Database Management System | DBMS Tutorial

The collection of similar data in one place refers to a database. Let’s not confuse it with data. Data is a collection of information in the form of facts and figures. The database allows users to manipulate data according to their comfort.

This includes retrieval, insertions, and removal of data. It organizes data in tabular, graphical, and many more forms. The database management system is software to help users in managing data.

It provides an interface for the users to handle data in various forms. This may be during database creating or during the time of update. It also ensures that the data is safe all time while maintaining consistency.

Data Definition Language is the scheme that the system follows to see what data will look like in the database. Some famous database management softwares are – MySQL, Oracle, etc. The task of the database management system includes –

1. Data Updation – It is where all the changes in data are made. This may be the addition, removal, or modification of data.

2. Data Retrieval – It allows retrieval of the data from the database for application usage.

**3. User Administration **– It registers, monitors, maintains and enforces data all the time. This includes securing it, controlling it, managing its performance, and recovering information in case of failure.

History of Database Management System

  • Charles Bachman came up with the first DBMS system in 1960.
  • Codd by IBM’S Information Management System enters in 1970.
  • Peter Chen introduces the Entity-relationship model in 1976.
  • The Relational Model became a database component in 1980.
  • Object-oriented DBMS develops in 1985
  • The incorporation of object orientation in DBMS takes place in the 1990s.
  • A personal DBMS by Microsoft – MS access came out in 1991.
  • The first Internet database applications came out in 1995.
  • XML became relevant to database processing in 1997.

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

  • Master
  • Model
  • MSDB
  • Tempdb
  • Resource
Master
  • This database contains all the System level Information in SQL Server. The Information in form of Meta data.
  • Because of this master database, we are able to access the SQL Server (On premise SQL Server)
Model
  • This database is used as a template for new databases.
  • Whenever a new database is created, initially a copy of model database is what created as new database.
MSDB
  • This database is where a service called SQL Server Agent stores its data.
  • SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.
TempDB
  • The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
  • User can create their own version of temporary tables and those are stored in Tempdb.
  • But this database is destroyed and recreated every time when we restart the instance of SQL Server.
Resource
  • The resource database is a hidden, read only database that holds the definitions of all system objects.
  • When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.

What is a Database Management System (DBMS) - An Overview

A database is an organized collection of data, which can be modified, retrieved, or updated. The data, the DBMS, and the applications associated with them together form the database concept. The data, stored in the database, is in the row and column format, which is called a table. Every website, which needs us to sign up, uses a database. There is no Internet without databases.

Introduction to DBMS

A Database Management System (DBMS) is a software application that is used to create, access, maintain, and manage databases. We can install it like any other application and use [SQL] for all the operations we intend to perform on databases. A DBMS accepts the incoming data either from an application or from a user who is manually entering it.
