Database Management System (DBMS) is a database as information stored on a computer that which is used to record, maintain and retrieve data. It is an organized collection of a database. Common database structures are hierarchical, network, relational and object-oriented based & most widely used relational database for web applications.
The database management system can be divided into five major components, they are:
DBMS Components: Hardware:
When we say Hardware, we mean computer, hard disks, I/O channels for data, and any other physical component involved before any data is successfully stored into the memory.
When we run Oracle or MySQL on our personal computer, then our computer’s Hard Disk, our Keyboard using which we type in all the commands, our computer’s RAM, ROM all become a part of the DBMS hardware.
Database Management System Components: Software:
This is the main component, as this is the program which controls everything. The DBMS software is more like a wrapper around the physical database, which provides us with an easy-to-use interface to store, access and update data.
The DBMS software is capable of understanding the Database Access Language and interpret it into actual database commands to execute them on the DB.
DBMS Components: Data:
Data is the resource, for which DBMS was designed. The motive behind the creation of DBMS was to store and utilize data.
In a typical Database, the user-saved Data is present and metadata is stored.
Metadata is data about the data. This is information stored by the DBMS to better understand the data stored in it.
For example: When I store my Name in a database, the DBMS will store when the name was stored in the database, what is the size of the name, is it stored as related data to some other data, or is it independent, all this information is metadata.
DBMS Components: Procedures:
Procedures refer to general instructions to use a database management system. This includes procedures to setup and install a DBMS, To log in and log out of DBMS software, to manage databases, to take backups, generating reports etc.
