The Database Concept

Databases revision

Databases

A good overview of database theory, which is sufficient to cover the syllabus for most GCSE courses, and is a good introduction to the topic for A Level and IB courses. The differences between structured and unstructured data are covered, along with database basics (fields, records, tables). The second half of the video explains relationships in more detail, including 1-to-1 and 1-to-many relationships.
