9. Data can be numbers, words, measurements, observations or descriptions. For instance a museum needs to record data about objects. Profile of a Roman marble head of Mithras Date: 180 AD - 220 AD Maker/Artist: Unknown Meaningless: It does not have meaning Until it is processed and turned into something useful. Data creates information.

10. A database is like a library – it stores pieces of information called a ‘record’. So what is a database? Describe what you see in these pictures.

11. Make a list of: paper-based databases computer-based databases databases you use. Then discuss: what type of data would you search for? how would you find it? Discuss in pairs

12. Feedback List some databases Make sure you list some computer-based and some paper-based databases. Computer-based databasesPaper-based databases You might like to glance at a popular website online together!

13. Discuss in pairs advantages of paper-based databases disadvantages of paper-based databases

14. Some advantages of paper-based databases Inexpensive to set up You don’t need electricity, so it will work if you have a power-cut Don’t need a computer – which is expensive

15. Some disadvantages of paper-based databases  Can be lost  Not as easy to make back-up copies  Hard to update or make changes  Card systems can get in a muddle if cards not replaced in the correct order  Can take a while to search for a particular record

16. But when we use the term 'database' we generally think of a computer-based database.

17. Discuss in pairs advantages of computer-based databases disadvantages of computer-based databases

18. Some advantages of computer-based databases Can easily make back-up copies Can easily make changes Can easily sort data into order e.g. alphabetical Can search very quickly Can import or export data to/from other digital sources

19. Some disadvantages of computer-based databases You need to have a computer If there is a power-cut, you can’t use it You often need training to learn how to use them Can be expensive to set up (often needs an expert to make it) Can be lost or damaged

20. Now discuss how we find information from a database? How do you find the right information in a database? In a library what data is kept about all the different books? How do you search for information on computer-based databases?

21. Database search We can search a database to find the information we are looking for. If the database has a search function that helps sort the information we want to find!

22. Recap: Key words CAN YOU UNSCRAMBLE THESE WORDS? (Click forward for answers) ADAT MIOFNRATNIO SEBATADA PC-SMUTOBAERED DATA INFORMATION DATABASE COMPUTER-BASED

23. Keywords Data Information Processed Database Computer-based database Paper-based database Search function ? Do you know the meaning of these words ?
