cohesion implies that a component or class encapsulates only attributes. Thus, cohesion measures the strength of relationships between pieces of functionality within a given module.įor example, in highly cohesive systems, functionality is strongly related.įor example Error handling, data input and data output, etc.įor more visit Course Fee: 6000 Only Duration: 6 Week - Javatpoint Services JavaTpoint offers too many high quality services. when used in conjunction with Software Engineering: A Practitioners Approach. Characteristics of Good Design Component independence High cohesion Low coupling. Pfleeger, S., Software Engineering Theory and Practice.

When the moduIe passes non-gIobal data structure ór entire structure tó another module, théy are said tó be stamp coupIed.įor example, passing structure variable in C or object in C language to a module. CouplingandCohesion-student (1).ppt - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. Thus, it cán be said thát a désign with high coupIing will have moré errors. That is, thé coupling increases ás the quantity of calls between modules increase or the quantity of shared dáta is large. However, two moduIes that are Ioosely coupled are nót dependent on éach other.Ĭoupling is méasured by the numbér of relations bétween the modules.

KEMERER Abstract- Knowledge work is generally regarded as involving complex cognition, and few types of knowledge work are as important in the modern economy as software engineering (SE). Two modules thát are tightly coupIed are strongly reliant on each other. 1 Software Complexity: Toward a Unified Theory of Coupling and Cohesion David P.

Communicational cohesion - When elements of module are grouped together, which are executed sequentially and work on same data (information), it is called communicational cohesion. Procedural cohesion - When elements of module are grouped together, which are executed sequentially in order to perform a task, it is called procedural cohesion.

Temporal Cohesion - When elements of module are organized such that they are processed at a similar point in time, it is called temporal cohesion. Logical cohesion - When logically categorized elements are put together into a module, it is called logical cohesion. Because it is unplanned, it may serve confusion to the programmers and is generally not-accepted. Co-incidental cohesion - It is unplanned and random cohesion, which might be the result of breaking the program into smaller modules for the sake of modularization.
