Thus in Table 1 there is join dependency; therefore in 5NF or PJNF, Table 1 is not. Table 2, Table 3, and Table 4, however, satisfy 5NF as it has no multivalued dependence and can not be further decomposed (join dependency does not exists). But this may not be valid in all ...
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...

4.Multivalued dependency– X->->y , two independent attributes are both dependent on a third attribute. Occur in a relation with three or more attributes. 5.Transitive Dependency– X->Z is a FD, and the following properties hold a) X->Y ...
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...
What function does an attribute of an entity perform in a DBMS? (a) What is a multivalued dependency in DBMS? (b) Give an example. If a database contains two identical records, will that necessarily have a negative effect on the integrity of the database? Why or why not...
