Database
Management System (DBMS) is used by
the users to access the data stored in database files. A DBMS is also
used to perform administrative tasks on the databases and
objects contained within the database.
DBMS is a
collection of applications that allows users and other programs to capture and
analyze data by providing additional functionality like reporting services to
help you create,
deploy, and manage reports for your organization.
A RDBMS is a
software system designed to allow the definition, creation, querying, and
updating of data stored in relational databases.
A few examples
of RDBMS include; Microsoft SQL Server, Microsoft Access, and MySQL
Database servers
Databases are
stored on database servers which are dedicated physical or virtual servers that
host the database files and provide high-level performance for users who are
accessing the data.
Database
servers contain the DBMS used to manage the data and administer the SQL Server
environment.
A database
server can have one default instance and several named instances of SQL Server.
A SQL Server instance is a copy of
the sqlservr.exe program that runs as a Windows operating system service.
Often multiple
database servers are deployed to provide high availability and improve
performance
