In This DBMS Tutorial | Database Management System We Will Discuss About Database Management System and In Detailed About This
Database Management System (DBMS) :
DBMS Stand For Database Management System. It is a software and it is used to create and manage the data in the Database. DBMS is a set of programs that allow users to store, modify, update, and retrieve information from the database. DBMS provides security and protection to the database Because It has ACID Properties.
What is DBMS : It is a set of programs that permits user to form and maintain a info. In alternative words, its general computer code that has the users with the processes of shaping and constructing and manipulating the info for numerous applications.
What is a Database system?
The database and DBMS software together is called as Database system.
Like Example: MySQL, Oracle, SQL, DB2, Microsoft Access, MS SQL Server, etc … Which are different types of database management system.
Database Management System (DBMS) allows users :
Data Definition: It is Used to creation, modification and removal of definitions that define the organization of data in database.
Data Updation:It is Used to insertion, modification and deletion of the actual data in the database.
Data Retrieval: It is Used to retrieval of data from the database which can be used by applications for various purposes.
User Administration: It is Used to registering and monitoring users and enforcing data security, monitoring performance and maintaining data integrity, dealing with concurrency control and recovering information corrupted by unexpected failure.
Advantages Of Database Management System (DBMS) :
- Minimized redundancy and data inconsistency
- Easy to use to access the data from the database
- DBMS provides Backup and Recovery mechanism
- Reduces development time
- Multiple user interface
- Data sharing with Multiple users and Easily Maintance
Disadvantages Of Database Management System (DBMS) :
- Cost of Hardware and Software
- Large space of disks and large memory to run them efficiently
- DBMS is complex and time consuming to design
- Higher impact of failure
Characteristics of Database Management System (DBMS) :
- This is used to a digital repository established on a server to store and manage the data in database.
- DBMS can provide a logical view of the process which is manipulates data.
- It is Provides backup and recovery procedures automatically.
- It contains ACID properties which is maintaince the data in a the good state in case of failure.
- This can reduces the complexity relationship between data.
- DBMS can Used to manipulation and processing of data.
- Provides strongly security of data.
- DBMS Can view the database according to the requirements of the user from different viewpoints.

DBMS vs File System :
Different Between DBMS vs File System –
- It is a collection of data. In DBMS, not required to write the procedures for any time.
- Gives an abstract view of data.
- Provides protection mechanism.
- The database system is highly expensive to design it.
- Data Independence exists in this system.
- In it database approach, have 3 types of data models.
- This is also a collection of data. But In this system, the user has to write the procedures for managing the database at a time.
- Provides the details of the data representation with storage of data.
- It isn’t easy to protect.
- It is cheaper to design.
- In the File system approach, have no Data Independence
- In the file system approach, here is no concept of data models.
