Partial Dependency and Fully Functional Dependency Partial dependency : Suppose you have more than one attributes in primary key. Let A be the non-prime key attribute. If A is not dependent upon all prime key attributes then partial dependency exists. Functional Dependency is when one attribute determines another attribute in a DBMS system. Axiom, Decomposition, Dependent, Determinant, Union are key terms for functional dependency Four types of functional dependency are 1) Multivalued 2) Trivial 3) Non-trivial 4) Transitive Multivalued dependency occurs in the situation where there are multiple independent multivalued attributes in a single table The Trivial dependency occurs when a set of attributes which are called a trivial if the set of attributes are included in that attribute Nontrivial dependency occurs when A--B holds true where B is not a subset of A. A transitive is a type of functional dependency which happens when it is indirectly formed by two functional dependencies Normalization is a method of organizing the data in the database which helps you to avoid data redundancy Notes: http://www.tutorialsspace.com/Downloa...
