In this video we take a look at techniques for migrating applications from the BDE to the DB-Express 4 Framework (DBX4), in particular BlackFishSQL (now obsolete). This video is a bit under 45 minutes long and you can watch it here.  This video is a replay of my presentation at CodeRage III on December 2, 2008.  The current recommendation is to use FireDAC as the database engine of choice for BDE migrations.
