A description of the system’s architecture in terms of data‚ processes‚ interfaces‚ and network are also included in this phase and will be addressed in this portion of the paper. Finally‚ a physical data flow diagram will be included to show how the system will take in data and deliver and expected output. Application Architecture and Process Design Application architecture is the process of defining a structured

1. What is documentation? Why do accountants need to understand documentation? ------------------------------------------------- Documentation refers to a set of documents and models‚ such as narratives‚ data flow models‚ flowcharts‚ and other written materials that explain a how a system works. Documentation tools are important‚ because: -At minimum‚ you must be able to read documentation to determine how the system works. -You may be required to evaluate internal control systems documentation

While designing the DFD’s we increase the level of detail with each level. At each level the process divides into sub-processes until indivisible sub-processes are reached. Here is an example.

current system indicated two main problems. First‚ the current system is extremely fragmented‚ actually consisting of several different systems and data stores‚ which lead to efficiency problems as well as data integrity issues. Second‚ alumni involvement with ICC was lacking‚ which resulted partly from ICC’s inability to harness and organize their current data stores.
