1. Database Design and Development
Database Basics

2. Learning Intention
I will learn about the structure of a database.

3. Storing data A database is a structured way to store data.
An entity is a single person, place or thing about which data can be stored. E.g. a car, a flight or a country.

4. Storing data An entity has attributes.
e.g. a car entity with 3 attributes:
make: Honda
model: Civic
registration: SN07 GHJ
The attributes have values that can be edited.

5. Storing data
When data is entered into a database, attributes become the fields of a record.
A record holds all the information about a single entity.
A collection of records is a table.

6. Record
Table
Fields

8. Attribute Types Text – e.g. Jane, G71 7RI, 07923 123 456
[phone number starts with zero, may contain spaces, not used in calculations]
Number – e.g. 98, 0.23
Date – e.g. 25/12/2017 (formatted dd:mm:yy)
Time – e.g 15:05 (formatted hh:mm)
Boolean – true/false

9. Practical Tasks 1 & 2
You are now going to use MS Access to create a Database to hold details of two types of entity.

10. Success Criteria
I can describe the structure of a database and I can create tables in a database.
