• Basically databases are used to store information.
• A primitive form of ‘database’ is a filing cabinet.
• The fundamental types of databases include,
Relational: Data is kept in fixed tables with defined relationships
Object Oriented: Dissimilar data can be stored in a single list (relational databases are a sort of subset of these databases)
• Databases allow information stored on one computer to be shared with other computers.
• Data stored in relational databases is commonly access using SQL (Structured Query Language)
• Databases handle problems of,
data locking (only allow one user to modify at once)
data sharing (other users can view)
