Modern Systems Analysis and Design
Terms in this set (20)
The second phase of the SDLC in which system requirements are studied and structured.
Computer software designed to support organizational functions or processes.
Computer-aided software engineering (CASE) tools.
Software tools that provide automated support for some portion of the systems development process.
The third phase of the SDLC in which the description of the recommended solution is converted into logical and then physical system specifications.
The forth phase of the SDLC in which the information system is coded, tested, installed, and supported in the organization.
Information systems analysis and design
The complex organizatinal process whereby computer-based information systems are developed and maintained.
The property that occurs when entity types or object classes are arranged in a hierachy and each entity type or object class assumes the attributes and methods of its ancestors, that is, those higher up in the hierarchy. Inheritance allows new but related classes to be derived from existing classes.
The part of the design phase of the SDLC in which all functional features of the system chosen for development in alalysis are described independently of any computer platform.
The final phase of the SDLC in which an information system is systematically repaired and improved.
A structure that encapsulates ( or packages) attributes and methods that operate on those attributes . An _______ is an abstraction of a real-world thing in which data and processes are placed together to model the structure and behavior of the real-world object.
A logical grouping of objects that have the same (or similar) attributes and behaviors (methods).
Object-oriented analysis and design (OOAD).
Systems development methodologies and techniques based on objects rather than data or processes.
The part of the design phase of the SDLC in which the logical specifications of the system from logical design are transformed into technology-specific details from which all programming and system construction can be accomplished.
The first phase of the SDLC in which an organization's total information system needs are identified, analyzed, prioritized, and arranged.
Rapid Application Development (RAD).
Systems development methodology created to radically decrease the time needed to design and implement information systems. _______ relies on extensive user involvement, prototyping, integrated CASE tools, and code generators.
Rational Unified Process (RUP).
An object-oriented systems development methodology. ________ establishes four phases of development; inception, elaboration, construction, and transition. Each phase is organized into a number of separate iterations.
Service-Oriented Architecture (SOA).
An approach to systems development based on building complete systems through assembling software components, each of which model generic business functions.
The organizational role most responsible for the analysis and design of informaton systems.
Systems development life cycle (SDLC).
The traditional methodology used to develop, maintain, and replace information systems.
Systems development methodology
A standard process followed in an organization to conduct all the steps necessary to analyze, design, implement and maintain information systems.
