Your inventory CFC does not contain any instance data, and thus would be a
good candidate for placing in the application scope.
To help you understand the difference, consider the following CFC:
<cfcomponent>
<cfset variables.myname = "" />
<cffunction name="init">
<cfreturn this />
</cffunction>
<cffunction name="setName">
<cfargument name="myName" />
<cfset variables.myname = arguments.myname />
</cffunction>
<cffunction name="getName">
<cfreturn variables.myname />
</cffunction>
</cfcomponent>
If this CFC was placed into the application scope, you would run into race
conditions. This sequence could happen if this CFC was placed in a shared
scope: User A calls setName("Rich"), User B calls setName("Vince"), User A
calls getName() and is returned "Vince".
Since your CFC does not contain any instance data, it can safely be placed
in a shared scope.
HTH,
Rich
