Software System Components

Level 2/I

Robert Hendley Shan He Semester 1 20 credits
Co-ordinator: Robert Hendley
Reviewer: Rami Bahsoon

The Module Description is a strict subset of this Syllabus Page.


This module presents more advanced software development techniques, enabling the design and development of programs of medium-scale size and complexity. Through a series of lab exercises, students apply concepts taught in the lectures and at the same time practice the design and development of medium-scale programs. Together with its companion module, Software System Components B, it is designed to equip students with programming abilities which may be needed in an individual final year project. The module covers the three topics of databases, web programming and concurrency, and distributed computing.


The aims of this module are to:

  • improve students' programming skills generally, and develop students' programming design and development skills to cope with large programs
  • provide programming experience with more advanced but commonly used Java class libraries and other packages as appropriate
  • teach specific skills in databases, web programming and concurrency, and distributed computing

Learning Outcomes

On successful completion of this module, the student should be able to:

1 use Entity-Relationship diagrams to construct and explain conceptual models of databases, and then design tables for a relational database 2 write and explain SQL queries for a relational database 3 query and update a relational database from Java
4 explain the servlet model and structure, including the servlet lifecycle and application/session/request/page scope
5 configure, install and use servlet based web applications, implementing correct servlet request and response code, including html form processing, session handling, database connectivity and security
6 explain and evaluate web application architecture and technologies 7 explain the concepts and issues of threads and synchronisation, including thread pools
8 implement, debug and test multithreaded programs with appropriate synchronisation, in a variety of contexts such as Swing, collection classes and network I/O mechanisms 9 explain and implement socket based communication
