Level 4

Module	Credits	Compulsory/optional
Introduction to Programming and Discrete Structures	30 Credits	Compulsory
This module will teach you core knowledge and skills in programming and some of the key mathematical and logical concepts that underpin computer science. There are two strands: The programming strand focuses on teaching you how to write programs in the Python 3 language, paying particular attention to fundamental programming concepts: algorithmic and functional decomposition, understanding and using assignments, conditionals, loops and functions, and applying techniques for testing and debugging. We will provide a series of examples and exercises to help you develop your understanding of program code and the programming process. The discrete structures strand focuses on developing your understanding of mathematical and logical structures that are of relevance to programmers. We will introduce you to a coherent set of concepts from discrete mathematics and logic, including sets, relations, functions, propositions, and predicates, and illustrate how they may be applied in the modelling and solving of computational problems.
From Silicon To C	30 Credits	Compulsory
This module focuses on the principles and practicalities of the multilevel organisation of computer systems. Students will have opportunities to investigate and build computational structures in hardware and to program with machine instructions and C programming language and see how they support one another. The abstractions available at higher levels (programming languages) will be de-mystified by progressively bringing them down to lower levels all the way to the silicon structures that serve as the foundation of any computer system. This will help students to learn high-level programming (when they do) in an informed and efficient way by creating cost intuitions that cannot be developed while keeping solely to abstract constructs such programming normally deals with. Students will be offered a significant number of development exercises ranging from very basic to challenging and will be helped. Independent learning by practising is key to this.
Data Modelling for Databases	15 Credits	Compulsory
This module introduces the concept of the relational model of database systems introduced by Codd [1]. It will focus on the principles of data modelling, from conceptual modelling through to physical. It will introduce techniques and tools to possibly include but not be limited to Requirements Gathering, Whiteboarding, Entity-Relationship Modelling, Normalisation, Relational Algebra, physical design, and querying via SQL. The module also introduces some of the basic operational requirements of a modern enterprise RDBMS with topics supporting the students' understanding of the physical design of the database; hence, subjects such as Query Optimisation and Transaction Processing will be introduced. The module will be highly practical, focusing on hands-on use and implementation of the tools and techniques introduced. An enterprise database system will be used via a specialist client interface throughout, and multiple case studies will be provided as support for learning. [1] Codd, Edgar Frank (June 1970). A Relational Model of Data for Large Shared Data Banks Communications of the ACM. 13 (6): pps 377-387.
Computational Problem Solving	30 Credits	Compulsory
This module builds on concepts and practices taught in Introduction to Programming and Discrete Structures, continuing both strands but bringing them closer together. It uses discrete mathematics and logic as sources of example problems and tools for describing and reasoning about programs. In the programming strand, the emphasis is on designing and implementing solutions to well-specified problems. Students will be given guidance on problem representation and choice of data structure and expected to choose/write appropriate algorithms for themselves and to implement them in Python. In the discrete structures strand, the emphasis is on understanding how mathematical and logical structures and reasoning may be used in the service of programmatic problem-solving. This strand will also serve as a source of example problems for students to solve.
Team Software Project	15 Credits	Compulsory
Students will work on a project within a team. Project specifications are provided, ensuring students have an opportunity to develop project and time management, professional, team communication and reporting, risk, presentation, and self-evaluation skills. The projects are based on typical commercial/industrial scenarios and incorporate the concepts of specification, design, implementation, and testing, designed to develop a range of employability skills. Project specifications will, where possible, promote contemporary ethics, social and professional issues in computing.

Level 5

Module	Credits	Compulsory/optional
Algorithms and Data Structures	15 Credits	Compulsory

Several sensors will be studied to demonstrate the data-gathering facilities available. One inexpensive and well-supported loT platform will be chosen by the module leader as a running example for content delivery. This can be ESP32 or Arduino or any similar evaluation module available at a small cost (the price of a good textbook) and which can be interfaced with a PC via a USB port. All teaching will be accompanied by exercises on the chosen platform.
Database Systems	15 Credits	Compulsory
This module assumes an understanding of fundamental relational database design, implementation, and use. It will introduce other database paradigms including, but not limited to Business Intelligence and Data Warehousing, 'Schema-free'/NoSQL databases, and Graph Databases. Teaching will be directed at both the practical design, implementation, and use of these systems as well as understanding the key advantages of each, providing an ability to compare and critique their appropriateness in a range of scenarios. In using these systems, the module will consider the limitations and appropriateness of query languages and the interaction between query languages and programming languages.
Principles and Practices of Large-Scale Programming	30 Credits	Compulsory
This module provides the knowledge and skills needed for developing a large-scale software system using object-oriented tools and techniques and an appreciation of the professional issues involved in such development, including working in teams. As well as correctness, good program design, which provides maintainability and re-use, will be expected in assessments. Object-oriented design guidelines will be used in early examples and exercises and then made explicit at a later stage. Principles to foster good design will include modularisation, abstraction, reduced code duplication, high cohesion, and low coupling, as well as object-oriented guidelines such as the Law of Demeter, programming to an interface, not an implementation, MVC, re-factoring, and a selection of design patterns.
