Jun 2, 2021 · A transitive dependency in a database is an indirect relationship between values in the same table that causes a functional dependency. To achieve the normalization standard of Third Normal Form (3NF), you must eliminate any transitive dependency.

Mar 21, 2024 · When any attribute does not require primary key and can easily get value using another non-primary attribute then it is called as Transitive Dependency. Let's take an example, we have a table where we have columns of student roll number, name, city where student live, and zip-code of city .

A transitive dependency is any dependency induced by a different component, that in turn is directly or indirectly referenced by the program. E.g. a call to a log() function may induce a transitive dependency to a library that manages the I/O of writing a message to a log file.

May 15, 2024 · In the context of a database management system, data independence is the feature that allows the schema of one layer of the database system to be changed without any impact on the schema of the next higher level of the database system.

When an indirect relationship causes functional dependency it is called Transitive Dependency. If P -> Q and Q -> R is true, then P-> R is a transitive dependency. To achieve 3NF, eliminate the Transitive Dependency. <MovieListing> The above table is not in 3NF because it has a transitive functional dependency −.

Apr 3, 2025 · Transitive functional dependency in DBMS is the relationship between attributes (columns) of a database table. This occurs when the price of one property determines the price of another property through an intermediate (third) factor. Please refer types of functional dependencies for more details.
