Object Relational Mapping in Salesforce A Comprehensive Overview

1. ORM (Object-Relational
Mapping) in Salesforce:
A Comprehensive
Overview
Object-Relational Mapping (ORM) in Salesforce is a powerful technique
that allows developers to work with objects and databases seamlessly. By
mapping object-oriented models to relational databases, developers can
write efficient and maintainable code. This comprehensive overview will
explore the key concepts and best practices for implementing ORM in
Salesforce.

2. What is ORM?
Bridging the Gap Between Objects and Databases
Mapping Data Structures
ORM enables developers to work with
objects in code while mapping them
to relational database tables.
Seamless Integration
It facilitates seamless integration
between the object-oriented paradigm
and relational databases.
Elimination of Tedious Mapping
It eliminates the need for developers to manually map objects to database tables and
vice versa.

3. What is ORM?
Object-Relational Mapping (ORM) is a technique that allows developers
to work with objects in code while seamlessly mapping them to relational
database tables.
This process enables efficient data handling and manipulation, bridging
the gap between object-oriented programming and relational databases.

4. Benefits of ORM
• Simplified data access and manipulation: ORM simplifies the process of accessing and
manipulating data, allowing developers to work with high-level objects.
• Reduced complexity in database interactions: By abstracting the database interactions, ORM
reduces the complexity of working directly with relational databases.
• Increased productivity and code maintainability: ORM enhances productivity by streamlining
data operations and ensures code maintainability through a structured approach to database
interactions.

5. Traditional Database Interaction
Before the adoption of ORM, developers relied
on manual data mapping and executed direct
SQL queries to interact with databases.
This traditional approach often led to increased
complexity and time-consuming data
manipulation processes.

6. ORM in Salesforce
Object-Relational Mapping (ORM) capabilities within the Salesforce platform provide developers with a
seamless and efficient way to interact with databases. By leveraging Salesforce's native ORM,
developers can simplify complex database interactions, leading to more productive and maintainable
code.

7. Salesforce Objects and Records
Salesforce Objects (sObjects)
Objects in Salesforce represent database tables
where data is organized and stored.
They define the structure and behavior of the
data, including fields and relationships.
Records in Salesforce
Records are individual rows within objects and
contain specific data entries.
Each record corresponds to a unique instance of
an object, reflecting a specific set of field values.

8. Apex Data Manipulation
Object-Oriented
Apex is an object-oriented
programming language for
Salesforce.
Data Manipulation
Language
Developers use Apex to
perform database
operations in Salesforce.
Integrated with DML
Apex provides powerful
Data Manipulation
Language (DML) features.

9. ORM Frameworks in Salesforce
1 Salesforce Object Query Language (SOQL)
SOQL allows developers to query Salesforce's database for specific
information.
2 Salesforce Object Search Language (SOSL)
SOSL is used to perform text searches in records of Salesforce objects.
3 Apex Data Manipulation Language (DML)
DML enables developers to perform database operations in Salesforce's
Apex language.

10. SOQL (Salesforce Object Query
Language)
Detailed Syntax
Understand the intricacies of SOQL syntax to
write efficient queries.
Query Examples
