Systems Analysis and Design Flashcards

Flashcards on Systems Analysis and Design

Computer Application (App)

A computer software program that executes on a computing device to carry out a specific function or set of related functions.

Information System

A set of interrelated computer components that collects, processes, stores, and provides as output the information needed to complete business tasks.

Systems Analysis

Those activities that enable a person to understand and specify what the new system should accomplish.

Systems Design

System development activities that enable a person to describe in detail how the resulting information system will actually be implemented.

Project

A planned undertaking that has a beginning and an end, and that produces some definite result

Systems Development Life Cycle (SDLC)

A framework that identifies all the activities required to research, build, deploy, and often maintain an information system.

System Development Process or Methodology

A set of comprehensive guidelines for carrying out all of the activities of each core process of the SDLC.

Agile Development

An information system development process that emphasizes flexibility and rapid response to anticipate new and changing requirements during development.

Iterative Development

An approach to system development in which the system is 'grown' piece by piece through multiple mini-projects called iterations.

Subsystem

An identifiable and partitioned portion of the overall system

To understand what the system must do and specify how the components are configured to provide the solution.

What is the purpose of systems analysis and design when developing information systems?

To define all the activities required to develop a new system. It provides a framework for the development process.

What is the purpose of the System Development Life Cycle (SDLC)?

1. Identify the problem or need and obtain approval to proceed. 2. Plan and monitor the project. 3. Discover and understand the details of the problem or the need. 4. Design the system components. 5. Build, test, and integrate system components. 6. Complete system tests and then deploy the solution.

What are the six core processes of the SDLC?

Flexibility and rapid response to anticipate new and changing requirements during development.

What are some characteristics of Agile methodologies?

To identify all of the tasks that must be done to complete a particular iteration and produce the defined deliverable.

What is the purpose of a Work Breakdown Structure?

To define the order of the work. It also helps to monitor the progress of the iteration and assign resources to tasks.

What is the purpose of a work sequence diagram?

To identify and list the functions that must be provided by the new system.

What is the purpose of a list of use cases?

To identify and list the information components that must be maintained by the new system.

What is the purpose of a table of classes or class diagram?

To document the use cases and the actors in a system or subsystem.

What is the purpose of a use case diagram?

To define the detailed processing steps of a use case.

What is the purpose of a workflow diagram?

To design the layout of a computer screen, including all the data elements required on the screen.

What is the purpose of sample screen layouts?

To define the details of the information requirements in preparation for building the database schema.

What is the purpose of a design class diagram?

It is the detailed database structure, used to build the database with MySql, Oracle, or SQLServer.

What is the purpose of the database schema?

To configure the overall solution system.

What is the purpose of the system architectural configuration diagram?

To define the individual components of a subsystem and identify how they relate to each other.

What is the purpose of the subsystem architectural design diagram?
