Modeling Language (UML) is an "object modeling and specification language used in software engineering ("Unified Modeling Language"‚ 2005)." It was created to consolidate and standardize 50 different modeling languages that were used by many businesses. The project request to normalize the modeling languages was made by Object Management Group (OMG) and answered by James Rambaugh‚ Grady Booch‚ and Ivar Jacobson. In addition to Rambaugh‚ Booch‚ and Jacobson‚ a team called the UML Partners‚ which included

problem‚ the cheaper it is to fix ‚ otherwise to detect the errors in the project is very expensive or complicated . This law is applicable from midrange systems. Example: City Council – Pay Roll System A city council developed a replacement payroll system believed that users had comprehensive knowledge of all the business requirements. But the current staff or IT team had participated in building the old system - they had no knowledge of how it was built. That leads

INTRODUCTION 1.1 Overview A management information system (MIS) is a system that provides information needed to manage organizations effectively. Management information systems are regarded to be a subset of the overall internal controls procedures in an organization‚ which cover the application of people‚ documents‚ technologies‚ and procedures used by management accountants to solve business problems such as costing a product‚ service or a business-wide strategy.

Meaning of Collaboration Diagram:- also called a communication diagram or interaction diagram‚ is an illustration of the relationships and interaction between entities or objects in the Unified Modelling Language (UML)‚ Collaboration diagrams resembled a flow chart that represent the roles‚ functionality and behaviour of

the heart of UML. It represents the core purposes of UML because it separates the design elements from the coding of the system. UML was set up as a standardized model to describe an object-oriented programming approach. Since classes are the building block of objects‚ class diagrams are the building blocks of UML. The diagramming components in a class diagram can represent the classes that will actually be programmed‚ the main objects‚ or the interaction between class and object. The UML shape library
