It is a well known fact that the information system or a proper system to manage all the information is necessary for the operation of any business today.
We live amidst information abundant society which is full of statistical and other data. In order to manage a large amount of data a management system is essential and therefore 'database management system' (DBMS) is formulated. This system is computer software designed indented to manage databases based on array of data models.In other words it can be said that a database management system is a set of software applications that together make it possible for organizations or businesses to stockpile, alter, and mine information from a database. A database management system can be found in places such as banks, ATMs, hospitals, libraries, and other organizations.
In fact the database management systems are used in many places in the day to day life. For instance, in the ATM that get cash out of every week it is a database management system. When a person books a ticket online by providing information, it is recorded in the database management system.There are several aspects in life that is linked and runs on a database management system. The personal computer or the laptop can have its own database management system that is the part of the inbuilt software.
This database is used to store information and is necessary for retrieving information easily. People also use spreadsheets that include a huge amount of data. Any time if it is required to fill up a spreadsheet with data and carry out a query in order to find and analyze data, it is easy by using the database management system. Once the query is complete it is time to view the report.Nearly all database management systems have a reporting task which is the final step in the data manipulation procedure. One of the main purposes of the database management system is to find out the data that is stored through easy query processes.
In other words, it is not necessary have a knowledge of precisely where all that data is in the system, provided that the database management system knows where it all is, it can deliver a report for you to peruse. A database management system is a set of software programs that is installed to control the organization, storeroom, running, and recovery of data in a database.Besides, a database management system presents the capacity for numerous different users to share data and process resources. A huge quantity of information that can be stored at any amount of places within the mainframe system is made possible through a database management system.
Some of the most common benefits of database management system are as follows: it enhances strategic use of corporate data, it aids in reducing the complexity of the organization’s information systems environment, minimises the errors that can occur through manual data storage, improves data integrity, security, and also reduces the maintenance cost.It is possible to protect the database from unauthorised usage by placing a password and therefore data security can be enhanced. For instance, in an organization an employee database can contain all the data about each and every employee working over there, but one group of users or the people who are involved in calculating the payment may be allowed to view only payroll data, while others such as counsellors or the social workers may be allowed access to only work history and medical data.One trendy illustration of this kind of multi-user database is seen in the Microsoft SQL Server.
It can be said that the functionality also broadens to a multi-user database. This kind of database management system under this situation would permit one user to run all functions in the database without having to know what other users are accessing from the same database.
