Boyce Codd Normal Form | Normalization in Database DBMS | BCNF Decomposition Example | 4NF 5NF | 54 HD

Database, Normalization, 1NF, 2NF, 3NF, BCNF, DBMS, Example, Hindi, Database Normal Forms, If a relational schema is in BCNF then all redundancy based on functional dependency has been removed, although other types of redundancy may still exist. A relational schema R is in Boyce–Codd normal form if and only if for every one of its dependencies X ? Y, at least one of the following conditions hold X ? Y is a trivial functional dependency (Y ? X) X is a super key for schema R, Database Normalization - Explained with Examples,Normalization - 1NF, 2NF, 3NF and 4NF,Primary Key, SQL - Structured Query Language, NORMALIZATION - Organizing , Splitting Information to remove redundancy AND increase Consistency, JOIN - Combining Information from different tables, REDUNDANCY - Unnecessary data , Duplication, CONSISTENCY - Irrespective of how you access data you get same result, TRANSITIVITY - Derivation from multiple pieces of information). In normalization you split information in tables, To get the split information you need to use JOINS
