Functional and Non-Functional Requirements - (BCA / B.Tech)

Functional and non-functional requirements in Hindi | Functional and Non-Functional Requirements in Hindi:

In software development, functional and non-functional requirements play an important role in determining the direction of the design and development of any system.
It is necessary to clearly understand both these types of requirements so that the software system can be built with its full functionality and quality.

Both functional and non-functional requirements are important for the successful creation of a software system and for user satisfaction. Functional requirements ensure that the system meets the user's expectations and performs the tasks that are expected of it,
while non-functional requirements ensure that the system is of high quality, secure, and enhances the user experience. The right balance of both these types of requirements helps in bringing the software to its full potential.

Functional Requirements in Hindi | Functional Requirements:

Functional requirements are those features that define the operation of a software system. They tell what the system should do, i.e., the details of the system's functionality.
This includes the tasks to be performed by the user, inputs, outputs, and data exchange between different components of the system, etc.

Example:

Suppose a banking application is being developed, then some of its functional requirements can be as follows:

User login and registration: Providing the facility for users to log in and for new users to register.
Money transfer: Giving the user the facility to transfer funds from one account to another.
Account balance check: Facility for the user to get information about their account balance.
Statement generation: Facility to download details of past transactions.

Features of Functional Requirements in Hindi | Main components of functional requirements:

Data input and output: What the system will get in input and what it will have to give in output.
Processing: How the system will process the input data.
User interaction: How the user will interact with the system.

Clear functionality: These requirements clarify what tasks the system has to perform.
User expectations: Defining functional requirements helps to correctly identify user expectations.
Correct development: This helps developers to work in the right direction.

Non-Functional Requirements in Hindi | Non-Functional Requirements:

Non-functional requirements are related to the quality and performance of the system. These requirements define how the system should work, i.e., features related to the quality, performance, security, and user experience of the system.
Non-functional requirements ensure the reliability of the system and user satisfaction.

Example:

The non-functional requirements of a banking application can be as follows:

Performance: The load time of the application should not be more than 3 seconds.
Security: All sensitive information of the user (such as passwords) should be securely encrypted.
Availability: The system should be available 24/7.
Scalability: The system should be built in such a way that it can handle thousands of users at a time.
User-Friendly Interface: The interface of the application should be easy to use and attractive.

Features of Non-Functional Requirements in Hindi | Main components of non-functional requirements:

Performance: The speed and response time of the system.
Security: Data privacy, encryption, access control.
Portability: The ability to use the system on different platforms.
Maintainability: The process of improving and fixing bugs in the system.
Scalability: The ability to scale the system according to the growing number of users.

Importance of Non-Functional Requirements in Hindi | Importance of non-functional requirements:

Improving system quality: Non-functional requirements ensure that the system is of high quality.
User satisfaction: The user experience depends on these requirements.
Competition in the market: A high-quality product helps in staying competitive in the market.
