Introduction

SE VLabs Research analysis manifest clear trends of growing interest of the Computer Science students towards e-learning. To keep this trend as well as the pace with the rapid advancement of software technologies the "Software Engineering Virtual Lab" has been developed. This lab attempts to provide basic concepts to the students on a wide range of topics including Requirements analysis, ER modeling, identification of domain classes, use-case diagrams, designing a test suite. Ample illustrations and simulations are used to reinforce one's understanding. Once concepts are clear, a set of exercises given on the concerned topics would help the students to evaluate themselves and their progress of learning. The main focus is to enable the students to interact with the "virtual" teacher in an effective and efficient manner compared to how they would do in a real lab on the subject.

Target Audience

This lab is suitable for undergraduate or postgraduate students having a course on Software Engineering. An overview of Object-Oriented Programming would be helpful, although not manadatory. A little familiarity with JavaScript is required to work on the experiment on "Designing test suite".

Relevant Courses

Rajasthan Technical University The set of experiments specified here has an almost complete match with the list of experiments prescribed for the "Software Engineering Lab" as part of the B. Tech. (Computer Engineering) course offered by Rajasthan Technical University. Other Universities Further, around 90% of the originally prescribed experiments would help to reinforce the learning on different courses offered by many other Indian universities, some of which are listed below.

PG Courses

  • "Software Engineering" course offered for M.Tech. (IT) at Visvesvaraya Technical University
  • "Object Oriented Software Engineering" course offered for M.Tech. (IT) at Andhra University

UG Courses

  • "Software Engineering" course offered for B.Tech. (IT) at West Bengal University of Technology
  • "Software Engineering" course offered for B.Sc. (CS) at Delhi University

Objectives

The Software Engineering Virtual Lab has been developed by keeping in mind the following objectives:

  • To impart state-of-the-art knowledge on Software Engineering and UML in an interactive manner through the Web
  • Present case studies to demonstrate practical applications of different concepts
  • Provide a scope to students where they can solve small, real life problems

All the while it is intended to present Software Engineering as an interesting subject to the students where learning and fun can go alongside.
