Oracle Data Visualization Desktop (DVD)


Oracle Data Visualization Desktop (DVD) has been released and now all the BI Bloggers including myself who did not get a beta copy are scrambling to review and post their thoughts.
The functionality of Data Visualization is not new the Business Analytic tools offered by Oracle.  OBIEE 12c and BI Cloud Services (BICS) have Visual Analyzer Projects and then there is Data Visualization Cloud Service (DVCS).  But Data Visualization Desktop (DVD) is Oracle's truly first direct to any data source desktop tool since the days of Interactive Reporting.
Now full disclosure, I am a true fan of Interactive Reporting.  I cut my business intelligence teeth on Brio 6.0 back almost 18 years ago.  I really like Interactive Reporting.  It provided direct access to almost any database via ODBC and could import local data files.  You had graphical data modeling, query and analysis and dashboards along with paginated reporting. All in All it was and I argue still is a great tool.  

But in the age of acquisitions Oracle made a decision to take its acquisition of Siebel Analytics and make it the new face of Oracle Business Intelligence Enterprise Edition. Unfortunately, Interactive Reporting which came along a few months later with the acquisition of Hyperion became the "Redheaded Stepchild" and was relegated to "Not a Strategic Product" along with SQR and Web Analysis.
Alright…enough of nostalgia lane!

The Desktop install comes with two sample datasets and sample Visual Analyzer Project to showcase some of the features and capabilities.

The part the interested me the most was direct to data access.

The Data Sources panel provides access to existing Data Sources, capabilities to create new data sources and manage connections.

Clicking Create New Data Source brings up the following dialog.

From a File is self explanatory and nice way to include non-curated data in an analysis.  

From Oracle Applications is interesting, if you read the print below the option you see 

 "Select an Analysis containing the data you want to visualize."
 
 Looking at this Option I see that I can connect to an existing OBIEE instance.
 
After setting connection information and Signing in I see the OBIEE catalog I have access to
 
 
Navigating to an analysis
 
Reviewing and retrieving the data from the analysis
 
 My analysis is now a data source that can be used
 
My Data Source in a Visual Analyzer Project
 
The option to create data source from Database provides access to a large number of databases
 
Connecting to the database I can see the tables
 

Selected table is displayed and the columns can be inspected.
 
The data source is imported into DVD and is available for building a VA Project.
 
To add more data sources you can add in the Data Sources interface or you can add within the Visual Analyzer Project.
 

Adding requires you to go through the steps of creating a data source, picking a data source type and if the database already has connection then selecting the table. 
 
When the data source is added from within VA Project a wizard drives how that table will be used - Extend a Fact or Extend a Dimension.  If Extend a Dimension then the matching column is established.

 
Looking at the Source Diagram the relationship link is displayed.
 
 
Dimensions can be extended as well.
 
And when additional supporting dimensions are added and a complete model is built for the project the relationships of the data sources is more evident.
 
Now the diagram may be a bit confusing with some thinking that there are joins between all the tables but if you look closely you see the darker lines with numeric value showing actual joins.
 
 
So, my first impressions are that it is an easy tool to navigate and get into data analysis rather quickly.  I like that I can create multiple data sources from many different sources and add them into a VA Project.
 
I would like to see the ability to add more than one data source at a time. 
 
There will be many more blog posts by others in the weeks to follow and I look forward to their impressions.

Public API’s for FA Transactions

Public API’s for FA Transactions So far Oracle FA is have all the good things except the lack on reporting.Oracle FA is now offer lot of public API's that can be used to interfacing with third party or Oracle application other modules. Here are some of transaction's API's:   Additions API if you have requirement to add assets directly via PL/SQL then use  FA_ADDITION_PUB.DO_ADDITION. If you have selected the Allow CIP Assets check box on the Book Controls window of a tax book when adding CIP assets using the Additions API, the this API automatically adds those CIP assets to that tax book at the same time that they are added to the corporate book. Adjustments API you can make cost adjustments to your assetsdirectly via PL/SQL using  FA_ADJUSTMENT_PUB.DO_ADJUSTMENT  for any  process adjustment. Detail can be found in appendix H) You can use this API if you have a custom interface that makes it difficult to use with the existing Oracle Assets interfaces for adjusti...

Unbilled Receivables and Unearned Revenue Accounting in Oracle Projects

Unbilled Receivables and Unearned Revenue Accounting in Oracle Projects Introduction When it comes to contractual billing, invoice and revenue generation are two separate processes, which during the lifespan of a project may or may not always coincide with each other and so do the balances in revenue and receivables accounts.  This interim difference between revenue and invoice account balances is bridged using Unbilled Receivables (UBR) and Unearned Revenue (UER) Accounts. Unearned Revenue (UER) Unearned Revenue (also termed as deferred revenue or UER) signifies money received for the goods or services, which are yet to be delivered.  As per the principles of Revenue Recognition, UER is recorded as on the balance sheet unless it is converted to Revenue upon delivery of goods or services For Example XYZ Consulting Ltd. receives an annual maintenance contract of $ 12,000 on Dec 31, 2014 for the period of Jan 01, 2015 to Dec 31, 2015. At the start of the contract as of Dec 31, 2...
