Are you searching for replacement of the BDE in Delphi or in C++Builder? One of the option is the widely used and deployed DBISAM. It is licensed per-developer, and includes royalty-free distribution. License management isn’t required at all, and the money that you used to pay to the database engine vendor is now your profit to keep.
With Elevate Software, you are backed by a company that has over a decade of experience in highly-distributed and pre-packaged database application software. You don’t need to use a feature-crippled « free » product in order to avoid licensing fees anymore. This version comes with source code.
