What Is The Main Objective of Database Management Systems?
Organizations use considerable amounts of data. A database management program (DBMS) is a program which gives them every opportunity to arrange data in a database.
The standard abbreviation for database management program is DBMS, so you will often see this instead of the full name. The ultimate goal of a database management program is to shop and convert data into information to support selection.
A DBMS includes the following three elements: The actual database: the collection of data files that contain the data
The database engine: the application which gives them every opportunity to gain accessibility and change the material of the database
The database scheme: the requirements of the sensible framework of the details saved in the database
While it sounds sensible to have a DBMS in position, it is worth thinking for a short time about the alternative. What would the details in a business look like without a DBMS? Consider yourself as the business for a short time, and the details are all the data files on your pc. How is your details organized? If you are like most common people, you have a huge amount of data files, structured in files.
You may have word processor records, presentation data files, excel spreadsheets, pictures, etc. You find the important info based on the directory framework you are creating and the names you have given to your data files. This is called data program and is common for personal people.
Now consider the difficulties you are faced with. Have you ever lost a file? Have you had difficulty finding a file? Probably. Perhaps you are using several computer systems and your data files are located in different actual locations. And when was the list time you developed a back-up of all your files? You do support, right?
You probably get the picture. A data file program is relatively easy, but it only works if you keep yourself very structured and regimented. Now consider a business with 1,000 workers, each with their own pc. Can you see some of the difficulties when using data system? Do you really want critical financial data going around the offices as easy data files on personal computers?
Functions of a DBMS
So what does a DBMS really do? It arranges your data files to give you additional power over your details.
A DBMS gives them every opportunity for customers to develop, change and upgrade data in database data files. Once designed, the DBMS gives them every opportunity to shop and recover data from those database data files.
More specifically, a DBMS provides the following functions:
Concurrency: contingency accessibility (meaning ‘at the same time’) to the same database by several users
Security: protection guidelines to determine accessibility rights of users
Backup and recovery: processes to back-up the details regularly and recover data if a problem occurs
Integrity: database framework and guidelines improve the reliability of the data
Details descriptions: a knowledge vocabulary provides an explanation of the data
