development process. UML DIAGRAMS ARE: USE CASE DIAGRAM SEQUENCE DIAGRAM CLASS DIAGRAM USE CASE DIAGRAM: A Use case is a set of scenario that describes an interaction between user and a system. A Use case diagram displays the relationship among Actors and Use cases. The two main components of Use case diagrams are: 1. Use cases Functions 2. Actors-User SEQUENCE DIAGRAM: It describes the behavior of a system by viewing the interaction between the system and its environment. Sequence diagram has two dimensions:

UML (Unified Modeling Language) What Is UML? The Unified Modeling Language was originally developed at Rational Software but is now administered by the Object Management Group . It is a modelling syntax aimed primarily at creating models of software-based systems‚ but can be used in a number of areas. UML is a very important part of developing object oriented software and the software development process. UML uses mostly graphical notations to express the design of software projects. Using

Cao‚ 2001). In addition to this‚ UML includes modeling diagrams that present the static and dynamic view of a system (Siau & Cao‚ 2001). These modeling diagrams are separated into three categories: structure diagrams‚ behavior diagrams‚ and interaction diagrams. Structure diagrams include class‚ component‚ object‚ and deployment diagrams. A class diagram represents the "fundamental architecture of a system" ("Class Diagram"‚ 2005). The diagram consists of boxes that contain information on the different

visual modeling language that enables system builders to create blueprints that capture their visions in a standard‚ easy-to-understand way‚ and provides a mechanism to effectively share and Communicate these visions with others. The purpose of the diagrams is to present multiple views of a system; this set of multiple views is called a model. UML model describes what a system is supposed to do. It doesn’t tell how to implement the system. EXPERIMENT INDEX

DATA FLOW DIAGRAM - one of the most commonly used modeling tool which graphically represents a system as a network of processes‚ linked together through input and output flow lines and entities. Data flow Components ▪ Process - transformation of data flow into outgoing data flow. It may represent . . - whole system - subsystem - activity ▪ Data store - repository of data in the system It may represent . . . - computer file or

improved in order to make diagrams more readable. (For example‚ modeling logical flow in UML 1.x was complicated and at times impossible. Changes to the sequence diagram’s notation set in UML 2 have made vast improvements in modeling logic in sequences.)
