The primary objective of system analysis is to gather and analyze requirements from stakeholders to understand the needs and objectives of the system.

Use case analysis, data flow diagramming, and entity-relationship modeling are all common system analysis techniques used to gather and analyze requirements.

The purpose of a system design is to translate requirements into a technical solution, develop a detailed plan for implementing the system, and create a prototype of the system.

Object-oriented design, structured design, and agile development are all common system design techniques used to translate requirements into a technical solution.

The purpose of system testing is to verify that the system meets its requirements, identify and fix defects in the system, and ensure that the system is reliable and secure.

Unit testing, integration testing, and system testing are all common system testing techniques used to verify that the system meets its requirements.

The purpose of system maintenance is to keep the system up-to-date with changing requirements, fix defects in the system, and improve the performance and reliability of the system.

Software updates, hardware upgrades, and performance tuning are all common system maintenance techniques used to keep the system up-to-date with changing requirements, fix defects in the system, and improve the performance and reliability of the system.

System analysis is the process of gathering and analyzing requirements from stakeholders to understand the needs and objectives of the system, while system design is the process of translating these requirements into a technical solution.

The role of a system analyst is to gather and analyze requirements from stakeholders to understand the needs and objectives of the system.

The role of a system designer is to translate requirements into a technical solution and design and implement a system.

The role of a system tester is to test and evaluate a system to verify that it meets its requirements.

The role of a system maintainer is to maintain and update a system to keep it up-to-date with changing requirements, fix defects in the system, and improve the performance and reliability of the system.

A system is a collection of components that work together to achieve a common goal, such as a computer system, a business system, or a manufacturing system. A software application is a computer program that performs a specific task, such as a word processor, a spreadsheet, or a web browser.

System analysis and design is important because it helps to ensure that the system meets the needs of the stakeholders, reduces the risk of project failure, and improves the quality of the system.
