FAQ
Which database platforms do you support?
I work with all major relational databases, including SQL Server, MySQL, PostgreSQL, Oracle, MariaDB, and SQLite. If you use a different platform, please message me before ordering to confirm compatibility.
Can you design a database from my case study or business requirements?
Yes! I can analyze your business rules or case study, identify entities and relationships, create ERD diagrams, and deliver a normalized relational schema that’s ready to implement.
Do you provide the actual database files or just the diagrams?
All packages include SQL scripts for table creation. Standard and Premium packages also include a fully implemented database that you can import directly into your chosen platform.
What if I already have a database but it’s slow or poorly structured?
can review, troubleshoot, and optimize your existing database by fixing design issues, improving queries, adding indexes, and enhancing performance — included in the Premium package or as a custom offer.
Do you offer revisions or post-delivery support?
Yes, I include revisions within the gig scope until the agreed requirements are met. Premium orders also come with 7-day post-delivery support for any minor fixes or clarifications.
