Database Schema & ORM
Design an efficient database schema for core SaaS entities and integrate an Object-Relational Mapper (ORM) for data interaction.
Database Schema: The Blueprint
Imagine building a house. You wouldn't just start laying bricks, right? You'd need a blueprint!
A database schema is exactly that: a blueprint for your database. It defines the structure of your data, including the tables, columns, data types, and relationships between them.
For a SaaS application, a well-designed schema ensures your data is consistent, easy to manage, and performs efficiently as your user base grows.
Core SaaS Entities
Every SaaS application deals with certain fundamental pieces of information. These are often called entities.
Common entities you'll find in most SaaS apps include:
- Users: Who uses your service?
- Products/Plans: What do you offer?
- Subscriptions: How do users pay for your service?
- Payments: Records of transactions.
Each entity will become a table in your database.
