System Analysis and Design
1) Describe each phase of SDLC briefly and concisely, use bulleting format.
Phases of Software Development Life Cycle (SDLC):
· System study/Initial Investigation - data gathering and inetrviewing techniques - includes information and exhibits
· Feasibility study - Establishes a high-level view of the intended project and determines its goals.
· System analysis/General design - Defines project goals into defined functions and operation of the intended application. Analyzes end-user information needs.
· System design/Detailed design - Describes desired features and operations in detail, including screen layouts, business rules, process diagrams, pseudocode and other documentation.
· Implementation - The real code is written here.
· System Audit – an evaluation should be made to determine whether the system meets the objectives started in the general design report.
2) Describe each system requirement briefly and concisely, use bulleting format.
System Requirements:
· User's requirements - these could be features, interfaces or functions demanded by the client. Software engineers are required to meet all the user's requirements for a successful software development approach.
· Technical Requirements - a technical requirement pertains to the technical aspects that your system must fulfill, such as perfomance- related issues, reliability issues and availability issues. 3) Following are the different methods in gathering data for the system development. Describe each briefly and concisely, use bulleting format.
· Investigation Methods - the act or process of investigating. A detailed inquiry or systematic examination. · Survey Methods - the survey is a non-experimental, descriptive research method. Surveys can be useful when a researcher wants to collect data on phenomena that cannot be directly observed (such as opinions on library services). · Observation Methods - is a
