Towards a Holistic Architecture Platform

This paper defines a three-dimensional architectural framework, named Technology and Information Platform (TIP), to effectively handle the architecture complexity and manage the architectural assets of enterprise information systems in a service-oriented paradigm. This comprehensive model is composed of a Generic Architecture Stack (GAS) comprising a stack of architecture layers, and the contextual spectrums consisting of the Process, Abstraction, Latitude, and Maturity (PALM) dimensions. The GAS stack contains seven interrelated layers: Enterprise Business, Enterprise Technical, Cross Business-line, Channel Specific, Application Solution, Aspect-Oriented, and Component Technology Architectures. A concept of Meso-Architecture ision, Latitude, and Maturity (PALM) dimensions. The GAS stack contains seven interrelated layers: Enterprise Business, Enterprise Technical, Cross Business-line, Channel Specific, Application Solution, Aspect-Oriented, and Component Technology Architectures. A concept of Meso-Architecture is proposed in this work to facilitate the serviceand channel-level architecture modeling in a service-oriented computing style. The key practitioners responsible for these architectural models in the platform are also specified in the context. Part of this pyramid blueprint has been extensively utilized in one form or another to design various IT solutions in different industries such as finance, telecommunications, and government.
