ANALYSIS CONCEPTS & PRINCIPLES The information domain must be represented and understood. The function must be defined. The behavior of software must be represented. Models that depict information, function, and behavior must be segregated in a manner that uncovers details in a layered manner. The analysis process must move from essential information to implementation details. FUNCTIONAL MODELLING : It provides the outline that what the system is supposed to do. It does not describe what is the need o evaluation of data, when they are evaluated, and how they are evaluated apart from all it only represents the origin of data values. It describes the function of the internal process with the help of DFD (Data Flow Diagram). INFORMATION FLOW MODELING : It distinguishes the discrete processing stage within the process, and describes how information flows through the system. BEHAVIOR MODEL : It is specially designed to make us understand behavior and factors that influence the behavior ...

The analysis Model is a technical representation of the software. It acts as a link between system description and design model. DATA DICTIONARY: It is a repository that consists of a description of all data objects used or produced by the software. ENTITY RELATIONSHIP DIAGRAM (ERD): It depicts the related activities. The attributes of each object in the Entity Relationship Diagram can be described using data object description. DATA FLOW DIAGRAM (DFD): It depicts the functions that transform data flow and it also shows how data is transformed when moving from input to output. STATE TRANSITION DIAGRAM (STD): It shows various modes of behavior (states) of the system and also shows the transitions from one state to another state in the system. PROCESS SPECIFICATION: It stores the description of each function present in the Data Flow Diagram (DFD). It describes the input to a function, the algorithm, that is applied to the input, and the output, that is produced. CONTROL SPECIFICATION: It...
