/**
 * The purpose of this class is to show tables and indexes can be created using
 * QLDB java driver and how to load the sample data.
 * We use three actions do that:
 *
 * <ol>
 *     <li>CreateTables</li>
 *     <li>CreateIndexes</li>
 *     <li>LoadSampleData</li>
 * </ol>
 *
 * We start by  creating the tables using "CREATE TABLES" query of QLDB.
 * Once all the tables are created, we create the indexes on them using
 * "CREATE INDEX" query of QLDB.
 *
 * After the above two steps are completed, we load the sample data into the
 * tables
