![]() In data coupling, the components are independent to each other and communicating through data. Data Coupling: If the dependency between the modules is based on the fact that they communicate by passing only data, then the modules are said to be data coupled.No need to write it again and again.Ĭoupling: Coupling is the measure of the degree of interdependence between the modules. A module can be used many times as their requirements.There are many advantages of Modularization in software engineering. Modularization: Modularization is the process of dividing a software system into multiple independent modules where each module works independently. Functionality and hierarchy of software component.Describes the functionality of the system.Detail explaination about system characteristics.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.
