Year 4 - What are databases?
Michael Sheerin
Do you play Top Trumps? Well if you do you are using a card database. We are learning to use databases to find the answer to questions. Database are very useful for storing, organising and sorting information. We looked at Top Trump packs to understand the structure of a card database, each card is a record and each record has a set of fields. Information can be either a picture, a number or text. We are going to compare a card databases with database on the computer.
Can you find out where databases are used in real life?
