Input-Output Strategies May 15, 2006
I came across an interesting and thought provoking post by Max Harris on his blog From Here to Modernity, where questions about I-O Strategies (when dealing with a critical table) evoked responses from more than 90 iSeries professionals.
Four options were presented as follows:
- Replacing F-specs in RPG program with SQL in all the programs or modules that use the table ( Embedded SQL ).
- Move I-O to a SRVPGM and have a procedure return the record format.
- Move I-O to a SRVPGM and have several procedures which return various data structures.
- Move I-O to a SRVPGM and have field getters and field setters (JAVA).
We all know that first option is not very efficient, but read the post and related comments and arrive at your own conclusion.
