Description The core strength of this subject is to analyse and model business objectives and critical requirements of software systems to be developed using object-oriented (OO) approaches. The system analysis is taken to greater depths within the context of Object Orientation. The Unified Modelling Language version 2.0 (notably use cases, user case diagrams, activity diagrams, class diagrams and sequence diagrams) is used as the modelling standard for creating OO models in the problem space. The subject also covers the rational unified process methodology and applications of design patterns for software development through practical case studies.

Assumed Knowledge

General understanding of what an information system is and how information systems development is undertaken and
• Introductory knowledge about system analysis and design, including
- basic problem solving experience in computerised information systems
- ability to derive systems requirements from problem definitions
- ability to produce system models using process, data, object and network modelling.
- understanding design and implementation issues include, (but may not be limited to), elementary database design, input, output and user interface design and prototyping.
• General knowledge on programming languages
- Understanding difference between procedure programming and object oriented programming
- Introductory knowledge of classes and objects and the class construction
- Introductory knowledge on object orientation, including encapsulation, inheritance.

Learning Outcomes

On successful completion of this subject, students should be able to:

Explain the theoretical fundamentals underpinning Object Oriented Analysis.
Identify Unified Modelling Language (UML) of the Object Management Group (OMG) for analysing software requirements,
Outline an object oriented lifecycle and methodology and explain the process of object oriented analysis, especially within the context of iterative and incremental nature of the process,
Apply the iterative and adaptable process frame work of RUP in software development.
Construct well-documented UML-based artefacts from the early phases of the development process for the case study,
Construct the Model of the Problem Space based on the analysis in an industrial CASE tool,
Apply team work skills in a small development team, including: distributing the development workload, resolving disputes, running meetings, and taking minutes,
Identify and create operational (non-functional) requirements of a system including performance and security,
Develop a report based on verbal and written instructions about the performance of software development tasks and associated administrative duties,
Illustrate quality assurance, quality control and user-expectations via reports and theoretical explanation.
Explore possibilities of applying design patterns in software design.
