Enterprise Architecture is a generalised term, which refers to a number of architectural representations each based on a different viewpoint. The core representations being: the Business, the Information, the Application and the Technology architectures. Since the seminal work on Enterprise Architecture by John Zachman, first published in 1987, a number of architectural frameworks have been suggested e.g. TOGAF, RM-ODP, C4ISR, TEAF and FEAF. In the current study, this paper discusses the various architectural representations from various perspectives, and presents a basic model for the development of an enterprise architecture. Zachman framework is discussed in some detail and a brief overview of several other enterprise models is given. The emphasis is on information and data architectures. The objective is to promote understanding of enterprise architectures and to present enough appropriate background information so that it serves as a useful guidance for the large enterprises who wish to embark on the process of developing enterprise-wide information architectures.
