ABSTRACT
An architecture is a deliberate and holistic design. Architectures are used in information technology to provide benets of synergy between the various components and layers of technology. In the absence of an architecture, an implementation of technology will be of necessity ad hoc. is implementation may meet a specic narrow set of requirements but may fail to interoperate with other deployed technologies, or worse, require duplication of components already implemented but incompatible with this specic technology.
