A Level Computer Science: Introduction to databases
This module contains:
Compatible with the following examination boards
Introduction to databases
A database is an organised collection of data, which allows users to obtain and process information according to their requirements. Databases are better storage techniques compared to file systems. The data is only stored once and, hence, data duplication is avoided.
The data is consistent as the changes need to be made only once. These changes are then reflected for all the users using the database.
This A Level Computer Science module introduces databases to your students, explaining:
- The difference between structured data and unstructured data
- The database and its structure
- The relational database and its advantage over a flat-file database
- How entities (or tables) are related to each other in a relational database
