(1) Analysis: the second phase of the SDLC in which system requirements are studied and structured.
(2) Application Software: Computer software designed to support organizational functions or processes.
(3) Computer aided software engineering (CASE) tools: systems development methodologies created to radically decrease the time needed to design and implement information systems. This methodology relies on extensive user involvement, prototyping, integrated CASE tools and code.
(4) Design: the third phase of the SDLC in which the descriptions of the recommended solution in converted into logical and physical system specifications.
(5) Implementation: the fourth phase of the SDLC in which the information system is coded, tested, installed, and supported in the org.
(6) Information system analyses and design: the complex organizational process whereby computer-based information systems are developed and maintained.
(7) Inheritance: the property that occurs when entity types or object classes are arranged in a hierarchy and each entity type or object class assumes the attributes and methods of its ancestors; that is, those higher up in the hierarchy. The property allows new but related classes to be deirved from existing classes.
(8) Logical design: the part of the design phase of the SDLC in which all function features of the system chosen for development are described independently of any computer platform.
(9) Maintenance: the final phase of the SDLC in which an information system is systematically repaired and improved.
(10) Object: a structure that encapsulates attributes and the method that operate on those attribute. It 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. (11) Object class: a logical grouping of objects that have the same(or similar) attributes and behaviors.
(12) Object oriented analysis and design(OOAD): systems development methodologies and techniques based on objects rather than data or process.
(13) Physical design: the part of the design phase of the SDLC in which the logical specification of the system from logical design are transformed into technology-specific detail from which all programming and system construction can be accomplished.
(14) Planning: the first phase of the SDLC in which an organization's total information systems needs are identified, analyzed, prioritized, and arranged.
(15) Rapid Application Development: software tools that provide automated support for same portion of the system development process
(16) Rational Unified process(RAD): an object-oriented systems development methodology. This methodology establishes four phases of development, each of which is organized into number of separate iteration: inception, elaboration, construction and transition.
(17) System Analyst: the organizational role must responsible for the analysis and design of information systems.
(18) System development life cycle(SDLC): the traditional methodology used to develop, maintain and replace information systems.
(19)Systems development methodology: a standard process followed in an organization to conduct all the steps necessary to analyze, design, implement and maintain information systems.
