Step One: Write the first SQL script to create Oracle database tables using SQL Data Definition Language $($DDL$)$ for each table listed in the metadata of Project $2.$ a$.$ Include DROP TABLE statements for each table at the script. b$.$ Ensure that referential integrity is established between related tables. Every table must have a Primary Key. Related tables must have Foreign Keys defined. These can be defined in ALTER TABLE statements later in the script. c$.$ At least one ALTER TABLE statement must be included in the first script. d$.$ Ensure all table constraints are properly defined such as PRIMARY KEYS, FOREIGN KEYS, etc. e$.$ Be sure to save your first SQL script that creates all of your tables with a $.$sql extension.
