On successful completion of this module students should be able to:
1. Demonstrate specialised skills to achieve the reuse of design expertise through the application of software design patterns and particularly in the context of designing and building distributed applications.
2. Critically describe the generic architecture of multi-tier, distributed applications.
3. Assess critically the appropriateness of various Internet-based communication technologies to solving the communication requirements of a variety of distrbuted applications.
4. Build, and then critcally appraise, a simple, multi-tier distrbuted application that employs the use of appropriate design patterns and communication technologies, and exhibits simple Rich Internet Applicatioin characteristics.
5. Demonstrate a critical appreciation of design issues encountered when developing multi-tier, distributed applications.
6. Demonstrate a critical appreciation of the security requirements of distributed applications.
7. Demonstrate the undertaking of original research within the area of building distributed applications.
Teach best practice in building web applications with rich and responsive user interfaces; enterprise design patterns; support for business-to-business application interoperation; and security. Give students the opportunity to build a distributed application that employs best practice in these areas and in agile methodologies and accessibility requirments, taught in other modules. Make students aware of the opportunities and limitations of various distribution technologies. Allow students to demonstrate their ability to apply such technologies.
Students will be made aware of the opportunities and limitation of various distribution technologies, and also demonstrate their ability to apply such technologies.
General introduction to the module. Distributed application architectures: client and server (two-tier, three-tier, n-tier), peer-to-peer. Distributed object systems: opportunities and limitations.
2. Building a simple web application using a web application framework such as Ruby-on-Rails. The web application freamework and its support for the MVC enerprise design pattern and for object-relational mapping.
Introduction of a running example used during some of the module.
Testing the application. Any new language, such as Ruby, will be introduced.
3. Internet-based communication technologies and architectures.
Support for interoperability by various technologies: e.g. sockets, Java Remote Method Invocation (RMI), XML-RPC and Soap-based web services. Representational State Transfer (REST) web services. Design issues. Resource Oriented Architecture (ROA). Application of XML-based web services to the running example. Interoperability with Web 2.0 social networking sites.
4. An introduction to building Rich Internet Applications.
5. Security of distributed applications.
Including cryptography, symmetric and asymmetric algorithms, Java Security Model example, Transport Layer Security protocol, Pluggable Authentication Module architecture, mitigating web hacking attacks (cross-site scripting, SQL injections and others), single sign-on.
