Time to start discussing the second big step in our database modernization methodology: moving business rules to the database. It’s going to be an interesting trek, and I hope you join me in it!
By Rafael Victória-Pereira
The previous four TechTips (you might want to re-read those articles, starting here) covered the conversion of DDS files to DDL objects, which is the first of three database modernization steps (convert the DDS files to DDL objects, move business rules to the database, and take advantage of DB2’s advanced functionalities). The general idea is that you’ll gain a lot with these steps, in terms of performance, database user-friendliness, and flexibility. It’s not an easy path, and some steps may sound a bit weird (yes, I can imagine what you’re thinking about step two, which I’ll start explaining in this TechTip), but it’ll make sense in a while.
