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.
