My description covers integration with MySQL. As a result will be APEX application with Interactive Report and CRUD form based on MySQL data.
Description contains two parts: First part is a MySQL site, Second part is a APEX application part


Prerequisites:
Oracle 11g+APEX 18.1+MySQL/PostgresRestSQL
