KS2 ICT Quiz
Databases
A database could be made of all the planets showing their size, their distance from the Sun and much, much more!

Databases

In KS2 ICT children will take a look at databases. These are systems for the storage of data or information and are one of the most common uses for computers.

Databases are storage systems which allow you to store and organise vast quantities of information or data. They can be very useful tools in all sorts of different situations. A historian might use one to list all of the monarchs of England for example, and input the length of their reign, their date of birth, how many children they had or any other piece of statistical information he wanted to add. He could then order the list in several different ways, for example alphabetically, by age or by year of birth. Databases are organised in a way that makes them easy to search for the information they hold.

See how much you know about data storage systems in this ICT quiz.

  1. Which of the following types of information could you store in a database?
    Data could be any kind of information you want to keep a record of
  2. In a database about planets, all of the information about Mars would be held on what?

    A field contains only one piece of information. A record on a planet database might have several fields: size, distance from the sun, time taken to orbit, number of moons, etc
  4. What is a database search called?

  5. Imagine an animal database in which each record has these fields: number of legs, habitat, lifespan, diet. Which of the following pieces of information could NOT be found out from the database?
    The database would need an additional field for class (i.e. reptile, mammal, bird, amphibian, fish, etc.) before it could tell you the answer
  6. Which database might you use to help you find your next library book?
    A catalogue is a complete list of items, for example all of the books owned by a library
  7. Which fields would you expect to find in a database of library books?
    Besides including information on author, title, genre and number of pages, one of the most important pieces of information is location - this helps you find the book you choose! The database would also be able to tell you if the book was currently available or out on loan
  8. If you had a database for the children in your class and you wanted to organise the list of children by date of birth, you would instruct the database to do what?
    A database can be sorted alphabetically or numerically by ascending or descending order
  9. A planet database could be organised in which of the following ways?
    A list of planets could be sorted alphabetically OR by distance from the sun, but not both at the same time (this applies to the time taken to orbit, as well)

    A database holds ... data!
