ASx is based on a highly modular design, with the ASx core being
completely isolated from the environment in which it exists. The core accepts incoming
messages, processes them using the configured business logic and passes them out
again, either for further processing or by way of a reply to the initiator of the
message.
|
The integrity of the messages that represent transactions is maintained
using APx, our transaction management sub-system. APx is a stand-alone component
part of ASx that can be configured to interact with third-party transaction management
products, for example, when enterprise-wide transaction protection is required.
Since maintaining transaction integrity relies upon the correct operational state
of ASx as a whole, APx is also responsible for maintaining ASx system integrity.
The HotSync module maintains the data integrity network-wide, between multiple ASx
nodes. For more information on HotSync, please select the menu option.
The APx operating system interface shields ASx from the operating system upon which
it executes by providing a standard interface for ASx to use across all operating
systems.
The ASx database interface is used by the rest of ASx to manage data. The appropriate
module version is supplied dependent upon which database is selected by the customer.
Once again, a standard interface is provided across all databases.
|
The device driver interface provides a common channel interface
to the devices and networks connected to ASx. This module range supports the protocols
of the device and network connections directly. Access to communication transport
is through the communication interface.
The communications interface enables the whole of ASx to access the various supported
communication protocols on the target operating system in a standard environment
independent manner.
