R/3 client/server applications run inside multitiered systems, where software components are arranged in tiers. Each R/3 implementation is made up of three layers, as follows:
  • Database layer: Contains an application database and database management system (DMS)
  • Application layer: All R/3 system application programs are run on the application layer, which contains application program components.
  • Presentation layer: Contains the software component that comprises the graphical user interface (GUI) between R/3 systems and users.
