A relational database is a type of database that is structured and allows users to identify and access data which is in relation to other data. A large set of data is distributed over various tables and connected using a relationship in a relational database. Hence, no redundant data.
A relational database is efficient over flat-file databases as it is more efficient and takes up less space in memory.
This KS3 Computer Science module introduces relational databases to your students, explaining:
- The relational database and its advantage over a flat file database
- How entities (or tables) are related to each other in a relational database
