What are the differences between a DBMS and RDBMS?

ans:- DBMS RDBMS Provides an organized way of managing, retrieving, and storing from a collection of logically related information Provides the same as that of DBMS, but it provides relational integrity.

There are different types of DBMS products: relational, network and hierarchical. The most widely commonly used type of DBMS today is the Relational Database Management Systems (RDBMS)

DBMS:

• A DBMS is a storage area that persist the data in files.
• There are limitations to store records in a single database file.
• DBMS allows the relations to be established between 2 files.
• Data is stored in flat files with metadata.
• DBMS does not support client / server architecture.
• DBMS does not follow normalization. Only single user can access the data.
• DBMS does not impose integrity constraints.
• ACID properties of database must be implemented by the user or the developer

RDBMS:

• RDBMS stores the data in tabular form.
• It has additional condition for supporting tabular structure or data that enforces relationships among tables.
• RDBMS supports client/server architecture.
• RDBMS follows normalization.
• RDBMS allows simultaneous access of users to data tables.
• RDBMS imposes integrity constraints.
• ACID properties of the database are defined in the integrity constraints.

RDBMS: is a DBMS that is based on Relational model that stores data in tabular form.

• SQL Server, Sybase, Oracle, MySQL, IBM DB2, MS Access, etc.

Features:

• Database, with Tables having relations maintained by FK
• DDL, DML
• Data Integrity & ACID rules
• Multiple User Access
• Backup & Restore
• Database Administration
