Analysis and design of information system,[object Object]
introduction,[object Object],Information Systems Analysis and Design,[object Object],Complex organizational process whereby computer-based information systems are developed and maintained,[object Object]
System  development life cycle,[object Object],Traditional methodology for developing, maintaining, and replacing information systems,[object Object],Phases in SDLC:,[object Object],Planning,[object Object],Analysis,[object Object],Design,[object Object],Implementation,[object Object],Maintenance,[object Object]
The system development life cycle,[object Object]
The planning phase,[object Object],Identify, analyze, prioritize, and arrange IS needs,[object Object]
introduction,[object Object],ANALYSIS,[object Object],Analysis as ‘the breaking up of any whole so as to find out their nature, function etc.,[object Object],Analysis gives the conceptual understanding of a system from the logical point of view by detailing its functionality.,[object Object]
Study and structure system requirements,[object Object]
design,[object Object],Design as ’to make preliminary sketches of; to sketch a pattern or outline for; to plan and carry out especially by artistic arrangement or in a skilful way.’,[object Object],Designing gives us the blueprint on the basis of which the actual system is developed ,[object Object]
Analysis concepts and principles,[object Object],Requirement analysis,[object Object],Requirement analysis is a formal process of interacting with a client to understand and then put in a formal document the requirement of the client.,[object Object],While initiating the process of requirement elicitation and analysis, some key issues must be understood so that analysis is easier, they are:,[object Object],The key people driving the request. This will help them to focus their information gathering activity.,[object Object]
Conti….,[object Object],The key people who will use the system.,[object Object],The financial benefit.,[object Object],What accounting to user is a good solution?,[object Object],What is the problem that system will address?,[object Object]
Analysis Principles,[object Object],The domain of information in which the problem operates has to be appreciated.,[object Object],The key functions of the system have to be defined.,[object Object],System must be modular. This is required to help create the system in a faster way.,[object Object],System has to be defined in abstract term. This helps reduce complexity.,[object Object],The ambiguity in the system must be reduced to enable designer to focus on the outcome clearly.,[object Object]
System requirement specification,[object Object],Information description :  where the detailed information description is given.,[object Object],Functional description : where the functionality required from the system is given.,[object Object],Validation description : this is the data validation and business rule description required in the system.,[object Object]
Design principle,[object Object],It should have an overall macro view of the system rather than a tunnel view,[object Object],The design process should be logical.,[object Object],The design should reinvent the wheel.,[object Object],The design should be a very close abstraction of the problem.,[object Object],The design should be uniform and integrated,[object Object],The design should be structured,[object Object],The design should be reviewed on a real-time basis to minimize errors.,[object Object]
Design concept,[object Object],Abstraction,[object Object],Procedural abstraction,[object Object],Data abstraction,[object Object],Control abstraction,[object Object],Refinement,[object Object],Modularity,[object Object]
abstraction,[object Object],Abstraction is the conceptualization of an issue or problem or entity in terms of some level of generalization without regarding to irrelevant low-level details.,[object Object],Procedural abstraction : it is a named collection of several sequential procedural steps.,[object Object],Data abstraction : this is name of a set of data that defines of an object.,[object Object],Control abstraction : this is a named control mechanism, which has several steps.,[object Object]
refinement,[object Object],Refinement helps the designer in elaborating the system and bringing-out lower-level details as the design progress.,[object Object],This is a top- down design strategy in which design is refined after each successive step.,[object Object]
modularity,[object Object],It helps the designer to compartmentalize the design into functional compartments as the entire system can be conceived to be composed of a set of modules, each having its own special feature and functionality rather than a monolithic entity.,[object Object],Modularity helps the designer to comprehend the system better.,[object Object],Effective modular design in general reduces the complexity of the system by dividing system into easily understandable modules.,[object Object]
Tool for design,[object Object],Data flow diagram(DFD),[object Object],Data dictionary(DD),[object Object]
Data flow diagram(DFD),[object Object],[object Object]
It can be two types – Logical data flow diagram and Physical data flow diagramLogical data flow diagram deals with the functional views of the system.,[object Object]
	Entity is represented.,[object Object],Curve like represents information flow from one entity (or) process (or) data store to another,[object Object],Two parallel lines represent data store.,[object Object],a process is represented by a circle.,[object Object]
SDLC Design Phase,[object Object],Logical design: functional features described independently of computer platform,[object Object],Convert recommended solution to system specifications,[object Object],Physical design: logical specifications transformed to technology-specific details,[object Object]
Data dictionary(DD),[object Object],[object Object]
It is the source document for specifications of all inputs, protocols, outputs, data structures, database structures, meta data and algorithm.,[object Object]
