3. that can identify and resolve constraint violations in existing datasets.
4. that take transaction processing and concurrency control issues into account when selecting a database management system for a given set of requirements.

Networking & Virtualisation
This module is included because of the heavy reliance which modern computing has on networks. Most systems either need to connect to the network for data transfer or management or rely on the network to support multi-processing, parallel computing. The shift to the Cloud in recent years has increased the need for skilled workers who understand underlying protocols, services and network topologies. This module will lead learners through the fundamentals of networking from basic LANs to Enterprise scale networks and the services that they support. It will also prepare Learners for the concepts that enable Cloud Computing and Virtualization. The hands-on approach will mean that they must build, maintain, and troubleshoot their own networks initially in a physical form and eventually in a virtual format.

Operating Systems and Architecture
The aim of this module is to:
1. develop professional system administrators, capable of maintaining modern business IT architectures.
2. enable graduates to secure IT infrastructures against modern and future security risks.
3. promote professional expertise that is OS independent, allowing graduates to design system architectures independent of personal preferences.
4. encourage adherence to professional best practices in the development of custom system architectures.
5. develop learner self-reliance and initiative in the provision of professional system configuration consultancy.

Strategic Business IT
It is the aim of this module to provide the learner with knowledge of:
1. The macro and micro business environment and the concepts, tools and techniques that facilitate its analysis.
2. The relationship between business and information technology and how information technology can establish and maintain a competitive advantage.
3. Differences between proprietary and open source software models and how they can support and affect IT business related solutions.
4. Emerging technologies and how business reacts in relation to future strategic planning

Semester 2
