Decomposition Without Dependency Preserving If the decomposition of relation R with FDs (F), into R1
Dependency Preserving Decomposition As we know, table decomposition should be either lossless or dependency-preserving to
Lossless Decomposition If the information is not lost from the relation that is decomposed, then
Relational Decomposition When a table in the relational model is not in appropriate normal form,
Important Points Of Normal Forms As we know, normalization is used to remove the redundancy
Fifth Normal Form (5NF) The Fifth normal form (5NF) is generally not implemented in real-life
Fourth Normal Form (4NF) According to the fourth normal form (4NF), A relation will be
Boyce Codd Normal Form (BCNF) BCNF is extension of 3NF. It is stricter than 3NF.
Third Normal Form (3NF) A table will be in the third normal form (3NF) when,
Second Normal Form (2NF) Before to learn 2NF, 3NF, BCNF, 4NF and 5NF you must
First Normal Form (1NF) According to first normal form (1NF), The table should not contain
