The role of a system for the control of the data bases and the facilities offered by it is highly important in the success and performance of an executive informatics system. From this point of view, the analyze will take into account the facilities of working with evolved data bases and storages of data, the implementation of some OLAP functionalities an data mining but also the integration of data and applications coming from different sources, the way in which the process of extraction, transformation and loading of this data in the final storages takes place, the easiness in administration and the instruments offered for the developing of interfaces.

One important point of this analyze refers to the performance in interrogation, both on operational data bases and the extraction of data from data storages.
