Can you explain what a ticket management system in a database is and how it works?

A ticket management system in a database is an application or service that stores and processes user or client inquiries (tickets). A ticket typically contains information about a problem, request, or task, as well as its status.

How it works:

1. The user creates a ticket by filling out a form describing the problem.
2. The ticket is saved in the database with a unique identifier, creation date, status (e.g., "new", "in progress", "closed"), and other metadata.
3. Support staff or developers access the tickets, can change their status, add comments, and assign responsible persons.
4. All changes are recorded in the database, allowing the history of the inquiry to be tracked.

Example of a ticket table structure in SQL:

CREATE TABLE tickets (
  id SERIAL PRIMARY KEY,
  title VARCHAR(255) NOT NULL,
  description TEXT,
  status VARCHAR(50) DEFAULT 'new',
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
  updated_at TIMESTAMP,
  assigned_to INT -- Employee ID
);

Thus, the system helps organize work with requests, monitor their execution, and store interaction history.
