This module addresses some of the key concepts required for the traditionally important area of data management and the increasingly important area of data analytics. You’ll gain a practical, legal and ethical understanding of how to access, query and manage data collections using traditional relational databases and contemporary NoSQL approaches. Using real-world datasets, standard software packages and data visualisation techniques, you’ll learn how to organise and analyse data collections to answer questions about the world and develop an appreciation of user needs surrounding data systems.
This module will provide a broad overview of modern data management and analysis concepts, techniques and tools. It will compare traditional relational databases with an alternative model (a NoSQL database). It will help you learn how to choose the most appropriate means of storing and managing data, depending on the size and structure of a particular dataset and its intended use. You will be introduced to preliminary techniques in data analysis, starting from the position that data is used to answer a question. You will be introduced to a range of data visualisation and analysis techniques that will instil an understanding of how to start exploring a new dataset.
To ensure that you are comfortable handling datasets, you will explore a range of real-world datasets to illustrate the key concepts in the module. Sources such as data.gov.uk, the World Bank, and other national and international agencies may be used to provide appropriate data. You will spend approximately equal time between issues in data management (technical and socio-legal issues in storing and maintaining datasets) and data analytics (understanding how data can be used to answer questions).
The module is framed around a narrative that looks at managing and extracting value and insight from a range of increasingly large data collections. At each stage, a comparison will be drawn between different ways of representing the data (for example, using various charts or geographical mapping techniques) and the limitations of the presented mechanisms. To enable you to get a feel for the use of data, each stage will also include an overview of some data analysis techniques, including summary reporting and exploratory data visualisation. Richard Hamming’s famous quote drives this module: ‘The purpose of computing is insight, not numbers’.
Some of the key ideas are:
Introducing data analysis
This unit will start with a data file, such as a spreadsheet, and provide you with a brief introduction to some basic operations on simple data files. This will give you an opportunity to study an outline of the module's key ideas and help you become familiar with the module software.
Concepts in data management
You will examine three key areas in data management: data architectures and data access (CRUD), data integrity, and transaction management (ACID). Each topic will be illustrated using a relational database and one non-relational alternative. The advantages and limitations of each model will be discussed.
Legal and ethical issues
Here, you will consider the legal and ethical issues involved in managing data collections. You will be required to obtain and read (parts of) the Data Protection Act and the Freedom of Information Act and demonstrate how these apply to data management issues. You will also consider privacy, ownership, intellectual property, and licensing issues in data collection, management, retrieval, and reuse.
Concepts in data analytics
These sections will focus on using data to answer a real question; the focus will be on exploratory techniques (such as visualisation) and formulating a question into a form that can be answered realistically using available data. Issues in processing techniques for large and real-time streamed data collections will also be addressed, along with strategies and technologies (such as MapReduce) for handling them. In this part of the module, you will use a statistical package such as the Python scientific libraries and/or ggplot2 to visualise the data and carry out appropriate analyses.

Data management and analysis (TM351) starts once a year – in October.
It will next start in October 2026.
We expect it to start for the last time in October 2027.
