Best Practises for Extract, Transform, Load (ETL)

It is a common situation for the enterprise level software solutions to use many different software systems from different vendors in order to provide full coverage of the business functions. The integration between these systems often requires real time or off-line data migration as part of the operational communication between the systems or in order to populate analytical decision making systems on regular basis.
Another common scenario is the transition to a new software system which could be either a new version, but with different data structure or could be a different system from another vendor. The data migration has never been easy as it is usually performed using in-house built solutions with hard-coded algorithms for Extraction, Transformation and Load (ETL). This low level implementation makes the maintenance of such migration solutions a complicated job and can be a cause for hidden errors with the ETL processes on logical or technical level.
 
ETL process changes in a Validata environmemt. V-Conn can actually provide a data migration framework that is integrated with a set of components and covering an important number of data migration related functionalities and methodologies.
