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
