Data refers to raw inputs that become meaningful when processed or organized into information. A database is a collection of organized data that meets users' needs. A database management system is a set of programs that allows users to store, modify, and extract information from a database. Examples of databases include computerized library systems, ATMs, flight reservation systems, and computerized parts inventory systems. Queries are used to request specific information from a database in the form of stylized questions.

Data, Information & Database

2. What is Data?
Data refers to the lowest abstract or a raw input
which when processed or arranged makes meaningful
output. It is the group or chunks which represent
quantitative and qualitative attributes pertaining to
variables.
Examples :of data can be facts, analysis, or
statistics. In computer terms, symbols, characters,
images, or numbers are data. These are the inputs
for the system to give a meaningful interpretation. In
other words, data in a meaningful form is
information.

3. Information
The raw input is data and it has no significance when it
exists in that form. When data is collated or organized into
something meaningful, it gains significance. This meaningful
organization is information.
Information is usually the processed outcome of data. More
specifically speaking, it is derived from data.
Information can be explained as any kind of understanding
or knowledge that can be exchanged with people. It can be
about facts, things, concepts, or anything relevant to the
topic concerned.

4. What is database?

 A group of programs that manipulate the database and provide
an interface between the database and the user of the database
or other application programs is known as Database Management
System.
 A collection of programs that enables you to store, modify, and
extract information from a database. There are many different
types
of DBMSs, ranging from small systems that run on personal
computers to huge systems that run on mainframes. The
following
are examples of database applications:
 computerized library systems
 automated teller machines
 flight reservation systems
 computerized parts inventory systems

5. Continued…..
 Requests for information from a database are made in the
form of a query, which is a stylized question. For
example, the query
SELECT ALL WHERE NAME = "SMITH" AND AGE > 35
requests all records in which the NAME field is SMITH
and the AGE field is greater than 35.
