What is the difference between relation and relationship in dbms?
Relationship is purely a construct of the er data model.Relation is a structure of the relational data model.
What is the need of rdbms?
A DBMS stores data in a table where the entries are filed under a specific category and are properly indexed. This allowed programmers to have a lot more structure when saving or retrieving data. A relational database contains data in more than one table. Each table contains a database that is then linked to other tables with respect to their relationships.

Difference between traditional and latest DBMS package?
Traditional FPS and DBMS both are different from each other. In DBMS there is security of data as well as integrated data while this is not in FPS.
Is there any difference between integrity and correctness of data in DBMS?
Yes, there is a difference. Integrity in DBMS refers to the accuracy and consistency of data, ensuring data follows constraints and rules. Correctness, on the other hand, refers to the accuracy of the actual data values stored in the database tables. In summary, integrity ensures data conforms to defined rules, while correctness ensures the data is accurate.
What is the difference between data model and schema in database?
As I understand it, a database schema is a physical entity, it describes the structure of exactly how the data is stored and is itself stored by DBMS for reference. Data model, on the other hand, is an abstract representation of database.
What is the difference between DBMS and GIS?
gis and dbms
What is the difference between controlled redundancy and uncontrolled redundancy?
Controlled redundancy refers to intentionally duplicating certain components in a system to ensure reliability and fault tolerance, whereas uncontrolled redundancy occurs unintentionally due to inefficient processes or lack of coordination. Controlled redundancy is planned and managed to enhance system performance, while uncontrolled redundancy can lead to inefficiencies and waste of resources.
What is the difference between drop and truncate in dbms?
even though both these commands are related to the structure of the table...,we can regain the data when we use use drop command by use of rollback command but its not possible in the case of truncate command.
What is the difference between active and passive data dictionary?
The integrated data dictionary is called active if it is checked by DBMS every time a data base is accessed. It is always consistent with actual data base structure. It is automatically maintained by the system.The integrated data dictionary is called passive if it is not used in day to day database processing.
What are the advantages of rdbms over dbms?
RDBMS is a Relational Data Base Management System Relational DBMS. This adds the additional condition that the system supports a tabular structure for the data, with enforced relationships between the tables. This excludes the databases that don't support a tabular structure or don't enforce relationships between tables.
What is difference between Schema and Subschema?
SCHEMA is the physical arrangement of the data as it appears in the DBMS. SUB-SCHEMA is the logical view of the data as it appears to the application program.
What are the difference between database systems and data information retrieval systems?
A database management system (DBMS or simply database) forms the back-end of a data information retrieval system. Data retrieval is just one component of a DBMS; data input, storage and maintenance being the other major components.
