What is DBMS?
Wikepedia definition of DBMS:
(1) Is a set of programs that enables you to
store, modify, and extract information from
a database, it also provides users with tools
to add, delete, access, modify, and analyze
data stored in one location;
(2) Active research area;
(3) A multibillion dollar business.
Old DBMS

Old DBMS:





Stand-alone,
Static, non-interactive,
Very limited representing interaction
between objects,
Confusing set of data models,
Independent application
Current DBMS
Parallel
 Distributed
 Information visualization + HCI support
 Capable of learning and supporting decisionmaking process
 Enabling
 Supports transition: data->information
->knowledge->wisdom

Motivation


Organizations are relying less on their own
data automation and more on sharing.
Portability of the data is a key component to
finding and evaluating data and facilitating
data transfer.
New data models / structures emerge to
better represent different phenomena.
Extremely large data set problem becoming a
crucial one.
Security and privacy play pivotal role.

organizations and outside organizations (i.e. public access)
