FAQ
What do I need to provide to get started?
A brief description of your project requirements, any existing schemas/spreadsheets (.csv, .xlsx), or a rough outline of the data entities and relationships you want to build.
What database platforms do you support?
I work extensively across MySQL, PostgreSQL, SQLite, Oracle SQL, and Microsoft SQL Server. Scripts are formatted specifically for your target platform.
What file formats will I receive in the delivery package?
You will receive a .sql script containing full DDL/DML setup, a compiled .db SQLite file for immediate local use/testing, .csv data exports, and a simple README.txt guide.
Can you help normalize my unorganized spreadsheet into a SQL database?
Yes! I can analyze your flat Excel or CSV data, break it down into clean relational tables (up to 3NF), and generate the migration scripts to load it cleanly.
