A1AA WORKSHOP: Application Modernization Database

Sign up or log in to save this to your schedule and see who's attending!

Today, when we talk about application modernization, most think about having to reface their application and going mobile. New technologies will be used to change the layout and programs will be rewritten. … but what will a nice design be worth if the base, i.e. the underlying database is still in your grandfather’s style, grown over the years with lots of redundancies? In this workshop you will learn why to go from DDS to SQL, what are the benefits of SQL over DDS. Techniques for converting and redesigning your existing grown over the time database into a modern normalized database will be shown. In a modern environment database objects can and must be accessed from multiple interfaces and programming languages. For guaranteeing data integrity and security business logic and security rules should be moved into the database.

Learning Objectives:
Discover the advantages of SQL over DDS and the SQL enhancements within the last releases. Replace DDS described physical files with SQL Tables. Use SQL Indexes for native I/O instead of DDS described keyed logical files. Move business logic into database by using SQL views, materialized query tables and referential integrities. Add row and column access control (RCAC) for avoiding unauthorized data access. Start using instead of triggers to allow a further redesign of the existing data base. This session 170027.
