Relational Databases
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 relational database is efficient over flat-file databases as it is more efficient and takes up less space in memory. Data redundancy, which is repetition of data in a database, is overcome in relational databases. Hence, a large set of data is distributed over various tables and connected using a relationship in the relational database. For example, a library may store information such as a book list, member list, department, book location, research paper list, staff details and many more. Storing these details in a single flat-file system would lead to more memory space requirement and data redundancy.
This GCSE Computer Science module introduces relational databases to your students, explaining:
- Characteristics of relational database
- What is normalisation
- Relationship between entities
- How to work with the database
