Veelgestelde vragen
What do I get in each package?
ERD for up to 5 tables. Standard: normalized schema, ERD, SQL script and data dictionary for up to 12 tables. Premium: up to 25 tables plus indexing tips, sample data and full documentation.
Which databases do you design for?
MySQL, PostgreSQL, SQLite and SQL Server. Each order covers one database engine. Not sure which one fits your project? Message me and I’ll recommend the best option.
Can you fix or redesign my existing database?
Yes. Send me your current structure (SQL dump or screenshots) and I’ll redesign it. Pricing is based on table count, so pick the matching package or message me for a custom offer.
Do you also build the app or backend?
This gig covers database design only: ERD, schema and SQL script. Your developer can use my files directly. For app or backend development, message me and we can discuss a separate order.
I’m not technical. Can I still order?
Absolutely. Just describe your project in plain English: what you want to store and how it works. I handle the technical side and explain everything simply
What files will I receive?
ERD as PNG and PDF, SQL script as a .sql file, and the data dictionary as PDF or Excel. Standard and Premium also include the editable source file of your diagram.
What if I need more tables than my package includes?
Add the 5 extra tables option to your order or choose the next package. Not sure how many you need? Message me your idea first and I’ll estimate it.
How many revisions do I get?
Basic includes 1, Standard 2 and Premium 3. Revisions cover changes within the agreed project. A major change of direction after delivery is treated as a new order.
