In a previous course, you created a script file with the SQL statements needed to create the tables in your COIN database, complete with additional indexes and constraints. In this exercise, you will write a script that will make one of the tables an
index-organized table. The table you should create is the COIN table, and it contains the following columns:
- coin_id: NUMBER
- coin_date: DATE
- mint_mark: VARCHAR2(20)
- series: VARCHAR2(20)
- denomination: VARCHAR2(10)
- variety: VARCHAR2(20)
- grade: VARCHAR2(10)
- owner_client_id: NUMBER
- country: VARCHAR2(20)
