The latest addition to Mertech's BTR2SQL product line, the MySQL driver is designed to run applications developed for Btrieve and Pervasive transactional engines to work with MySQL without incurring expensive re-engineering costs. Mertech's plug-in architecture enables companies to support multiple databases with the same source base, including Pervasive.

MySQL has been the most popular open source database in the market for a some time now. It is also gaining increasing momentum as an embedded Database for applications requiring less maintenance, small memory footprint and at a lower cost of ownership. For Btrieve users, MySQL is a logical choice and the BTR2SQL for MySQL product aims to simplify the migration to MySQL for customers looking to either switch from Btrieve/Pervasive or offer MySQL in addition to their Pervasive based solutions.

Mertech's ISDBC driver uses the native C API of MySQL for communicating and accessing the MySQL database. This provides the fastest access to MySQL without being dependent on installing and configuring an ODBC driver.

Requirements

BTR2SQL requires accurate DDF for migrating existing database to the target back end. The BTR2SQL product bundle includes a database driver DLL and a GUI migration tool that takes existing Btrieve/Pervasive table structures and migrates them to the new database server. However, for your application to work accurately with the new database, it is important that the tables and indexes are created accurately on the target back end. The Mertech migration tool relies on the DDFs to get the database structure information; inaccurate DDFs will create inaccurate table structures.

To ensure the integrity of the DDF, Mertech provides a DDF Validation tool that checks for common issues in DDFs, such as the total length of fields not matching the Btrieve record size for the file, and generates a detailed report. However, if you might have valid but inaccurate information in the DDF, for example field length or field type or index definitions may not match what the program is expecting, then such inaccuracies will have to be corrected before migration.
