Wolfgang Keller, AMB Generali Informatik
Wolfgang Keller has some 8+ years experience with access layers. Now a non-coding manager for AMB-Informatik in Germany, he spent much time documenting patterns for O/R mappers in a research project after he had written a C++ access layer for a large bank in the mid nineties. After that he came across access layers again when involved in the construction of a very big insurance system in Smalltalk and persistence popped up periodically ever since in his work as an enterprise architect for an insurance group, e.g. when some system performed too slow. Wolfgang runs a well known web site on database and other patterns and continues following the field as one of his "technical hobbies".
