Each question helps you build key knowledge and skills.

  • 1A database stores data in an organised way so it can be searched and updated easily.
  • 2A table is made up of records, which are rows of related data, and fields, which are the columns holding one type of data each.
  • 3A primary key is a special field that gives every record a unique value so no two rows are the same.
  • 4Databases can be flat file, using just one table, or relational, using several linked tables to avoid repeating data.
