I will design mysql postgresql database erd and sql queries

A well-designed database prevents duplicate data, broken relationships and slow queries as your application grows.

I will design a clean MySQL or PostgreSQL database for your website, SaaS product, CRM, inventory system or business application. I will translate your requirements into an organized schema with clear entities, primary keys, foreign keys and relationships.

Depending on your package, you can receive:

Entity relationship diagram

Normalized table structure

Primary and foreign key design

SQL database creation scripts

Useful select, insert, update and reporting queries

Index recommendations and query optimization

Clear schema documentation

I can design a new database or review an existing schema. Please contact me before ordering and share your features, data fields, user roles, reports and current technology stack. I will confirm the correct package and whether migration or optimization requires a custom offer.
