Database Reference
In-Depth Information
• The
Account Receivable
(
AR
) part of OEBS is concurrently accessed by many
internal modules, including the frontend.
• Every invoice object alteration in an AR domain is controlled by service agents,
propagating change state to
Business Event System
(
BES
) for event recognition
and filtering. The BES validates the type of event and helps constructing the
Event XML message, if the event is business, as well as message-oriented.
• A very small XML message with the event data is sent to the event subscriber,
which is a part of the message-oriented middleware.
• Service-subscriber pass the event particulars to the data-extraction module, which
queried AR DB for the invoice object.
• The Invoice Object is extracted from OEBS and transformed in the required
format.
