So what is data?Data is words, dates, numbers and images that, when put together, create information.
Some data may make sense to some people but not to others. For instance, can you work out what the following numbers are?

…and what is information?
Information is data that is processed to be useful and meaningful.
Information uses data to provide answers to who, what, where and when questions.

Discuss what data you could gather about children in your class.
Data or information?

Discuss….•What information might your school need about pupils in your school?•Who might want this information? (e.g. parents, government)•What personal data about you and other pupils does your school need to collect to be able to give accurate information?
•Can you think of other types of data (facts or figures) and information that interest you?
Data or information?

?Can you work out which of the following are data and which information?
•Your friend’s address•Your friend’s phone number•What’s on TV tonight•Where to go for a fun day out this weekend•Your school’s holiday dates•The different types of dinosaurs we have evidence about•The number of dinosaur bones owned by the Natural History Museum

Data can be numbers, words, measurements, observations or descriptions. For instance a museum needs to record data about objects.

Until it is processed and turned into something useful.
Data creates information.

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.
![Page 11: Tag London Crowdsourcing project KS2 Lesson 1. Lesson objectives To find out: What is data? What is information? What is a database and how are they used?](https://reader036.vdocument.in/reader036/viewer/2022062421/56649d765503460f94a57613/html5/thumbnails/11.jpg)
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

• advantages of paper-based databases• disadvantages of paper-based databases
![Page 14: Tag London Crowdsourcing project KS2 Lesson 1. Lesson objectives To find out: What is data? What is information? What is a database and how are they used?](https://reader036.vdocument.in/reader036/viewer/2022062421/56649d765503460f94a57613/html5/thumbnails/14.jpg)
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
![Page 15: Tag London Crowdsourcing project KS2 Lesson 1. Lesson objectives To find out: What is data? What is information? What is a database and how are they used?](https://reader036.vdocument.in/reader036/viewer/2022062421/56649d765503460f94a57613/html5/thumbnails/15.jpg)
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
![Page 16: Tag London Crowdsourcing project KS2 Lesson 1. Lesson objectives To find out: What is data? What is information? What is a database and how are they used?](https://reader036.vdocument.in/reader036/viewer/2022062421/56649d765503460f94a57613/html5/thumbnails/16.jpg)
But when we use the term 'database' we generally think of a computer-based database.
![Page 17: Tag London Crowdsourcing project KS2 Lesson 1. Lesson objectives To find out: What is data? What is information? What is a database and how are they used?](https://reader036.vdocument.in/reader036/viewer/2022062421/56649d765503460f94a57613/html5/thumbnails/17.jpg)

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
![Page 19: Tag London Crowdsourcing project KS2 Lesson 1. Lesson objectives To find out: What is data? What is information? What is a database and how are they used?](https://reader036.vdocument.in/reader036/viewer/2022062421/56649d765503460f94a57613/html5/thumbnails/19.jpg)
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

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?
![Page 21: Tag London Crowdsourcing project KS2 Lesson 1. Lesson objectives To find out: What is data? What is information? What is a database and how are they used?](https://reader036.vdocument.in/reader036/viewer/2022062421/56649d765503460f94a57613/html5/thumbnails/21.jpg)
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!
