Data Integrity

Visual Studio .NET 2003

Data integrity is about the actual values that are stored and used in your application's data structures. Your application must exert deliberate control on every process that uses your data to ensure the continued correctness of the information.

You can ensure data integrity through the careful implementation of several key concepts, including:

  • Normalizing data.
  • Defining business rules.
  • Providing referential integrity.
  • Validating the data.

The following sections will acquaint you with some important ways you can ensure the integrity of your application's data.
