Integration: Relational Databases

MySQL

Example

The following example is a simple database using a MySQL database. The Omnidex Environment File is displayed below; however, the entire example can be downloaded as a ZIP file at the following link: Download ZIP File. This ZIP file also includes files that can be used to create the MySQL database.

The following statements will create and build an Omnidex Environment against a MySQL database:

> use sql/create_all.sql
-> use sql/simple.sql
