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...
