Cohesion

Module Cohesion

• manner and degree to which the tasks performed by a single software module are related to one another [1, Sec. 3.625]
• in software design, a measure of the strength of association of the elements within a module [1, Sec. 3.625] [2, Sec. 2.1.4] cf. coupling

  Contains

• 7 types: coincidental, temporal, logical, sequential, procedural, communicational, and functional.

Common-environment Coupling

Common-envrionment Module Coupling

• type of coupling in which two software modules access a common data area [1, Sec. 3.654]

  Type of

• Module Coupling

Content Coupling

Content Module Coupling

• type of coupling in which some or all of the contents of one software module are included in the contents of another module [1, Sec. 3.816]

  Type of

• Module Coupling

Control Coupling

Control Module Coupling

• type of coupling in which one software module communicates information to another module for the explicit purpose of influencing the latter module’s execution [1, Sec. 3.853]

  Type of

• Module Coupling

Coupling

Module Coupling

• manner and degree of interdependence between software modules [1, Sec. 3.919]
• strength of the relationships between modules [1, Sec. 3.919)
• measure of how closely connected two routines or modules are [1, Sec. 3.919]
• in software design, a measure of the interdependence among modules in a computer program [1, Sec. 3.919] [2, Sec. 2.1.4]

  Contains

• 6 types: pathological, control, hybrid, data, content, common-environment
