1. Differentiate between database types and capacities. (300 words)
Solution
They are six important types of databases 1.Operational 2.End-user 3.Centralized 4. Distributed
5. Personal and 6. Commercial database.Till recently, the data types could be grouped as
numeric, character, date, memo and logical .As multi-media capabilities are becoming comÂmon
to computers of different sizes, the databases are also going multi-media. Modern DBMS permits
storage and retrieval of data types such as business graphs, spreadsheets, art clippings pictures,
sound, video, etc. These new data types are termed as ‘objects’.
Operational Database store data relating to the operations of the enterprise.
End-User databases are shared by users and contain information meant for use by the end-users
like managers at different levels.
Centralised databases store the entire informaÂtion and application programs at a central
computing facility
Distributed databases have contributions from the common databases as well as the data captured
from the local operations
Personal databases are maintained, genÂerally, on Personal computers.
The database to which access is provided to users as a commercial venture is called a
commercial or external database.
Database capabilities:
Persistent Storage for Program Objects and Data Structures.
Providing Multiple User Interfaces.
Representing Complex Relationships among Data.
Enforcing Integrity Constraints

2. Providing backup and memory
every database type must possess these capabilities so that it would be a friendly interface and
doesnt annoy the end user
