DESIGN PATTERNS Subject Code: A70530 Regulations: R15 – JNTUH Class: IV Year B.Tech CSE I Semester Department of Computer Science and Engineering BHARAT INSTITUTE OF ENGINEERING AND TECHNOLOGY Ibrahimpatnam - 501 510, Hyderabad DESIGN PATTERNS (A70530) COURSE PLANNER I.COURSE OVERVIEW: The course covers a wide range of software development concepts, abilities, and skills, from analyzing a problem to implementing a solution, also discuss the design patterns in Smalltalk MVC architecture, Express representation invariants, understand their impact on efficiency an66 d ease of implementation, and implement them as runtime assertions. Outlines the differences between structural patterns and behavioral patterns of a model. The course explains about common design vocabulary. This course helps to determine how to be recognizing a design and they can reduce the amount of refactoring, helps to use primitive techniques such as objects, inheritance, and polymorphism. Describes problems that occur in a design how to resolve them and how to evaluate them. II.PRE-REQUISITES: Object Oriented Analysis and Design. Data structures and algorithms. Programming Language (C++ or Java) III.COURSE OBJECTIVE: 1 Demonstration of patterns related to object oriented design. 2 Describe the design patterns that are common in software applications. 3 Analyze a software development problem and express it. 4 Design a module structure to solve a problem, and evaluate alternatives. 5 Implement a module so that it executes efficiently and correctly. IV.COURSE OUTCOMES: S.NO Description Bloom’s Taxonomy Level 1 Construct a design consisting of a collection of modules. Create 2 Exploit well-known design patterns (such as Iterator, Observer, Analyze Factory and Visitor). 3 Distinguish between different categories of design patterns. Analyze 4 Ability to understand and apply common design patterns to Understand incremental/iterative development. 5 Ability to identify appropriate patterns for design of given Remember problem. 6 Design the software using Pattern Oriented Architectures. Create V.HOW PROGRAM OUTCOMES ARE ASSESSED: Program Outcomes Level Proficiency assessed by PO1: Engineering knowledge: Apply the knowledge of 3 Assignment, Exercises mathematics, science, engineering fundamentals, and an engineering specialization to the solution of complex engineering problems.
