Question

What is the functionality of Data Cohesion in modules of projects ? Select one: a. None of them b. If a module is independent of data from other modules c. One module may be dependent on another module for data d. Both Option 1 and 2

Answer 1

Answer:

here is your answer

Explanation:

In computer programming, cohesion defines to the degree to which the elements of a module belong together. Thus, cohesion measures the strength of relationships between pieces of functionality within a given module. For example, in highly cohesive systems, functionality is strongly related.

Answer 2

We need to select the correct option about the functionality of data cohesion in modules of projects.

Options:

a. None of them

b. If a module is independent of data from other modules c. One module may be dependent on another module for data

d. Both Option 1 and 2

Let's know about data cohesion,

Data cohesion:

Cohesion refers to the degree to which the elements inside the module belong together. In other words we can say that it is a measure of the strength of relationship between the methods and data of a class. If all the elements of the module are related to each other and work for a same purpose then we consider it as data cohesion.

let's check the options

b. If a module is independent of data from other modules.

Cohesion just defines the togetherness of the elements of a module. It never discusses about other modules. If a module is independent of data from other modules then the program said to have low coupling.

Option b is related to coupling concept. It won't tells about the functionality of data cohesion.

c. One module may be dependent on another module for data.

This refers to coupling concept as well. coupling is the dependency of different modules of a program.

Option c is related to coupling concept. It won't tells about the functionality of data cohesion.

So the correct option is a. None of the above. None of the given options relates to data cohesion.
