KW - Datenbanksystem KW - HL7 KW - Medizinische Informatik AB - A communication server is often used in Germany to interface legacy systems. It handles the translation, duplication, and transmission of messages to all systems that might need this information. Based on the principles of "for every data there is only one master" and "information on demand" we have built an information server that reduces the messages required and simplifies the handling of messages, the update of data already sent compared to a communication server. It also allows to implement a security policy as required by the German data privacy legislature. SN - 0926-9630 UR - http://fhffm.bsz-bw.de/frontdoor/index/index/docId/841 IS - 68 ER -
