Dynamic profiles are central to the field specialization process. Runtime profiles are used in the first five steps in the Field Specialization process to identify attractive specialization opportunities, by successively narrowing down the scope to individual functions or...
This is like a koan: the performance benefits from field specialization are simultaneously independent of workloads used to generate that specialization and intimately aware of details of the workload it is speeding up.
Recall that field specialization generates, at compil...
Recall that a spiff is code added to the DBMS source that, given values of invariants known in cold code, generate specialized code (termed “speccode”) that will be called in hot code when the query is executed. How big are they?...
Our field specialization process proceeds through nine basic steps, supported along the way with proprietary tools that can contend with code bases comprised of millions of lines of source code....
The Arizona Commerce Authority has just announced that Dataware Ventures is one of the 25 semi-finalists for the Fall 2015 Arizona Innovation Challenge, and one of only two from Tucson.
For more details and a listing of all 25 semi-finalists, please see: http://www.azcomm...
DBMSs are by their nature very general: they can handle whatever schema is specified, any data that is consistent with that schema, and any query or modification that is presented. Such generality and efficiency have enabled their proliferation and use in many domains....
Most organizations with non-trivial data processing needs—including virtually all medium and large businesses and corporations—rely on enterprise application software (EAS), e.g.,CRM, SCM, and ERP, for their data processing and analysis. These EAS applications generall...
