Why to Learn DBMS?

DBMS (Database Management System) plays a major role in software engineering. In each industry, from smaller firms to higher-level organizations which uses softwares, must need DBMS for data management which can be only operated by a person who knows DBMS very well. So there are huge opportunities for the people who have a better knowledge of DBMS. DBMS helps businesses to better organize their data by providing various features like :

  • Real world entities
  • Table creation based on relations
  • Data isolation & protection
  • Consistency
  • Less redundancy
  • Query processing

Applications of Database Management System

In this Database tutorial, we will learn how a Database Management System (DBMS) is used in various sectors with applications like :

  • Banking: for storing customer information, account activities, deposits, payment details, loans, etc.
  • Manufacturing: for supply chain management, production tracking and inventory management
  • Finance: for storing information about stocks, sales, and purchases of financial instruments like stocks and bonds
  • Universities: for student information, course registrations, payroll and grades
  • Airlines: for reservations, ticket booking and schedule information

Advantages of DBMS

  • DBMS offers various techniques and powerful functions to efficiently store & retrieve data
  • DBMS serves as an efficient handler to balance the needs of multiple applications using the same data
  • Provides Uniform administration procedures for data management
  • Application programmers never exposed to details of data representation and storage
  • Offers Data Integrity and Security
  • DBMS implies integrity constraints to get a high level of protection against prohibited access to data
  • DBMS schedules concurrent access to the data in such a manner that only one user can access the same data at a time
  • Reduces Application Development Time

Disadvantages of DBMS

  • Hardware and Software cost of a DBMS is quite high which increases the budget of your organization
  • Most database management systems are often complex systems, so the training for users to use the DBMS is required
  • In some organizations, all data is integrated into a single database which may cause the damage because of electric failure or database can be corrupted on the storage media
  • Use of the same program at a time by many users sometimes lead to the loss of some data
  • DBMS can't perform sophisticated calculations

DBMS Notes

In the above Database Management System tutorial, we have covered following topics:

  • Full-Form: Database Management System
  • DBMS: is an application designed especially to enable user interaction with the software application
  • DBMS Users: Application Programmers, Database Administrators & End-users
  • Applications: Banking, Finance, Education, Medical, Airlines, etc.
  • Advantages: Data isolation, Data Security/Protection, Integrity, Consistency, Less redundancy
  • Disadvantages: Higher cost of hardware/software & training, Complex system, Data loss, Can’t perform sophisticated calculations
