Section 4 presents an algorithm for classifying dependencies into full and partial and in section 5 we present the algorithms for the decomposition into 2NF and 3NF respectively.
The most important of them are 3NF (Third Normal Form) [2] and BCND (Boyce-Codd Normal Form) [3]), where BCNF is a stronger definition of 3NF.

C is the parallel capacitance and is equal to 3nF. From a netlist point of view, APLAC is evidently a SPICE-like simulator.
When the input set of data dependencies is a set of functional dependencies (or simply FDs) an appropriate normal form may be Second, Third, or Boyce-Codd Normal Form (abbreviated to 2NF, 3NF, and BCNF, respectively).
Flexibility is generally viewed from the architectural standpoint of a physical model based on third normal form (3NF), or the so-called "whole key," vs.
Boyce-Codd normal form (BCNF) was introduced by Codd (1974) to provide a normal form simpler than 3NF. Fourth normal form was introduced in Fagin (1977).
After normalizing the data (3NF), three files were in the final design:
So the Baton Rouge researchers compared twin nitro-PAHs featuring identical chemical compositions and reduction potentials: 3-nitrofluoranthene (3NF) and 1-phenyl-4-nitronaphthalene (1P4NN).
