SQLite vs. libgda
A few things I have learned: DDL (Data Definition Language) varies significantly from one SQL implementation to another. It is much easier and faster to maintain an application for a single database backend rather than across many. libgda is great when you are designing an application specifically meant to manage arbitrary databases. libgda is overkill when all you need is to maintain a simple, local embedded database. SQLite is fast, lightweight, well-documented, and backed by an active IRC support community. Keep database-related code restricted to as few source files as possible. The SQLite source code is an excellent reference for understanding how to implement commands like .import. Using Git (or any modern version control system) saves an enormous amount of time.
