Explain the difference between DBMS and RDBMS. - DBMS offers organized way of storing, managing and retrieving information.
- RDBMS provides all features of DBMS with added referential integrity concept. Explain the difference between DBMS and RDBMS.1) DBMS:
- A DBMS is a storage area that persist the data in files. To perform the database operations, the file should be in use.
- Relationship can be established between 2 files.
- There are limitations to store records in a single database file depending upon the database manager used.
- 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
2) 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.
