FAQ
Do I need to provide anything before placing an order?
Yes, please message me before ordering. To create the perfect schema, i need a brief description of your project, a list of the main features you want to track(e.g., users, products, orders), and your preferred database system (like MySQL or PostgreSQL).
What tools do use to create the ER diagrams?
I use professional visual modeling tools like dbdiagram.io and Lucidchart. I will deliver the final Entity-Relationship Diagram (ERD) as a high-resolution PNG/JPEG image, along with the source file so you can easily edit it in the future.
Will the SQL scripts work directly on my database server?
Absolutely. I write clean, structured-compliant SQL code tailored specifically to your chosen database engine (MySQL, PostgreSQL, etc.). All script files will include clear comments explaining how to run them and what each section does.
