Data refers to different types of information. Two areas where the concept of data can be explored is through the use of spreadsheets and databases
A spreadsheet is an application which can be used to sort, list and represent information.

There are a number of different programs which can be used to create spreadsheets including: Microsoft Excel; Numbers; Corell Quattro Pro; Google Docs and Lotus 1-2-3.
There are a number of ways in which spreadsheets can be used in the classroom.
Ideas include entering simple data into a spreadsheet to create mathematics learning activities, creating timelines and designing graphs and probability charts. Other activities which can involve the use of spreadhseets include getting students to use a spreadsheet to solve a story problem; investigate fast food restaurants and plan a healthy meal.Ideas include entering simple data into a spreadsheet to create mathematics learning activities, creating timelines and designing graphs and probability charts.

A database is a location where information is stored and retrieved and are generally composed of two or more tables.
The data is organised in a way in which all of the data in the different tables are linked to one another by a primary key. A primary key is a field in each of the tables that is common to all of them. The primary key is used to look up or trace data in each of the tables. Databases have two main uses:
Storing information and Sorting Information.
There are all sorts of information which can be stored in databases. An example of some of the things which could be stored include: personal information; telephone numbers; business clients; names and addresses of people and parents contact information for children in school.
Below is an Example of a link to some children’s databases:
