As developers of our own web software and contractors that currently support a large online reservations system (www.twibo.com), we’ve always had one major problem during the software deployment – synchronization of beta and live database structures.
There are usually some changes in the structure of the database tables between release X and release Y. It’s quite simple to add a few new tables to make the structure of the databases in sync, but it becomes a real pain when indices were updated in some tables, fields renamed or added or descriptions of the fields have changed.
Having searched for a web based solution for this problem and been unable to find one, I’ve decided to create my own. That’s how Stuffed SyncDB was born.

Shortcomings:
- Built with Perl — requires Perl with MySQL support to be available on the server where SyncDB is going to be installed.
- Can only synchronize MySQL databases structure (for now).
- Doesn’t take into account types of tables (was only tested with MyISAMI tables).
Features:
- Synchronizes two databases in 2 easy steps — select a source and target database from a list, click a button and you are set.
- Generates synchronization strategy (SQL statements that would make target database’s structure equal to the source database’s structure) that can be edited before it will be executed.
- Supports renaming of the fields — understands that if a field is missing in the target database it doesn’t necessary mean that it should be dropped.
- Allows to compare a database structure of a real database with a database structure dump.
- Allows to compare two database structure dumps with each other.
- Database structure dumps could be pasted in a textarea or uploaded as a file.
- You don’t need to have direct access to a remote database to synchronize it with your local one — just install Stuffed SyncDB on the same server with the target database and upload a dump of the source database structure.
Now the good news is this: Stuffed SyncDB will be free and would be released under a GPL license or similar. This would happen at the day of Stuffed Guys Relaunch*, when we will release Stuffed Tracker 2.0 and also show our freshly redesigned web site to the world.
* Hopefully this day would be 1st of September 2005.
I searched a long time tool like “MySQL structure synchronization”. When can I download it from Your webpage?
Peter,
The software is 99% ready, I just don’t have time to prepare it for the release right now. I think we should release it in January 2006, closer to the end.
Instead of a downloadable product we’ve launched a free service that does MySQL structure synchronization:
