Over the years, I have written a pretty extensive shopping cart/back end 
processing application using TeraScript. The application handles multiple web 
sites with a separate MySQL database for each web site. All databases are 
running under one MySQL service with the One File per Table option enabled. 
This option makes InnoDB to store each created table into its own .ibd file.

Each web site/database has an Inventory table. I would like to share the 
Inventory table from one site with another site. I use many JOINs and LEFT 
OUTER JOINs when reading the inventory table.

I could look through all my tafs and tcfs for all INSERTS, UPDATES and DELETES, 
add code to update each other's table and keep the separate Inventory tables 
identical, but I am looking for a better solution.

I could pull the Inventory table out of the database and make the table it's 
own database that both sites access, but I am not sure if JOINs and LEFT OUTER 
JOINs would work.

Is there a way in MySQL to have one database look to another database for a 
table instead of it's own?

Or any other strategies you might recommend?

Thanks in advance
