Because most HOST systems are database supported systems, the primary data exchange between the HOST/ERP system and the ADVISE ES system can be performed very efficiently by using plain database transfer tables.
Most database management systems support the trigger and procedure programming, which is very useful to create cost effective event driven interface solutions. In contrast the interface software has to poll cyclically linked database tables or file-systems for changes, which lead to an unnecessary high traffic load at the network and the computer systems.
A direct connection between the databases is theoretically possible but in most cases not permitted in due to avoiding malfunctions in each particular productive system.
The solution concept below follows the thoughts above.
