Overview
The way decisions are made in organisations is changing. The biggest change is that they have to react faster. Studies are supporting this. For example, a study done in March 2011 showed that 43% of enterprises find that making timely decisions is becoming more difficult.  Managers increasingly find they have less time to make decisions after business events occur. The consequence is that it must be possible to change existing reports faster, and that reports must be developed more quickly. From this we can include that our BI systems have to be more flexible, more agile.

In addition, new forms of reporting and analytics are being requested by the user community, such as operational analytics, 360˚ reporting, exploratory analysis, deep and big data analytics, self-service BI, and semi-structured and unstructured data analytics.

All these new requirements demand that BI systems are developed in a more agile way. One of the technologies making this possible today is data virtualization. In a nutshell, data virtualization decouples data sources from the application and reports, and by doing that it can present a heterogeneous set of data stores as one logical database to all the reports. Compared to ETL, where data integration takes place in a scheduled manner, with data virtualization data is integrated on-demand.

The last few years, various data virtualization servers have become available to develop these systems, including those of Composite, Denodo, IBM, Informatica, Information Builders, Queplix and RedHat. In many projects they have already proven that data virtualization technology is mature, does simplify BI systems, and makes them more severely more agile.

This one day seminar focuses on data virtualization when deployed in business intelligence systems. The advantages of data virtualization are explained; products are compared, application areas are discussed; and the relationship with related topics, such as MDM, data governance, and SOA are also discussed.
