To Web-enable your database, you must first mount the database using the Gatsby Design Assistant. The Gatsby Design Assistant tells Gatsby how to connect to your database.
Once the database is mounted, you can configure how the database is exposed. You can determine which database objects are exposed, give them user-friendly names, define keys, lookups and variety of other useful characteristics.
Once the database is working the way you like through Gatsby Database Explorer, you can use the techniques described in the Gatsby Programmer's Guide to incorporate the Gatsby's views directly into your site.
