The Traditional Approach

  • The traditional approach to data management is whereby separate data files are created and stored for each application program.
  • For example customer records are often maintained in separate files, with each relating to a specific purpose in the company such as shipping or billing.
  • There are several flaws with the traditional approach they include:
    1. Data redundancy: duplication of data in separate files
    2. Data integrity: the degree to which the data in any one file is accurate
    3. Program dependence: concept where data for one application can be incompatible with another program.
