The Simple Google Maps module for Drupal is a field formatter which displays a map using Google Maps.
All you have to do is, create a text field to store the address and configure the Simple Google Maps field formatter in the manage display section.
The geocoding, converting an address to longitude and latitude coordinates, is handled by the Google Maps API when the formatter is rendered. Drupal will not store the geographical coordinates for each address. If you need to store coordinates in the database look at the Geofield module.
In this video, I’ll show you how to store an address and display a map in a few easy steps.
