Primary objective of this case study is to analysis on the Application Architecture. With information systems Applications architecture is one of several architecture domains in which form the pillars of enterprise architecture or even solution architecture. Be aware that the term “application architecture” is frequently used for the interior structure of a software, for its application modularisation. Applications architecture would be the science and skill of ensuring the suite of applications being employed by an organization to generate the composite structure is scalable, dependable, available and feasible. This case study major focus to analyze: draw physical data flow diagrams for an information system’s architecture and processes.
