Abstract. The original vision of HyPer was to build an efficient com-
bined OLTP and OLAP system by exploiting modern hardware, in par-
ticular large main-memory capacities. This original design led to a num-
ber of further developments, inspired by both technology changes and a
broadening of the original goal. Key technologies were a powerful com-
pilation framework and a highly parallelized query processing engine.
This talk highlights the evolution and major development steps of HyPer
from a specialized research system to an industrial-strength database
system.
