This benchmark uses an open-source database written in pure Java. It is synthesized with business logic to stress the BigDecimal library. It is a direct replacement to the SPECjvm98 db benchmark but is more capable and represents as close to a "real" application. The focus of this benchmark is on BigDecimal computations (based on telco benchmark) and database logic, especially, on locks behavior. BigDecimal computations are trying to be outside 64-bit to examine not only 'simple' BigDecimal, where 'long' is used often for internal representation.
