@Joni: one point of criticism: one SRVPGM per view, not per file!!! Never use a file (table) in any SQL statement.
The most important topic is: decoupling database access from database design and implementation. Using SQL based DAOs for all access to the database opens up the possibility to rearrange data, as long as you could provide views with the same capabilities. (here you could win back performance, you've lost by replacing native I/O with SQL).
@Dave: +1
- with one question: who is responsible for the state of the process?
