GVSystems

Description

Each GreenVulcano^® ESB operation that requires an interface to an external application is defined within a channel. A channel is a grouping of operations. The operations can be grouped into a channel according to you prefer rule: usually operations are grouped by technology or external application to which interfaced, but the division of operation within the channel is completely arbitrary. A system is a group of channels.

GVSystems element contains only one Systems element. The Systems element contains one or more System elements, each System element contains one or more Channels. In each channel you can define the Operations.

The following table shows GVSystem attributes:

Attribute	Type	Description
type	fixed	This attribute must assume the value module.
name	fixed	This attribute must assume the value SYSTEMS.
