As distributed software systems have grown in size, the granularity of the problem domain has also grown. This change has brought about the realisation that the greatest complexity in most systems manifest itself as a problem of how software can interact over heterogeneous and distributed environments. The trend in IT is also moving towards building such systems for the enterprise.

Software engineers will often employ middleware to contain heterogeneity and distribution complexity for the enterprise. Frameworks, therefore, have to be designed with a clear understanding of the middleware they utilize. Existing middleware can be classified into three types, transactional, message-oriented and object-oriented. The object-oriented approach provides much promise as it address much of the complexity issues through encapsulation and modularity.

It is therefore necessary to provide a unit to address these issues and at the same time, provide practical experience in the development of such appplications with the focus on applications for the enterprise.

As distributed systems become more complex, moving towards the enterprise architectural framework, it is important to focus on developing large applications for the enterprise.

This unit is one of the core units for Master of Information Technology specialisation, Enterprise Architecture.

There are two other existing units that deal explicitly with enterprise systems: CPE4004 and IMS5052. The former focuses on the object-oriented analysis and design of distributed enterprise systems, while the latter addresses the issues, problems and strategies of concern in the implementation of enterprise systems using a theoretical and case-based approach. This unit specifically deals with the object-oriented development of enterprise systems and provides hands-on experience using existing tools for the actual deployment.

As one of the core units for Enterprise Architecture specialisation, this unit will provide the development skills necessary to build enterprise applications.

Upon completion of this unit, students should be able to:

1. identify key components of the object-oriented enterprise architecture.
2. understand the various advanced Java technologies used to build applications for the enterprise.
3. use the advanced Java libraries to implement a medium-sized enterprise application.
4. display an in-depth understanding of a selected topic related to enterprise application development.

Additionally, either via a literature survey or a case study, students should demonstrate the capacity to identify and critically evaluate current trends in distributed software development that might contribute to their implementation.

Upon the completion of this unit, students will have the knowledge of a commercially relevant programming language and its associated libraries, and gain the understanding of:

• the object oriented programming paradigm and how to apply it to distributed programming.
• the technical issues underlying distributed enterprise application development, including concurrency and transactions, interoperability, scalability and manageability.
• the role of a Enterprise Architect in developing these systems, including managing system workload and capacity, understanding the required business processes, and managing the development and testing of enterprise systems.

Upon the completion of this unit, the students will:

• appreciate the need to develop distributed software for the enterprise on the World Wide Web.
• recognise the issues involved in enterprise application development as very different from non-distributed standalone software development.

Upon the completion of this unit, students will have skills in designing, developing, deploying and testing a small to medium sized web-based distributed application written in Java for the enterprise

As application development advances towards web-based distributed applications for the enterprise, this unit introduces techniques and addresses various theoretical issues pertaining to the development of such applications. The Java programming language and Java technologies will be used in the practical assignments to implement the theoretical concepts. Advanced Java topics to be covered and discussed include Enterprise JavaBeans, Java ServerPages, Java Servlet Technology and Java Database Connectivity. Students will be able to address other issues related to the development of large scale enterprise systems including: transactions and distributed transaction processing, interoperability and persistence, scalability and the choices facing enterprise system architects and developers.
