Creating a databaseDetective Turner and his team of detectives have been busy interviewing people. The team has now interviewed everyone using your questionnaire. This information is taking a long time to sort through, and they are having difficulties finding the information they need.
By the end of this tutorial you will be able to:

Database theory
• A database is a computerised system for storing large amounts of information in electronic format.• It allows the user to find specific records, and sort and filter the data stored within it to provide useful reports.
What is a database used for?
A database is built from tables of data, each table contains records, and each record contains fields.
A record is a complete set of information about a person or thing. For example: one person’s name, date of birth, address.
A field is one piece of information such as Surname.
How does a database store information?
