as much formatting power as they might get in a regular publishing tool, it simplifies the work of publishing content to a wide audience and increases the Web page author's overall productivity. Likewise, the Force.com platform vastly simplifies the work of building an app and increases a developer's overall productivity. And, like Web pages that use JavaScript or Flash to add functionality to HTML pages, the Force.com platform also provides ways for more advanced developers to add custom functionality to the apps you build. Visualforce Visualforce consists of a tag-based mark-up language that gives developers a more powerful way of building applications and customizing the Salesforce.com user interface. With Visualforce you can: • Build wizards and other multistep processes • Create your own custom flow control through an application • Define navigation patterns and data-specific rules for optimal, efficient application interaction. Apex Use Apex if you want to: • Create Web services • Create email services • Perform complex validation over multiple objects • Create complex business processes that are not supported by workflow • Create custom transactional logic (logic that occurs over the entire transaction, not just with a single record or object) • Attach custom logic to another operation, such as saving a record, so that it occurs whenever the operation is executed, regardless of whether it originates in the user interface, a Visualforce page, or from the Web Services API Force.com Web Services API Use standard Force.com Web Services API calls if you want to add functionality to a composite application that processes only one type of record at a time and does not require any transactional control (such as setting a Save point or rolling back changes). Common Issues Creating Visualforce Pages: The following are a list of things to watch out for when creating Visualforce pages: • Verify that your component tags start with apex:, that is, apex is followed by a colon. • Pay attention to warnings and errors, and make sure that your tags are well-formed, and that each opening tag has a closing tag. • Make sure that quotes and brackets match, that every quote and bracket has a match. • Verify that the controller or controller extension name are correct. CHAPTER 5 PROJECT DESCRIPTION Problem Definition: The Force.com platform is the world's first Platform as a Service (PaaS), enabling developers to create and deliver any kind of business application in the cloud, entirely on-demand and without software. It's a breakthrough new concept that is making companies radically more successful by letting them translate their ideas into deployed applications in record time. A building, sharing, and running business application has never been so easy. This is an application project for understanding and demonstrating cloud computing capabilities using Force.com. We use Sales Force features to achieve the goal. The scope of this project is limited based on the application developed in force.com. To develop an application for sales forecast details. Provide the Sales forecast details of a company product. Ease of access and use Secured analysis(confidentiality) ,[object Object],Overview of the project: This project deals with the concept of cloud computing. This cloud computing capabilities will be achieved by using the salesforce environment. The main theme of this project is to develop an application in sales force environment. The entire set up will be provided by the salesforce. The application will be developed in the languages called Visualforce and apex. The two languages will be particularly used in sales force to develop the web based applications. Initially the user has to register with the salesforce and have to get his ID. This user ID will be used to enter into the salesforce application development environment. The environment will be furtherly used to develop the applications. The pages setup inside this application will be used to customize the application. There are lots of tabs and links can be created here. The developer needs to register with the salesforce environment. The application needs to develop in this environment itself. The application will be completed and launched as a site. This site will work as an application. Platforms for Cloud Computing A new twist, the platform in the cloud, is making the delivery of application functionality even more interesting. Increasingly, applications that run in the cloud are starting to look less like websites and more like platforms, meaning they are starting to sprout Application Programming Interfaces (APIs), code libraries, and even programming models. Collectively, these new kinds of development technologies can be thought of as platforms to run apps in the cloud. Similar to traditional platforms, cloud computing platforms provide tools that allow developers to leverage existing functionality to create something new; however, because these platform tools are accessed freely over the Internet rather than through an operating system or package that was installed on a local machine, developers don't need to worry about the logistics of putting together an executable that will be installed on a user's machine. Anyone with a Web browser can access it! The possibilities presented by this new type of platform have emerged quickly, spurred on by the popularity of mash-ups—a website or application that combines tools from multiple cloud computing platforms to create new functionality. Some of the cloud computing platform tools used in today's mash-ups includes innovations like Google's search API, which allows developers to use the power of that search engine in their applications, eBay's APIs for auctions and listings, or Amazon.com's system for creating entirely new storefronts. For example, almost any real estate website or application these days uses Google or Yahoo! maps under the hood, illustrating how these new APIs are now commonly running alongside the more traditional database, app server, or operating system platforms. About Developer Force Developer Force is a community of developers who customize and build applications that run in the cloud and are built with the Force.com platform. Developer Force members have access to a full range of resources, including sample code, toolkits, an online developer community, and the test environments necessary for building apps. The Developer Force website includes an online version of this book and has information about the Dream force event that we hold every year for Force.com platform developers. If you need more info, have a question to ask, are seeking a toolkit or sample, or just want to dig a little deeper into Force.com platform development, Developer Force is where it all comes together. The Basics of an App: If you haven't used Salesforce.com before, you'll find it worthwhile to log in and spend a bit of time clicking around. Most Salesforce.com editions (including Developer Edition) have a basic Salesforce.com SFA app, so we'll start by looking at that. The interface for these tasks has a lot in common with the interface of whatever app you're planning to build. Tabs As you can see when you start clicking around, there are a few key elements that form the foundation of the Sales Automation app and of most applications created with the platform. First, across the top of the app is a set of tabs that segment the app into different parts. Each tab corresponds to a type of object, such as an account or contact, and within a tab you can perform actions on particular records of that tab's type. For example, when you click on the Accounts tab, you can create a new record for the “Acme” account. You can also edit existing accounts, or use a list view to filter lists of accounts by certain criteria. Most app development work revolves around creating tabs and defining the data and behaviours that support them. Forms A second key element is the form that is displayed as part of a tab. As in any business app, forms are the primary means of entering and viewing information in the system. Forms allow you to view and edit the data associated with a particular record on a tab, like the contact “Jerome Garcia” on the Contacts tab. When developing a new app you can define what information appears in each form, and how it is organized. For example, the form for a contact record includes fields such as Last Name, Home Phone, Mailing City, Title, Birth date, Reports To, and Account. In a Force.com platform app, the form used to enter information is referred to as an edit page and the read-only view of that information is referred to as a detail page. Links Finally, because Force.com platform apps are delivered via a Web browser, they use links to provide navigation to related data. For example, on an account detail page, there are links to related records, such as the contacts that belong to the account and the sales user who manages the account. Other links take you to recently visited records and to areas of the app where users can set personal preferences. These links provide navigation both within an app and out into the Web.
