New features for Developers in Oracle 12c & Tools

Posted on

Continuing on from my previous posts on new features in the Advanced Analytics Option and the 12c Databases, this post will focus on the proposed new features for Developers in 12c and in the new releases of the development tools.

Health Warning: As with all the presentations at OOW that talked about what may be in or may be in the next release, there is no guarantee that these features will actually be in the released version of the database. Here is the slide that gives the Safe Harbor statement.

  • APEX 4.2 is out now and has lots of new features in particular features for creating mobile applications including transitions, gestures, changes in orientation and HTML 5 support. Coming in 12c APEX will be able to support the pluggable database environment. You will have the option to install APEX in the Contain database or in the pluggable databases. It will also support the extended VARCHAR2 size
  • SQL Developer will have Data Pump to allow for fast movement of data and for scheduling of the movements. The Database Difference tool has been redesigned to give more options and gives a more reliable comparison. A redesigned Database Copy (more options), improved Migrations and PDF report generation. SQL Developer is not the admin tool to manage the APEX Listener. UI improvements include more/better drag and drop, GRANT statement support in SQL editor and database Doc reporting. A new release of SQL Developer will be made available with the release of 12c that includes all the 12c new features
  • Better Data Compression of data being sent to/from the client/server. So how you use the ORDER BY clause will become more important
  • We will now have BOOLEAN in 12c but only in PL/SQL Sad smile
  • 12c will allow you to grant ROLES to PL/SQL program units. Or we could specify a White List that lists what other code units can call your code. This is a great security enhancement, although it involves more admin work, but it is worth it.
  • 12c will allow you to include PL/SQL in WITH
  • 12c will allow you to create duplicate indexes on the same set of columns. Sometimes you might want two different types of index on the same data, for example a bit map index and a b-tree index.
  • Cursor results sets can now be returned implicitly instead of the existing explicit method
  • The Warning messages when compiling our PL/SQL code can be filtered based on if they are Severe, Performance related or just Informational. This can be set at a System or Session level.

alter session set plsql_warnings=’enable:severe’;

alter session set plsql_warnings=’enable:performance’;

alter session set plsql_warnings=’enable:informational’;

There was a large number of exhibits at OOW. All of them were giving things away. For some of these you had to endure a sales pitch. One of the popular type of give away was a t-shirt. If you really wanted to, you could get enough t-shirts to keep you going for a few years. I popped into the exhibits for JavaOne and the pictures below is my faviourate t-shirt from OOW, by CloudBees.

Some of the exhibits were also giving away money. If you would sit through a 10 minute presentation you were given a ticket and if your number was picked your would could win anything from $20 up to $100. Many thanks to Intel Smile

Oracle Advanced Analytics Option in Oracle 12c

Posted on

At Oracle Open World a few weeks ago there was a large number of presentations on Big Data and Analytics.  Most of these were marketing type presentations, with a couple of presentations on using R and how it can not be integrated into the Oracle Database 11.2.

In addition this these there was one presentation that focused on the Oracle Advanced Analytics (OAA) Option.

The Oracle Advanced Analytics Option covers the Oracle Data Mining features and the Oracle R Enterprise features in the Database.

The purpose of this blog post is to outline and summarise what was mentioned at these presentations, and will include what changes are/may be coming in the “Next Release” of the database i.e. Oracle 12c.

Health Warning: As with all the presentations at OOW that talked about what may be in or may be in the next release, there is not guarantee that the features will actually be in the release version of the database. Here is the slide that gives the Safe Harbor statement.

  • 12c will come with R embedded into it. So there will be no need for any configurations.
  • Oracle R client will come as part of the server install.
  • Oracle R client will be able to use the Analytics functions that exist in the database.
  • Will be able to run R code in the database.
  • The database (12c) will be able to spawn multiple R engines.
  • Will be able to emulate map-reduce style algorithms.
  • There will be new PREDICTION function, replacing the existing (11g) functionality. This will combine a number of steps of building a model and applying it to the data to be scored into one function.  But we will still need the functionality of the existing PREDICTION function that is in 11g. So it will be interesting to see how this functionality will be kept in addition to the new functionality being proposed in 12c.
  • Although the Oracle Data Miner tool will still exits and will have many new features. It was also referred to as the ‘OAA Workflow’.  So those this indicate a potential name change?  We will have to wait and see.
  • Oracle Data Miner will come with a new additional graphing feature. This will be in addition to the Explore Node and will allow us to produce more typical attribute related graphs. From what I could see these would be similar to the type of box plot, scatter, bar chart, etc. graphs that you can get from R.
  • There will be a number of new algorithms too, including a useful One Class Support Vector Machine. This can be used when we have a data set with just one class value. This algorithm will work out what records/cases are more important and others.
  • There will be a new SQL node. This will allow us to write our own data transformation code.
  • There will be a new node to allow the calling of R code.
  • The tool also comes with a slightly modified layout and colour scheme.

Again, the points that I have given above are just my observations. They may or may not appear in 12c, or maybe I misunderstood what was being said.

It certainly looks like we will have a integrate analytics environment in 12c with full integration of R and the ODM in-database features.

Here are the abstracts from the two main Oracle Advanced Analytics presentations by Charlie Berger and Mark Hornick

Oracle Data Mining – A Component of the Oracle Advanced Analytics Option

This Hands-on Lab provides an introduction to Oracle Data Mining and the Oracle Data Miner GUI.

Oracle Data Mining (ODM), now part of Oracle Advanced Analytics, provides an extensive set of in-database data mining algorithms that solve a wide range of business problems. It can predict customer behavior, detect fraud, analyze market baskets, segment customers, and mine text to extract sentiments. ODM provides powerful data mining algorithms that run as native SQL functions for in-database model building and model deployment. There is no need for the time delays and security risks of data movement.

The free Oracle Data Miner GUI is an extension to Oracle SQL Developer 3.1 that enables data analysts to work directly with data inside the database, explore the data graphically, build and evaluate multiple data mining models, apply ODM models to new data, and deploy ODM’s predictions and insights throughout the enterprise. Oracle Data Miner work flows capture and document the user’s analytical methodology and can be saved and shared with others to automate advanced analytical methodologies.

Oracle R – A component of the Oracle Advanced Analytics Option

This Hands-on Lab provides an introduction to Oracle R Enterprise.

Oracle R Enterprise, a part of the Oracle Advanced Analytics Option, makes the open source R statistical programming language and environment ready for the enterprise by integrating R with Oracle Database. R users can interactively and transparently execute R scripts for statistical and graphical analyses on data stored in Oracle Database. R scripts can be executed in Oracle Database using potentially multiple database-managed R engines – resulting in data parallel execution. ORE also provides a rich set of statistical functions and advanced analytics techniques.

In this lab, attendees will be introduced to Oracle’s strategy for R, including the Oracle R Distribution, Oracle R Enterprise (ORE), and Oracle R Connector for Hadoop (ORCH). We will focus on Oracle R Enterprise with hands-on exercises exploring the transparency layer, embedded R execution, and statistics engine.

What has Oracle done to R to give us ORE

Posted on

Oracle R Enterprise (ORE) was officially launched over the past couple of days and it has been receiving a lot of interest in the press.

We now have the Oracle Advanced Analytics (OAA) option which comprises, the already existing, Oracle Data Mining and now Oracle R Enterprise. In addition to the Oracle Advanced Analytics option we also 2 free set of tools available to use to use. The first of these free tools are the statistical functions which are available in all versions of the Oracle Database and the second free tool is the Oracle Data Miner tool that is part of the newly released SQL Developer 3.1 (7th Feb).

What has Oracle done to Oracle to make Oracle R Enterprise ?

The one of the main challenges with using R is that it is memory constrained, resulting in the amount of data that it can process. So the ORE development team have worked ensuring R can work transparently with data within the database. This removes the need extract the data from the database before it can be used by R. We still get all the advanced on in-Database Data Mining.

They have also embedded R functions within the database, so we an run R code on data within the database. By having these functions with the database, this allows R to use the database parallelism and so we get quicker execution of our code. Most R implementation are constrained to being able to process dataset containing 100Ks of records. With ORE we can now process 10M+ records

In addition to the ORE functions and algorithms that are embedded in the database we can also use the R code to call the suite of data mining algorithms that already exist as part of Oracle Data Miner.
