ALGORITHM
An algorithm is a set
of instructions designed to perform a specific task. This can be a simple
process, such as multiplying two numbers, or a complex operation, such as
playing a compressed video file.
A computer program
can be viewed as an elaborate algorithm. In mathematics and computer science,
an algorithm usually means a small procedure that solves a recurrent problem.
In computer
programming, algorithms are often created as functions. These functions serve
as small programs that can be referenced by a larger program. For example, an
image viewing application may include a library of functions that each use a
custom algorithm to render different image file formats.

DATABASE
A database is an organized collection of
data.[1] The data is typically organized to model aspects of reality in a way
that supports processes requiring information. For example, modelling the
availability of rooms in hotels in a way that supports finding a hotel with
vacancies.
Database management systems are computer
software applications that interact with the user, other applications, and the
database itself to capture and analyze data. A general-purpose DBMS is designed
to allow the definition, creation, querying, update, and administration of
databases. Well-known DBMSs include MySQL, PostgreSQL, Microsoft SQL Server,
Oracle, Sybase and IBM DB2. A database is not generally portable across
different DBMSs, but different DBMS can interoperate by using standards such as
SQL and ODBC or JDBC to allow a single application to work with more than one
DBMS. Database management systems are often classified according to the
database model that they support; the most popular database systems since the
1980s have all supported the relational model as represented by the SQL
language. Sometimes a DBMS is loosely referred to as a 'database'.

DATA
Is a set of values of qualitative or quantitative variables; restated, pieces of data are individual pieces of information. Data is measured, collected and reported, and analyzed, whereupon it can be visualized using graphs or images. Data as an general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing.
Raw data, i.e., unprocessed data, refers to a collection of numbers, characters and is a relative term; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data refers to raw data that is collected in an uncontrolled in situ environment. Experimental data refers to data that is generated within the context of a scientific investigation by observation and recording.
