We introduce version 1.0 of the GemsTD benchmark suite and report the performance on several different architectures for the cases in this suite. TRITA-PDC-2003:2 • ISSN 1401-2731 • ISRN KTH/PDC/R--03/2--SE

Data Mining places specific requirements on DBMS query performance that cannot be evaluated satisfactorily using existing OLAP benchmarks. The DD Benchmark defined here provides a practical case and yardstick to explore how well a DBMS is able to support Data Mining applications. It was derived from real-life data mining tasks performed by our Data SurveyorTM tool running on a variety of DBMS b...

this paper examines the effect of systematic risk on accounting conservatism. the idea is that in firms with higher systematic risk, managers have higher incentives to delay the recognition of bad news in the hope of future good news. they also face less demand for conservatism from investors and auditors. in this paper, for measuring systematic risk and accounting conservatism, we used beta fr...

With standardization e orts of a query language for XML documents drawing to a close, researchers and users increasingly focus their attention on the database technology that has to deliver on the new challenges that the sheer amount of XML documents produced by applications pose to data management: validation, performance evaluation and optimization of XML query processors are the upcoming iss...

We present a graph processing benchmark suite with the goal of helping to standardize graph processing evaluations. Fewer differences between graph processing evaluations will make it easier to compare different research efforts and quantify improvements. The benchmark not only specifies graph kernels, input graphs, and evaluation methodologies, but it also provides optimized baseline implement...

In the context of benchmarking XML implementations, several XML benchmarks have been produced to either test the application’s overall performance or evaluate individual XML functionalities of a specific XML implementation. Among six popular XML benchmarks investigated in this article, all techniques rely on code-generated datasets which disregard many of XML’s irregular aspects such as varying...

This article presents ERB, the ESA Ravenscar Benchmark. ERB aims at providing a synthetic benchmark comparing the efficiency of various Ada Ravenscar implementations and the RTEMS C implementation featuring the native threading model. ERB is original compared to existing Ada benchmarks, such as the ACES or the PIWG, not only because it is the first Ada Ravenscar benchmark, but also because it p...
