About this Gig
I will diagnose and improve MySQL or SQLite databases used by websites and web applications.
I can help with incorrect SQL queries, inefficient queries, database structure, relationships, data consistency, schema changes and application/database integration problems.
I work from the actual database structure and application requirements rather than applying generic SQL recipes.
If your database contains production data, I will favor safe and reversible changes whenever possible.
For migrations or large databases, please contact me first so the scope and backup requirements can be evaluated.

FAQ
What database problems can you help with?
I can work on SQL errors, incorrect queries, slow queries, database structure, relationships, schema changes, data consistency issues and PHP integration with MySQL or SQLite.
Will you modify my production database directly?
Only when appropriate and with your agreement. For sensitive databases, I strongly prefer working from a backup or test copy first and using changes that can be reviewed or reversed.
Do I need to provide a database backup?
For structural changes, migrations or any work involving important production data, a recent backup is strongly recommended. I can tell you what type of export is needed before we start.
Can you recover deleted or corrupted data?
This Gig is primarily for database development, troubleshooting and optimization. Data recovery depends heavily on the available backups, database files and type of corruption, so please contact me before ordering for recovery work.
Can you optimize a slow database?
Yes, when the slowdown is related to SQL queries, indexes, schema design or application/database interaction. I will first identify the likely bottleneck rather than applying generic optimizations blindly.
