Chapter 8. Externalizing data access
In our journey of database modernization we have:
Reversed engineered the database definition and now the database has been defined by
SQL
Created I/O modules to access DB2 data
Normalized and moved the business rules to the database
In the final stage of the proposed methodology we are proposing the use of stored
procedures, triggers, and user defined functions to complement and enhance the database
access.
In this chapter we discuss how triggers, stored procedures, and user defined functions can
assist you in moving more of the business logic into the database.
