Data Model

Definition

The structure that defines how data is organized, stored, and related.

In Plain English

A data model is like an architect's blueprint—it defines the structure before building.

Real-World Example

Your data model might specify that Orders belong to Customers, and each Order contains multiple Products.

Why It Matters for Your Work

A good data model makes applications easier to build and maintain. A poor model causes ongoing problems.

Common Mistake

Not planning the data model before building. Changes to data structure are expensive later.
