What additional parameters or methods, besides determining the determinant, are needed to bring the table matrix to the Boyce-Codd form?

To bring a table matrix to Boyce-Codd Normal Form (BCNF), it is not enough to only compute the determinant. It is important to analyze functional dependencies and apply the following methods:

• Identify keys — find all candidate keys of the table.
• Check functional dependencies — identify all dependencies between attributes.
• Decompose the table — if a functional dependency violates BCNF (i.e., the left side of the dependency is not a superkey), the table should be split into two or more tables to eliminate anomalies.

Thus, besides computing the determinant (which helps determine whether a set of attributes is a key), the methods needed are:

• Analysis and verification of functional dependencies.
• Algorithms for table decomposition.

Example: if there is a dependency A → B, where A is not a key, then the table should be split into two: one with attributes A and B, and the other with the remaining attributes to satisfy BCNF.
