A word on naming conventions: Since Magento 1.6, the setup
script naming conventions have changed. Originally, the Mysql4-
install-x.x.x.php naming convention was used and is currently
deprecated but still supported.
Since Magento 1.6, the naming convention for the setup script has changed and now
developers can make use of three different script types:
• Install: This script is used when the module is first installed and no record of
it exists on the core_resource table
• Upgrade: This script is used if the version in the core_resource table is
lower than the one in the config.xml file
• Data: This script will run after the matching version install/upgrade script
and are used to populate the tables with required data
Data script are introduced in Magento 1.6 and are stored under
the data/directory directly under our Module root. They follow a
slightly different convention than the install and upgrade scripts
by adding the prefix.

The file location is app/code/local/Mdg/Giftregistry/sql/mdg_giftregistry_
setup/install-0.1.0.php. Refer to the following code:
