One key area of Oracle OpenWorld 2016 was data in various shapes. Big Data, streaming data and traditional transactional data. The power of SQL to access and unleash all data - even data in NoSQL databases. The advent of the citizen data scientist. Streaming data analysis in real time on vast and fast and vast data, data discovery. And the new Oracle Database 12cR2 release. Forms, APEX, SQL and PL/SQL.
Oracle OpenWorld 2016 Review - Focus on Data, BigData, Streaming Data, Machine Learning & Database Development

Oracle OpenWorld 2016 Review
Data - Database Development, BigData, BI
2. 2
Data
• ACID is expensive
• OLTP is a niche
• Moving data takes long – bring processing to data
• SQL is omnipresent – expose all data in an SQL friendly way
– Including NoSQL and data on Hadoop
• Data from the past should be able to help us predict the future
– Bring on machine learning (aka AI aka predictive analytics)
– Aided by the citizen data scientist in (Big) Data Discovery
• Fast Data (big data at high velocity) should be handled in real time
– Enter: Streaming Analytics & Apache Kafka
• Oh and ehm …. a next major release of Oracle Database is available
– 12cR2 – only on the cloud for now
– Highlights: Sharding, More PDB (“virtual database”),
Approximate Query Processing, Leverage In-Memory
even more, JSON document generation and faster
JSON processing, Analytic Views
3. 3
Learning
• How do we learn?
– Try something (else) => get feedback => learn
• Eventually:
– We get it (understanding) so we can predict the outcome
of a certain action in a new situation
– Or we have experienced enough situations to predict
the outcome in most situations with high confidence
• Through interpolation, extrapolation, etc.
– We remain clueless
4. 4
Machine Learning
• Analyze Historical Data (input and result – training set) to discover
Patterns & Models
• Iteratively apply Models to [additional] Input (test set) and compare model
outcome with known actual result to improve the model
• Use Model to predict outcome for entirely new data

Recent developments
• More compute capacity, smarter algorithms and better analytical tooling
– Evolving Machine Learning
– Smart text and speech analysis (NLP, ESA)
– Real time predictions become a reality
– Streaming (event) Analytics
– Visualization
– Citizen Data Scientist
– SQL against Big Data
• More data available & accessible
(IoT, Social, Media, IT operations,
business processes,…)
• Better/larger/cheaper/faster
data storage capabilities
22. 22
Traditional approach
• All enterprise data is in the Oracle [relational] Database
– Except very unstructured documents - and sometimes even those
24. 24
Variety in data – Data Tiering
• How long relevant (hot vs cold vs dead)?
• How fine grained and how accurate?
• What is it used for?
– By whom, where, in what way, using which tools
• What format is it in/should it be in?
• How to be processed?
• What confidentiality & integrity is required?
• How much of it?
25. 25
Trends around data storage
and data processing
• Take processing to data [to reduce data movement]
– Exadata SmartScan in Storage Cells (SQL & R processing)
– Hadoop MapReduce/Spark
– Coherence Processors
– Streaming Analytics
– Microservices, stand alone data domains
• Distributed data partitions – for scalability and parallelization [and fault
tolerance when also replicated]:
– Shards (Oracle Database 12cR2) and Partitioned External Tables
– TimesTen Velocity Scale – distributed In-Memory OLTP
– Hadoop HDFS, Apache Kafka
• New paradigms regarding transactional data
– CQRS (for example Oracle Database In Memory (read) / In Flash/On disk
(read/write), Write behind cache)
– Event Sourcing, Transaction Log
26. 26
Oracle Database
• How much of your data
– Arrives through (business) transactions that require true ACID?
– Is involved in current business operations?
– Will ever be updated [again]?
– Plays a direct role in integrity [of other records]?
– Is actively accessed [on a regular basis] ?
– Really has to be in the OLTP engine?
• How much of the data currently in your OLTP engine could be off-loaded
– If that data remains accessible through SQL (even from within the OLTP engine,
without altering existing queries) with reasonable response times
• What if such off-loading
– Improves performance of the OLTP engine for transactions
– Shortens batch jobs [by engaging distributed, scale out processing options]
– Opens up possibilities for advanced analytics
– Potentially lowers the cost [licenses & specialized hardware] for the OLTP engine
– Introduces some change and complexity
27. 27
Oracle Big Data SQL
• Big Data SQL: A ‘franchised query engine,’ enables scalable, integrated
access in situ to the entire Big Data Management System (BDMS)
– Meta data, Query execution, Workload Management, Data Optimization
– Primary role for Oracle Database – foundation for BDMS
See Statement of Direction: http://www.oracle.com/technetwork/database/bigdata-appliance/overview/sod-bdms-2015-04-final-2516729.pdf
29. 29
Oracle Forms
• Release 12.2.1.1 is available
– 12.2.2 (or 12.2.1.2) is planned for late 2016
– Support for Forms 12c: Premier Oct 2020, Extended 2023 – (and moving)
• Forms usually runs in browser – using the Java JRE plugin for Applets
– Modern browsers have stopped or will stop supporting the Java plugin
– Forms will either have to run on outdated browsers (IE, old versions of Firefox or
Chrome) or run outside the browser
– The main changes around Forms are around running Forms outside the browser –
as standalone Java Web Start (jnlp) application
– Also: Forms Helper – script for customizing post-install environment (simplified
WLST)
• On Reports:
– Reports 12c exists – it is the terminal release
– From now on, reporting should be done using BI Publisher
– BI Publisher has become part of the Developer Suite and will be included in the
WebLogic Suite
31. 31
APEX – 5.1
• Interactive Grid – A new rich, client-side region type that allows editing multiple rows of
data in a dynamic, JSON-enabled grid, and supports multiple grids on a single page.
• Master / Detail / Detail – Provide a wizard interface to define declarative
master/detail/detail regions.
• New Charting Engine – Include a new JavaScript (Oracle JET) based charting engine
developed by Oracle which produces responsive and accessible HTML5 charts.
– AnyChart is on the way out
• Ability to have multiple tabs open to the same APEX application and isolate session
state
• Improved Wizards - fewer steps and more attributes set by default.
• Declarative RTL Support –declarative methods to control user interface direction-
support for both Left-to-Right and Right-To-Left languages.

Oracle Application Express 5.1 introduces a new component, the interactive grid, that combines the best of both interactive reports and tabular forms while lifting restrictions such as allowing for only a single tabular form region on a page. The interactive grid is a rich, client-side region type that allows editing multiple rows of data in a dynamic, JavaScript Object Notation-enabled grid that supports multiple grids on a single page. I
build highly interactive master detail pages so loved by Oracle Forms developers.
Oracle Application Express 5.1 is a huge leap forward in end user productivity. In this session see how the interactive grid brings dynamic, rich-client reporting and multirow editing capabilities to your Oracle Application Express applications and how the new, powerful charting engine (based on Oracle JavaScript Extension Toolkit ) enables users to visualize and interact with their data like never before. The session also takes an in-depth look at numerous other enhancements, such as the new live template options, support for right-to-left languages, and the future of the page designer with the integrated component view.
the new data visualization capabilities available with Oracle Application Express 5.1, based on the Oracle JavaScript Extension Toolkit and other components. Oracle JavaScript Extension Toolkit is a JavaScript charting solution that is highly customizable, accessible, interactive, and incorporates automatic responsive design support. See how easily you can integrate these great looking visualizations to tell a story in your application.
