Abstract Factory Pattern (Go)

What is Abstract Factory?

Abstract Factory is a creational design pattern. It provides an interface to create families of related objects without specifying their concrete types.

You use this pattern when:

• You have multiple product types that must work together
• You want to switch entire families of objects at once
• You want to avoid mixing incompatible objects

  • Transaction
• UI toolkits (Windows / Mac)
  • Button
  • Checkbox
• Cloud providers (AWS / GCP)
  • Storage
  • Queue
  • Logger

Example in this project

We support two databases:

• MySQL
• PostgreSQL

Each database provides:

• Connection
• Query builder

The factory creates matching components together.
