Since Stephen Spewak's [[Enterprise Architecture Planning]] (EAP) in 1993, and perhaps before then, it has been normal to divide enterprises architecture into four [[architecture ___domain]]s.

=== Layers of the enterprise architecture ===

For many years, it has been common to regard the architecture domains as layers, with the idea that each layer contains components that execute processes and offer services to the layer above. This way of looking at the architecture domains was evident in TOGAF v1 (1996), which encapsulated the technology component layer behind the platform services defined in the "Technical Reference Model" - very much according to the philosophy of TAFIM and POSIX.
