Multivalued dependency occurs when two attributes in a table are independent of each other but, both depend on a third attribute. A multivalued dependency consists of at least two attributes that are dependent on a third attribute that's why it always requires at least three attributes.
Jun 13, 2024 · In Database Management Systems (DBMS), multivalued dependency (MVD) deals with complex attribute relationships in which an attribute may have many independent values while yet depending on another attribute or group of attributes.
Multivalued dependency would occur whenever two separate attributes in a given table happen to be independent of each other. And yet, both of these depend on another third attribute. The multivalued dependency contains at least two of the attributes dependent on the third attribute.
May 15, 2024 · In Database Management Systems (DBMS), multivalued dependency (MVD) deals with complex attribute relationships in which an attribute may have many independent values while yet depending on another attribute or group of attributes.
Multivalued Dependency. The termMultivalued Dependency refers to having several rows in a particular table. As a result, it implies that there are multiple other rows in the same table. A multivalued dependency would thus preclude the 4NF. Any multivalued dependency would involve at least three table attributes.
Dec 22, 2023 · Multivalued dependency (MVD) occurs when two attributes (B and C) in a table independently depend on a third attribute (A). This means A's value determines multiple values for both B and C. It's a complex relationship that can impact database normalization and integrity.
Oct 23, 2024 · A multivalued dependency exists in a relation when, for every value of one attribute (say A), there is a set of values for another attribute (B) that remains independent of the other attributes in the table.
Jul 31, 2023 · Multivalued Dependency (MVD) in a database management system (DBMS) is a concept that involves the existence of multiple rows in a single table. This means that one row in a table implies the existence of multiple other rows in the same table.
Apr 17, 2023 · A Multivalued dependency in dbms exists between two sets of attributes X and Y in a relation R if and only if there are two other sets of attributes A and B, where X ⊆ A ⊆ R and Y ⊆ B ⊆ R and A and B are not functionally dependent on each other, but they are functionally dependent on X.
In the field of database management systems (DBMS), multivalued dependency refers to a specific type of relationship between attributes or columns in a database table. It helps to ensure data integrity and minimize redundancy in the database.
