Introduction

In the EdoAbarca/it-ticket project, an IT ticketing system, developers frequently encounter the need to represent data that has a limited, predefined set of values. Think of a ticket's status (Open, In Progress, Resolved) or its priority (Low, Medium, High). Choosing the right data type for such fields is crucial for maintaining data integrity and application robustness.

Ever found yourself debating the best way to define a field with a limited, predefined set of values in your database? It's a common scenario, and the choice has significant implications for data integrity and application logic.

In the it-ticket project, an internal system for managing support tickets, defining the status of a ticket is a critical design decision.
