Privacy-preserving comparisons over encrypted database is a hot topic in the current academic research. Recently, Furukawa [7] introduced a new primitive called request-based comparable encryption (comparable encryption for short) to achieve this target. Howver, one disadvantage of comparable encryption is that huge of the token and cipher text are required in the scheme and thus the computation and...
TPC-DS is a new generation industry decision support system benchmark. In this paper, we propose a configurable architecture and discuss key technologies for TPC-DS testing tool development.By testing practices in different DBMSs and the same DBMS with various configurations,authors prove the availability of our implementation strategies.
Aim to the intelligentized aid industrial design method based on product semantics, bring forwards the vague expression way of product semantics, discuss the technique to get the product semantics by tests, founds the product multidimensional semantics space and the industrial design method based on it, establish a framework of CAIDS which is based on product semantics-aided.
