The typical components of a DBMS with a neat diagram
Components of DBMS
The database management system can be divided into five major components, they are:
Let's have a simple diagram to see how they all fit together to form a database management system.
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.
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 intrepret it into actual database commands to execute them on the DB.
