Description

This module provides an overview to data management aspects of Data Science. It provides students with an introduction to Databases. Students should learn how to design and create a database using the entity-relationship model, express queries in SQL, understand relational database theory and validation concepts such as normalisation and functional dependencies.

Learning Outcomes

1. To understand the relational model theory that underpins database design.
2. To translate an informal problem specification into a well-formed Entity-Relationship model and map this to an appropriate relational schema.
3. To demonstrate a proficiency in writing SQL expressions to query and alter the database.
4. To understand the advantages of applying normalisation theory to validate database schemas.
5. To be able to apply summarisation and cleaning techniques in database applications for data science.
