Re: Database I/O Modernization

Yuck...

There's no modernization here...

Better off just sticking to RPG RLA op-codes

The following link shows the RPG for a service program that encapsulates
database I/O.

It's essentially a template provided by Tembo Technologies as part of their
road-map and approach to application modernization. Tembo has promised an
open-source license.

https://rd.radile.com/rdweb/temp/cusmstio.txt

The interface is a single procedure call wherein the following parameters
may be passed:

Action code (e.g. I=Insert, U=Update, D=Delete, R=Read, etc.).
Buffer pointer (a reference to an externally defined data structure located
in the calling program).
Key Data Structure (contains the record key(s)).

Tembo's road-map calls for using this interface for RLA access for every
table and logical view in Db2 for i.

Questions:

Is this type of interface familiar to you?
What are the pros and cons of replacing existing I/O op codes with such
procedure calls?
Is this as an effective form of application modernization?
Would you recommend a different type of interface?

Thanks,

Nathan Andelin.
