1) Data element- It is the smallest unit of data that cannot be meaningfully decomposed further. Example- Employee number and so on.
2) Data structure is a group of data elements forms a data structure.
3) Data Flows as well as Data Stores- data flows are data structures in motion whereas data stores are data structures at rest.
Subroutines Frequently, the similar piece of code must write over again in many dissimilar parts of a program. Instead of repeating the code every time it is required, there
This strategy includes testing the classes as they are integrated into the system. The traditional approach would test every operation separately as they are executed into a class.
What is software testing?
State about the Normal data- Test data - This is data which is valid/acceptable and has expected outcomes (for instance, if a date is being input the day must be in the rang
State the term- Code Coverage This is an analysis method that determines which parts of software have already been covered by test case suite and which are remaining.

What are the benefits of prototyping? i. Prototype serves as a basis for deriving system specification. ii. Design quality can be improved. iii. System can be maintained
Applicability: It is another significant characteristic of a model. The model should be judged by its degree of applicability across software products that change in size, structu
