1. Flat File Database 2. Relational Database
☞ Data is stored in a single table.
☞ Usually suitable for less amount of data.
☞ Data is stored in multiple tables and the tables are linked using a common field.
☞ Relational is suitable for medium to large amount of data.
☞ Database servers are dedicated computers that hold the actual databases and run only the DBMS and related software.
☞ Databases available on the database servers are accessed through command line or graphic user interface tools referred to as Frontends
☞ Database servers are referred to as Back-ends.
