1 PESIT- Bangalore South Campus Hosur Road (1km Before Electronic city) Bangalore Department of MCA COURSE INFORMATION SHEET OBJECT ORIENTED MODELING AND DESIGN PATTERNS (13MCA51) 1. GENERAL INFORMATION Academic Year: Jul 2015-Nov 2015 Semester(s): V Title Code Duration (hrs) OBJECT ORIENTED MODELING AND DESIGN PATTERNS 13MCA 51 Lectures 52 Hrs 2. COURSE PRE REQUISITE STATEMENT Students should be familiar in basic object oriented language and designing part Objective of learning object oriented modeling and design pattern helps to design any project in a simple and flexible manner and it reduces the coding part. Object oriented modeling and design is a way of thinking about problems using models organized around real-world concepts.

2 The fundamental construct is the object, which combines both data structure and behavior. Object oriented models are useful for understanding problems, communicating with application experts, modeling enterprises, preparing documentation and designing programs and databases. 3. COURSE OBJECTIVES Knowledge in: Introducing students to the concepts and terms used in the objectoriented approach to systems analysis and design Highlighting the importance of object-oriented analysis and design and its limitations. Showing how we apply the process of object-oriented analysis and design to software development. Pointing out the importance and function of each UML model throughout the process of object-oriented analysis and design and explaining the notation of various elements in these models. Providing students with the necessary knowledge and skills in using object-oriented CASE tools 4. COURSE OUTCOMES: After completing this course the student will be able to : Construct models to Show the importance of systems analysis and design in solving complex problems. Will be able to differentiate how the object-oriented approach differs from the traditional approach to systems analysis and design. Explain the importance of modeling and how the Unified Modeling Language (UML) represents an object-oriented system using a number of modeling views. Construct various UML models (including use case diagrams, class diagrams, interaction diagrams, state chart diagrams, activity diagrams, and implementation diagrams) using the appropriate notation. Recognize the difference between various object relationships: inheritance, association, whole-part, and dependency relationships.

3 Show the role and function of each UML model in developing object-oriented software. Apply the Umbrello or Rational Software Suit for the construction of UML models and expressing the appropriate notation associated with each model. Develop an appreciation for and understanding of the risks inherent to large-scale software development, Develop an understanding of the application of OOAD practices from a software project management perspective 5.
