Structured Analysis

Structured analysis is a development method for the analysis of existing manual or automated systems, leading to the development of specifications for a new or modified system. The underlying objective in structured analysis is to organise the tasks associated with requirements determination to provide an accurate and complete understanding of a current situation.

The word structure in structured analysis means:

1.The method attempts to structure the requirements determination process, beginning with documentation of the existing system.

2.The process is organised in such a way that it attempts to include all relevant details that describe the current system.

3. It is easy to verify when relevant details have been omitted.

4. The identification of requirements will be similar among individual analysts and will include the best solutions and strategies for systems development opportunities.

5. The working papers produced to document the existing and proposed systems are effective communication devices.

This method of analysis has become synonymous with data flow analysis which provides a tool for documenting an existing system and determining information requirements in a structured manner.

What is DFD ? or What is Data Flow Diagram?

A data-flow diagram ( DFD ) is a graphical representation of the "flow" of data through an information system. DFDs can also be used for the visualization of data processing ( structured design ). On a DFD , data items flow from an external data source or an internal data store to an internal data store or an external data sink, via an internal process . A DFD provides no information about the timing or ordering of processes, or about whether processes will operate in sequence or in parallel. It is therefore quite different from a flowchart, which shows the flow of control through an algorithm, allowing a reader to determine what operations will be performed, in what order, and under what circumstances, but not what kinds of data will be input to and output from the system, nor where the data will come from and go to, nor where the data will be stored (all of which are shown on a DFD ). ...

Rules for Stopping the Decomposition Process in DFD

Rules for Stopping the Decomposition Process in DFD (1) when you have reduced each process to a single decision or calculation or to a single database operation;  (2) when each data store represents data about a single entity;  (3) when the system user does not care to see any more detail or when you and other analysts have documented sufficient detail to do subsequent systems development tasks;  (4) when every data flow does not need to be split further to show that different data are handled in different ways;  (5) when you believe that you have shown each business form or transaction, computer on-line display, and report as a single data flow;  (6) when you believe there is a separate process for each choice on all lowest-level menu options for the system.
