A multivalued field may also be known as a multivalued dependency. Techopedia Explains Multivalued Field The most well-known use of MVF was in Microsoft Access 2007. This is because Microsoft wanted to make sure that Access was as compatible as possible with another closely related Microsoft pro...

(a) What is a multivalued dependency in DBMS? (b) Give an example. What is data granularity? What does a big data architect do? What are the differences of storage architecture between DBMS and OODBMS? What is the difference between a database Field and a database Record?
In 4NFF, R should be (no multi-valued dependency exists). Unable to undergo lossless decomposition (join dependency) PJNF (Project-Join Normal Form) Example Consider the database tableRbelow having the schemaR (supplier, product, consumer). The primary key is a combination of all three attrib...
To understand why use of fuzzy logic has grown, you must first understand what is meant by fuzzy logic. Fuzzy logic has two different meanings. In a narrow sense, fuzzy logic is a logical system, which is an extension of multivalued logic. However, in a wider sense fuzzy logic (FL) is...
The first step in confirming 1NF is modifying multivalued columns to make sure that each column in a table does not take more than one entry. Searching records with duplicate entries is complex. To overcome this situation, all records involved in a relational database table have to be identifi...

1.Trivial FD– X -> Y is a FD and Y is subset of X 2.Non Trivial FD– X-> Y is a FD and Y is not subset of X 3.Completely Non Trivial FD– X->Y is a FD and X intersection Y is null 4.Multivalued dependency– X->->y , two independent attributes are both dependent on...
What are the types of dependencies in a database management system?There arefour types of database dependencies: trivial functional dependencies, full functional dependencies, transitive dependencies, and multivalued dependencies. How does functional dependency differ from transitive dependency?In database ...
Everything is imprecise if you look closely enough, but more than that, most things are imprecise even on careful inspection. Fuzzy reasoning builds this understanding into the process rather than tacking it onto the end. Fuzzy logic can model nonlinear functions of arbitrary complexity. ...
