Designing a Chat Message Model

When building a chat application, messages, users, and rooms are core components. To handle these effectively, we need to design clear data models.

Data models define the structure of your information. This ensures consistency, makes data storage easier, and simplifies how different parts of your app interact.

Every chat app has users! The User Model defines what information we store about each participant.

Key properties typically include:

• ID: A unique identifier for each user.
• Username: A human-readable name.

We'll use a simple Java class to represent this model.
