Business Intelligence Forum 2010

Average: 3 (1 vote)

On Wednesday May 12 celebrated the 10th Forum of Business Intelligence, which has been Dataprix Media Partner and I had the opportunity to attend.

The event was quite interesting, and it was a good opportunity to learn first-hand opinions and impressions of deployments responsible for business intelligence projects.

I find it very appropriate that most of the interventions were responsible for the area of IT or business data warehouse, as the vision and how to communicate to the person who runs a project internally is often the most realistic and that can best explain the needs, problems and what actually can be considered at the level of business success or failure of a technology project.

Average: 3 (3 votes)

In the market for a Data Integration is a leading manufacturer Informatica. This company is the first independent provider of data integration software. His best-known tool and the heart of his platform is Informatica PowerCenter, which has gone through many versions, and is a reference in the world of integration.

But apart from PowerCenter, Informatica also has other tools that focus on more specific purposes, while that are integrated into the platform, and always in the context of Data Integration.

Data Warehouse Architecture: data areas of our Corporate Data Warehouse

Average: 2.9 (4 votes)

Areas de datos para la carga de un Data WarehouseWhen designing the architecture of a data warehouse system we have to raise different environments for which data must pass en route to its Data mart or target cube. Given the amount of changes that have to do, and normally the DWH, besides fulfilling its function of support analytical
requirements, performs a data integration function that will form the Corporate store and they will have to be also consulted the traditional way by the operational systems, it is recommended to create different data areas in the path between source systems and OLAP tools.

Each of these areas as characterized by the functions performed, how data is organized in the same, and what type of need can service. The area that is 'at the end of the road' is important, but it will not be the only store data that will exploit the reporting tools...

The suites of Oracle Business Intelligence

Cuadros de mando de Oracle AnswersOracle, in addition to their famous manager database has a large catalog of software products, many developed internally and acquired through the purchase of other companies.  Within the environment of business intelligence that fact is even more remarkable as just more of Oracle's recent acquisitions were purchases of BI software vendors.
 
The result is that although each tool has some features and a more appropriate market, there are many overlaps, and costs a little lie when choosing what software or set of tools we could use for our business intelligence project...

The error ORA-30926 as a result of a Merge

Average: 3.3 (4 votes)

ORA-30926 error usually occurs when performing merge operations, and typically we leave something descolocados as the description of it does not give too much information about what is happening: 
ORA-30926: unable to get a stable set of rows in the source tables.

Normally this error occurs when the merge operation to target a row to be updated on it more than one row in the table source. As the engine does not know what to choose register returns an error. It is a problem of duplication in the origin table.

Example:

  • We have: 
    TABLA_ORIGEN with the values 
    ID Description 
    1 'The first value' 
    1 'The value with duplicate id' 
    2 'Another value'

Informatica World 2008 in Las Vegas

Average: 3 (1 vote)

Finally I could attend the Informatica World 2008, now I'll try to explain what I found there. The conference was held under the slogan 'Gain the Edge'  from june 3 to 5.

First day began (after breakfast) with a general session entitled Vision. Strategy. Technology Announcements. Industry leadership. At the session both Sohaib Abbasi, President and CEO of Informática, as Chris Boorman, Ivan Chon and Girish Pancha, Vice-presidents in the Marketing, Data quality and Data integration areas respectively, showed their vision of current market, how technology and business are evolving and what role play in this context data and data-related aplicacions.

Much of what was familiar to me, because I had seen before at the Powerday 2008 Barcelona. This is an indicator that the company maintains a well-defined strategy, and shares with its partners.

Each speaker under the perspective of his area made particular emphasis on data value and the importance for each organization of the ability to maintain consistency and quality, ensure on time data availability, protection, sinchronization, and eficient data management and exchange with other organizations.

We noted that now having a Data Warehouse System that delivers new information every certain hour interval is insuficient. Internet and technological development, the globalization and our competitors are the reason. We heard repeatedly terms like SaaS, Real Time and Data Quality, clues about the new features of Powercenter and other tools of the company.

They also made an interesting demo about how an application like Salesforce.com can be synchronized in real time through the internet with a Google Docs spreadsheet. This cloud to to cloud computing example was made showing Salesforce.com on left screen and Google spreadsheet on right screen, each controlled by a laptop. The made a change in Salesforce.com data, and we saw how Google spreadsheet was automatically updated. Then they made a change in the spreadsheet and we saw how Salesforce.com data was also updated. Finally, they repeat the last part, but using an iPod Touch instead of the laptop. We must consider the opportunities that new mobile devices bring when we connect it to Internet.

Datacleansing with Oracle Warehouse Builder

In the link Managing Dates Quality can be agreed to an article of Ron Hardman on how carry out data cleaning processes with Oracle Warehouse Builder.

The article begins with an introduction to the quality of the data and ways to negotiate it, being one of them the utilization of the data cleaning options of Oracle Warehouse Builder.

The interesting thing is that is shown how to discharge a script with data of test, and how to configure the tool to test the utilities of Profiling, definition of Rules (Dates Rules), and correction or cleaning of the data. In this manner can be seen and to test in a simple way how to implement a basic process of Dates Cleansing with this tool.

The original article is in English but seeking in the web of Oracle I have found the 3 documents that enclosed, translated the Spaniard, and related to OWB and the cleaning of data:

  • Executive report - Oracle Warehouse Builder 11g Version 1 General Information
  • Oracle Warehouse Builder Dates Quality Option
