13. 3-tier
Previous pageTable of contentsNext page
The purpose of 3-tier programming is to separate the 3 standard "layers" of an application: GUI, processes and data.
Therefore, an application will include 3 separate tiers:
  • a presentation layer,
  • an application layer,
  • a layer for accessing the data.
The reason for separating the layers is to simplify the maintenance and the future evolutions of the application. This provides better security because the access to the database is allowed via the Processes layer only. It also optimizes the teamwork and the multi-target development.
