Ans. DataBase Management System
A Database
management system is a computerized record-keeping system. It is a repository
or a container for collection of computerized data files. The overall purpose
of DBMS is to allow he users to define, store, retrieve and update the
information contained in the database on demand. Information can be anything
that is of significance to an individual or organization.
All
the possible applications of a Database Management System in any IGNOU'S
Regional Center :-
(i) Database is used to store students
details in a place
We know Database is used for storing Data and
Information.In IGNOU'S Regional Center all data and Information
related to student , staff and employees are stored from where we can
access data and Information , update and also Delete the Data and
Information.
(ii) Easy
Query processing and management
From DBMS we can easily generate Query and we
can easily manage it. And we can easily our database.
(iii) Easy
to understand and user friendly
The language we use in DBMS is easily
understandable. Query Statements like SELECT, DELETE & UPDATE is very easy
for users.Because we use a simple english words or Statements.
(iv) Store
Students marks evaluation details
We easily get our Evaluatiom marks details that is stored in DBMS of
Regional Center applications that is easily available for Enrolled Students.
(v) Store
Employee details.
If we want to Know the details about the any of the Employee then
we can easily get from the DBMS that is already stored in DBMS .To know which
Employee is responsible for the which work that is assigned by
Administrator.
(vi) Store final
year project Submission.
In IGNOU programmed application the students have
to create Project on any topics and the project is Submitted by Students in
Regional Center.If student want to see the details of submitted project , they
get from there.
(vii) Easy to
implement Security and integrity of data
DBMS has four methods to maintain data integrity:
normalizing data, defining business rules, providing referential integrity and
data validation. Data normalization is a process where unnecessary dependencies
and repeating groups of data are eliminated. Business rules for data access
control data handling and sharing between applications. Referential integrity
is used to protect data from corruption. Data validation uses multiple
processes to validate data in the application.
(viii) Fast access of
information
In DBMS, all
data of an organization is integrated into a single database file. The data is
recorded in only one place in the database and it is not
duplicated.Thorough which we can access of Information fast
(ix) Data
sharing in other department of IGNOU.
In DBMS, data can be shared by authorized users of the organization. The
database administrator manages the data and gives rights to users to access the
data. Many users can be authorized to
access the same piece of information simultaneously. The remote
users can also share same data. Similarly, the data of same database can be
shared between different application programs.
(x) Better data accuracy
By controlling the data redundancy, the data
consistency is obtained. If a data item appears only once, any update to its
value has to be performed only once and the updated value is immediately
available to all users. If the DBMS has controlled redundancy, the database
system enforces consistency and accurate.
