| Module Description: |
Databases are used to store, manipulate and retrieve data in nearly every type of organisation, including business, health care, education, libraries and even our mobile phones. In this module students will learn the fundamentals of database systems, the relational model and Structured Query Language (SQL). |
| Learning Outcomes |
| On successful completion of this module the learner will be able to: |
| LO1 |
Outline the purpose of databases and the various types of database models used to store data. |
| LO2 |
Discuss database management systems (DBMS) and outline its objectives. |
| LO3 |
Design a relational database composed of tables and define keys and relationship among tables. |
| LO4 |
Create, populate and manipulate a simple relational database and its tables. |
| LO5 |
Define SQL queries to select, insert, update, query and delete data from a database. |
| LO6 |
Use tools to create and manage databases. |

Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
