...Assignment 1 – UML What is UML? UML stands for Unified Modeling Language. It is a tool created by three renowned computer scientists; James Rumbaugh, Grady Booch and Ivar Jacobson between the years 1994 to 1996. It began as an attempt to combine all the good points from all the current modelling systems into one system that was coherent and better understood. These three men joined their ideas up at the Rational Software Corporation and evolved it into what it is known as today. I would describe UML to be a type of structure. It is used by large business applications and companies in order to provide a standard way for them to look at the design of the system that they are using. The system that these companies and businesses use must be designed...

...LOVELY PROFESSIONAL UNIVERSITY TERM PAPER ON Extending UML to Support Domain Analysis SUBMITTED TO:- SUBMITTED BY:- Mr. SANDEEP SINGH AKANSHU KUMAR Reg No:-11112286 ROLL No:- A21 SECTION:- K1107 Abstract:- The process of modelling and developing commonality and variability for system families should be supported by suitable methods and notations. The object-oriented methods and their notations, which are used at present, focus on the development of a single system at a time. In this paper we analyse feature models as a representation of the common parts and variants contained in a system family, and propose using a feature diagram as a basic representation of commonality, variability and dependencies. We examine various approaches to customizing the standard modelling language UML to model system families and propose how to extend the UML for the purposes of modelling variants in object-oriented analysis and design techniques. We recommend the use of UML standard lightweight extensibility mechanisms (stereotypes combined with tagged values) without changing the UML metamodel. This enables us to join the advantages of feature models with UML and provides the traceability of a concept throughout system...

...MDA and Analysis of Web Applications Behzad Bordbar and Kyriakos Anastasakis School of Computer Science, University of Birmingham, Birmingham, B15 2TT, UK {B.Bordbar,K.Anastasakis}@cs.bham.ac.uk Abstract. Enterprise systems are mission critical. As a result, ensuring their correctness is of primary concern. This paper aids to the analysis of Web Applications, focusing on the aspects related to the interaction of business logic and Web browsers. The method adopted is based on the Model Driven Architecture. First, the Platform Independent Model of Web Applications is refined to create a new model called Abstract Description of Interaction (ADI). An ADI is a UML class diagram annotated with OCL statements to represent an abstraction of the interaction between the thin client and the business logic. Secondly, the ADI model is automatically transferred to an Alloy model and analysed using the Alloy Analyser. 1 Introduction Over the past two decades Web Applications have become increasingly vital, affecting almost all aspects of our daily life such as banking, retail, information gathering, entertainment and learning. Such applications are mostly mission critical [1]. Hence, ensuring the correctness of the specification and implementation is a primary concern and has received considerable attention [2–4]. To analyse these systems, it is important to create a formal model. For example, [2] uses µ-calculus to represent the model, while [3] makes use of a variant of automata...

...Comments/Suggestions: CPT 125 Pre-Requisite: Completion of 1st Year Courses Introduction: Systems Design is a central part of systems development. It comprises the process of turning a set of user requirements into an implementable system and encompasses various activities to achieve this end. Alternative models are challenging the traditional systems development life cycle. Alongside this, two approaches to systems development are emerging: the traditional structured approach; and the object oriented approach. The systems design activity will be studied in the context of these trends. Students should make themselves familiar with at least one traditional approach (e.g. SSADM) and one object oriented approach (e.g. UML). Aims: To understand the role of systems design within various systems development life cycles To develop awareness of the different approaches that may be taken to systems design To understand and apply the tools and techniques that are currently used by systems designers Formatted: Superscript Objectives: Describe different life cycle models and explain the contribution of systems design within them Discuss various systems development approaches and explain their strengths and weaknesses 1 30/09/1123/09/10 Evaluate the tools and techniques that may be used by a system designer in a given context Use appropriate methods to produce a system design for a given scenario Provide suitable systems documentation for a design Discuss the CASE...

...used to generate, collect, organize, store, retrieve, and disseminate information. Specific IS used to manage student information is referred to as Student Information System (SIS). This research proposed a SIS for Saint Paul’s Academy High School (SPAHS) to address its problems with regard to managing student information which are in enormous amount of paper, documents or records filed in folders and stored in filing cabinets. Considering that information is a set or collection of data, with the manual information system approach, generating information suffers difficulties. After identifying the problem of SPAHS, a system architecture of the proposed SIS was established. The system architecture used a three tiered pattern and Unified Modeling Language (UML) was used to present the different views of the systems architecture. Functionalities include tracking all the details of a student from the day one to the end of the students stay in the school which can be used for all reporting purpose, tracking of attendance, progress in the subject, completed school years, project or any other assignment details, final exam result and all these will be available through a secure, online interface embedded in the school’s website. It will also have faculty details, batch execution details, students’ details in all aspects, the various academic notifications to the staff, students and parents updated by the administrator. Different reports and queries can be generated based on vast options...

...The process of asset management in universities does not utilise good information system. Many processes are still done manually and not integrated automatically using the system. Furthermore, the existing system is not ideally applied and causes it to run improperly, which obstructs its implementation. Therefore, the purpose of this study development is to solve problems faced by universities using business process re-engineering to gain significant improvements. The process of managing assets and repairs mapped and analyzed using the unified modeling language (UML). There are up to 3 alternatives and 2 scenarios in each procedures during the making. The result of this observation is a new design process simulated using iGrafx to examine the...

...5046 COMP Object Orientated Software Development EDepot System OOAD Outline of Problem In this assignment I have been asked to employ an Object Orientated Analysis & Design (OOAD) process in designing an eDepot System from a requirements document and use Unified Modelling Language (UML) to diagrammatically model the eDepot systems functionality. For this there will be 10 sections which I have been asked to produce and for each section I will complete the task asked for each. The information about the eDepot system in each section will be: 1) UML Use Case Diagram 2) List the Nouns from the Requirements Document 3) Revised list of Nouns that specify Candidate Classes 4) UML Class Diagram 5) Identification of Class Attributes 6) UML State Diagram 7) UML Activity Diagram 8) Identify Class Operations 9) UML Communication Diagram 10) UML Sequence Diagram Requirements Document In this document I have been told that the requirements of the eDepot system is that it is designed to manage a collection of Heavy Goods Vehicle depots for a haulage company. Associated with each depot will be a collection of vehicles, drivers and a depot manager who is responsible for organising a work schedule between different vehicles and drivers. The different type of vehicles available are trucks and tankers which share common attributes such as vehicle make, model, registration number and service history. There some attributes which are unique to one of the two types of vehicles...
