FAQ
Do you need access to my live database server?
No. To protect your security and keep the workflow efficient, I do not need remote access to your server. I only need your database schema (table structures, data types) or an ER diagram. I will deliver the solution as a clean .sql script file that you can execute safely on your end.
Which database management systemsdo you support?
I specialize in relational databases, specifically MySQL, PostgreSQL, Oracle SQL, and PL/SQL.
What do I need to provide to start the order?
You must provide a clear description of the logic or data you want to retrieve/manipulate, along with your database schema (DDL export, table creation script, or clear screenshots of your table structures and relationships).
