This module extends the principles of SQL database modelling laid down in the first year. It introduces the concept of NoSQL databases and compares the strengths and weaknesses of all three approaches (SQL, IR and NoSQL paradigms)
The aims of this module are to extend the principles of SQL database modelling and normalisation laid down in the first year, to describe the field of Information Retrieval, to introduce the concept of NoSQL databases and hence to compare the strengths and weaknesses of different approaches.
After completing this module, students will be expected to be able to:
1. Understand SQL database modelling and normalisation;
2. Appreciate the principles of Information Retrieval;
3. Apply and evaluate IR in a practical context;
4. Discuss differences between models such as SQL, IR and NoSQL.
