Logical Cohesion: The elements are logically related and not functionally.Lots of different activities occur, all at init time.
#Cohesion and coupling in software engineering ppt code#
This cohesion contains the code for initializing all the parts of the system. A module connected with temporal cohesion all the tasks must be executed in the same time-span.

#Cohesion and coupling in software engineering ppt update#
Example- update record int the database and send it to the printer. Communicational Cohesion: Two elements operate on the same input data or contribute towards the same output data.It occurs naturally in functional programming languages.

Second is Technical Design that allows the system builders to understand the actual hardware and software needed to solve customer’s problem. First part is Conceptual Design that tells the customer what the system will do. The output of the design phase is Sofware Design Document (SDD).īasically, design is a two-part iterative process. Introduction: The purpose of Design phase in the Software Development Life Cycle is to produce a solution to a problem given in the SRS(Software Requirement Specification) document.
