Building a Finite State Machine with PostgreSQL
Finite State Machines (FSMs) are powerful tools for modeling workflows, processes, and business logic that involve a series of states and transitions. While FSMs are often implemented in application code, PostgreSQL’s advanced features—such as triggers, constraints, and procedural functions—make it possible to manage state transitions directly within the database.
In this upcoming blog series, we will discover how to build Finite State Machines (FSM) with PostgreSQL. The series will guide you through designing robust FSMs, enforcing valid transitions, and leveraging PostgreSQL’s advanced features—such as triggers, constraints, and procedural functions—to manage state transitions directly in the database. By the end of the series, you’ll see how PostgreSQL can serve as more than just a data store—it can be the engine that drives your application’s stateful logic.
