The inference rules in DBMS describes the New functional Dependency derived from two existed entity which are functionally dependent.
For example: let two entities X and Y, if X belongs to Y and Y belongs Z then X must belongs to Z. This rule called transitive rule.

Inference rules in database management systems are logical rules used to deduce new information from existing data in databases. They help to generate new facts based on the relationships and constraints defined in the database. Inference rules can be used for data validation, query optimization, and improving data consistency and integrity.

What are three types of dbms?
Three types of DBMS (Database Management Systems) include relational DBMS, object-oriented DBMS, and NoSQL DBMS. Relational DBMS organizes data into tables with rows and columns, object-oriented DBMS stores data as objects and classes, and NoSQL DBMS handles unstructured and semi-structured data with flexible schemas.
What is the fullform of DBMS?
The full form of DBMS is Database Management System.
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 inference?
Logical interpretation, based on factual knowledge, and experience.An inference is the term given to a statement that may not be true, but was based on evidence collected.You mean an inference- it is a term used to describe a conclusion arrived at on the basis of evidence and reasoning.
What is the difference between flat file and DBMS?
A flat file is a simple file containing data without any structured format, while a Database Management System (DBMS) is a software system that manages databases by organizing, storing, and retrieving data. A DBMS allows for more organized and efficient data management, supports relationships between data, and provides features like security and data integrity that are not available with flat files.
How Armstrong rules are complete or sound in dbms?
Armstrong rules are complete or sound in dbms by clarifying the types of situations which need to be achieved and done.

What are the rules for dbms to become rdbms?
If a dbms follows more than 7 codes rules than it become rdbms.oracle follows 10 rules which is considered as ideal rdbms.no rdbms exist till now which follows all the 12 codes rules.
What are the basic concepts of DBMS?
DBMS stands for DataBase Management System. The main concepts are the structure, the manipulation, and a set of integrity rules.
When dbms becomes rdbms?
A DBMS becomes an RDBMS when the data contained in its tables are related to one another by referential integrity rules. DBMS - Database Management System RDBMS - Relational Database Management System

What is inference rules in artificial intelligence?
Inference is the act or process of deriving logical conclusions from premises known or assumed to be true.The conclusion drawn is also called an idiomatic. The laws of valid inference are studied in the field of logic.Or inference can be defined in another way. Inference is the non-logical, but rational, means, through observation of patterns of facts, to indirectly see new meanings and contexts for understanding. Of particular use to this application of inference are anomalies and symbols. Inference, in this sense, does not draw conclusions but opens new paths for inquiry. (See second set of Examples.) In this definition of inference, there are two types of inference: inductive inference and deductive inference. Unlike the definition of inference in the first paragraph above, meaning of word meanings are not tested but meaningful relationships are articulated.
