Types of Database
Databases can be constructed in various ways according to the user’s requirements.
Flat file Database
- This is a single table such as can be set up in a spreadsheet
- Only suitable for very simple data-handling requirements, such as an address book
- As soon as requirements become more complicated, they lead to all sorts of problems
In some situations, items in a database relate to each other like the branches on a tree. Then a hierachical database may be suitable.
