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.

The full form of DBMS is Database Management System.
Integrity refers to the structure of the data and how it matches the schema of the database. Correctness could refer to either the integrity of the data or its accuracy (for example, a phone number being incorrect).
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.
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.
Armstrong rules are complete or sound in dbms by clarifying the types of situations which need to be achieved and done.
Define the two principle integrity rules for the relational modelDisscuss why it is desirable to enforce these rules also explain how DBMS enforces these integrity rules?
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.
DBMS stands for DataBase Management System. The main concepts are the structure, the manipulation, and a set of integrity rules.
Yes, rules of inference are valid inferences that guarantee truth-preservation. This means that if the premises of an argument are true, then the conclusion drawn using valid rules of inference will also be true. Rules of inference are based on sound logic and deductive reasoning to ensure that the conclusion accurately follows from the given premises.
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

Inference involves drawing conclusions based on evidence and reasoning, while deduction involves reaching a specific conclusion based on a set of premises or rules.
