JM Family                                                                                           
Senior Data Architect

JM Family is the importer of all Toyota and Lexis auto’s in the south east region.  Their objective was to migrate packages off a mainframe to different packages in UNIX environments.  All packages needed to exchange data in a real time Service-oriented architecture (SOA) utilizing Simple Object Access Protocol (SOAP) to do the message transferring. IBM MQ was used to que the transactions once they arrived at the target application.  This was all done through a datahub that utilized Informatica for pulling the mainframe data and loading to the datahub.  This 24-month project had two areas of responsibility that were performed by 2 separate people.  The hardware software implementation was handled by one of the people and Mr. Geiwitz was responsible for the Data Architecture and moving the data.  His team consisted of 10 developers.
