2.1 Information System 2.1.1 History of Information Systems The study of information systems‚ originated as a sub-discipline of computer science‚ in an attempt to understand and rationalize the management of technology within organizations. It has matured into a major field of management that is increasingly being emphasized as an important area of research in management studies‚ and is taught at all major universities and business schools in the world. Information technology is a

Architectural Modeling i.Component Diagrams ii.Deployment Diagrams Introduction In late 1960‘s people were concentrating on Procedure Oriented Languages such as COBOL‚ FORTRAN‚ PASCAL…etc. Later on they preferred Object Oriented Languages. In the middle of 1970-80 three Scientists named as BOOCH‚ RUMBAUGH and JACOBSON found a new language named as Unified Modeling

technique we propose is based on the observation that one of the forms of requirements engineering‚ the use case based requirements engineering [3‚ 4‚ 12‚ 10]‚ bears much resemblance to business process modeling. The resemblance between use case based requirements engineering and business process modeling becomes obvious when inspecting the following definitions of use case and business process. According to Jacobson [10] a UML use case: ’... specifies a sequence of actions‚ including variants‚

• Conceptual Modeling • Logical Modeling • Physical Modeling 2 Conceptual Modeling Conceptual-level concepts permit us to model the application world in terms that are independent of any particular data (logical) model. Conceptual models provide a framework for developing a 1 database schema from the top to the bottom in the process of a database design. This Section examines the entity-relationship model and the object-oriented model as representatives of conceptual modeling. The entity-relationship

System Modeling Models of the new system are used during requirements engineering to help explain the proposed requirements to other system stakeholders. Engineers use these models to discuss design proposals and to document the system for implementation. Lecture 1 In a model-driven engineering process‚ it is possible to generate a complete or partial system implementation from the system model.

software engineering‚ a class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system’s classes‚ their attributes‚ operations (or methods)‚ and the relationships among objects. • The class diagram is the main building block of object oriented modeling. • It is used both for general conceptual modeling of the systematic of the application‚ and for detailed modeling translating the models into programming code
