/**
 *  The <b><code>DBFOschemafyMain</code></b> class serves as the core application 
 *  logic within a Java framework for generating OWL/XML ontologies: It
 *  leverages MySQL tables containing configuration details to
 *  construct the ontology structure. This class acts as the
 *  central controller, directing the overall process of ontology
 *  generation based on user-provided configuration data.
 *  <p>
 *  <b>Key Functionalities:</b>
 *  <p>
 *  Builds connection to the RDB
 *  <p>
 *  Controls ontology generation sequence. Orchestrates the creation
 *  of the ontology by calling dedicated modules responsible for:
 *  <ul>
 *  <li>Generating OWL header
 *  <li>Defining class structures
 *  <li>Setting class disjointness
 *  <li>Defining class annotations
 *  <li>Defining object properties 
 *  <li>Defining triplets (relationships between individuals)
 *  <li>Adding data properties and data property references
 *  <li>Adding OWL trailer
 *  </ul>
 *  <p>
 *  <p>
 *  Logs Console Messages: Provides informative messages during
 *  execution to track progress.
 *  <p>
