Question

1. Define or briefly explain the following software development terminologies. Your answers should indicate the difference(s) between similar terminologies. Requirements Document Design Document

Answer 1

Answer: Firstly we need to discuss what is terminology.

Terminology: Terminology is basically a description of terms and it is generally, work or a document that consists of all the technical terms which are used in some field or some project. Now, what is software development terminologies.

Software Development Terminology: Software Development Terminology is a work or document that contains all the technical terms that are to be used while developing software. Now we are going to discuss Requirements Document Design Document in software development topologies.

Requirements Document: It is also known as the Software Requirement Specification report. It mainly includes:

1)Requirements Document in software development includes the whole description of the software that is going to be developed.

2)Requirements documents define what software is going to do and how software is able to do.

3)It identifies the qualities, features, and behavior of the software.

4)It describes the functionality of the system.

5)Requirements Document mainly defines the requirements for the development of software. It mainly includes the Functional, Non-Functional Requirements, and External Interface Requirements.

6) It also includes the software and hardware requirements of the software to be developed.

7)Good Requirement Document helps in developing the correct software.

Design Document: It is also known as Software Design Specification. After Requirements Document, Design Document is also very important in software development. The design document includes:

1)It includes the whole design and overview of the software that is going to be developed.

2)It is considered as the blueprint of the system.

3)It includes detailed information in the form of use case diagram and models which are explained in a manner that anyone who understands the problem can go ahead and start developing the software without any delay.

4) It gives the solution to the given problem.

5)It includes declarations and descriptions.

Some key differences between the Requirements Document and Design Document are:

1) Requirements Document defines the requirements and the Design Document defines the whole design of the software.

2) Requirements Document defines the problem and the Design Document provides a solution to the problem.

3) Requirements Document defines the functional, non-functional, hardware, and software requirements and the Design Document explains the physical and logical design element.

4) Requirements Document is the first part of software development and Design Document is the second part because after understanding what to do and after understanding all the requirements then the design is made.

5)By studying Design Document a person cannot start developing the software, It is necessary to understand the problem that is defined in the Requirements Document.

So above are the explanation of Requirements Document, Design Document, and key differences between them.
