Definition

A column is a specific piece of information associated with a data entity in a database. It represents a single data point or property and is usually equivalent to an attribute. When creating a class, it's attributes become columns in a database table.

For example:

  • In a customer data entity, columns might include CustomerID, Name, Email, and Phone.
  • In a product data entity, columns might include ProductID, Name, Price, and Category.

Customization

In model-driven apps, you can customize columns (attributes) by defining their data type, validation rules, and display format.

Columns can be added, modified, or removed based on the specific requirements of your application.

Columns (fields or attributes) play a vital role in defining the structure and properties of data entities within a model-driven development environment.
