FAQ
Which database systems do you support?
I primarily work with MySQL, MariaDB, Microsoft SQL Server, SQLite, and MongoDB. Please contact me before ordering if your project uses a different database platform.
Will you create an ERD?
Yes. ERD and schema diagrams are included in the Standard and Premium packages. A basic ERD can be added to a custom Basic order if required.
Can you improve an existing database?
Yes. I can review an existing database, correct table relationships, improve normalization, add indexes, fix SQL queries, and recommend structural improvements.
Can you write complex SQL queries?
Yes. I can write joins, subqueries, aggregate queries, views, functions, stored procedures, triggers, and CRUD queries based on your requirements.
Is a web admin panel included?
No. This gig covers database design and SQL development. A PHP web interface or admin panel requires a separate custom offer after reviewing the required pages and functionality.
Will you provide the SQL source file?
Yes. You will receive the SQL database script and the other files included in your selected package, such as the ERD, documentation, or sample data.
