The conceptual view- this I concerned with how the data is organised. It has to do with the design of the tables and how they are linked
The physical view- this is concerned with how the data is actually stored on the storage medium.the designers and the users of this database are not concerned with this detail
A database is a store of data that is: persistent- it is stored on a permanent form such as a hard disk or flash memory.Related- the data in the database is related to something and is not random information. Organised- the data inside the database is stored in a structured and helpful way.
