When talking about application modernization database most think about converting from DDS to DDL and redesigning the database … and yes, this might be the final goal. But there is much more … because we never can touch the database without respect to the application and vice versa. We have to move from an application-centric thinking to a data centric thinking. In short, instead of coding everything in whatever programming language, we should move as much business logic as possible into the database. It may even include foreign data that is provided and accessed by Web-Services.What does that mean?
