What is a Database? A structured collection of records or information stored on a computer and organized in one of the following methods:
- relational model - relationships between information are based on a common item or sets of commonalities
- hierarchical model - data is organized in a tree-like structure of parent/child relationships. Each parent can have multiple children but each child can only have one parent.
Who needs a Database?
Databases are the preferred method of storage and organization for large volumes of information where coordination and access is required between many users. Individual users benefit from the convenience of databases through applications such as e-mail programs and personal organizers. |
