Key Difference between DBMS and RDBMS:
DBMS :
- In DBMS, data is generally stored in either a hierarchical form or a navigational form.
- This means that a single data unit will have one parent node and zero, one or more children nodes.
- It may even be stored in a graph form, which can be seen in the network model.
RDBMS :
- In a RDBMS, the tables will have an identifier called primary key. Data values will be stored in the form of tables.
- The relationships between these data values will be stored in the form of a table as well.
- Every value stored in the relational database is accessible. This value can be updated by the system.
- The data in this system is also physically and logically independent.
