Have you picked up the TI sheets from www.ibobjects.com/TechInfo.html ?The
ones on Client/Server programming and Datasets would be a good place to start.

"Think thin", especially for non-interactive utilities.
Don't assign SQL in loops. Seriously exploit the WHERE clause and
replaceable parameters - prepare once, run often.
Don't destroy and recreate objects that you will use repeatedly.

Use tib_dsql for straight DML. Use ib_cursor for sets you have to walk
through.
Don't request multi-row sets if you can get the same data from a singleton
- don't forget about GROUP BY for getting totals.
