One available product differs significantly from the others because it is not connected to a particular database management system and its query processing
does not result in direct execution of database commands.
However, data encryption imposes a significant amount of overhead during the query processing
phase, mainly due to the limitation of directly executing operations over encrypted data.
Top-K Based Query Processing
(Top Ranked Values on each Cluster), Necessary Set Based Query Processing
(Values Should be Present), Sufficient Set Based Query Processing
(Values that are more than enough)and Boundary based Query Processing
(Ranked values in a range.
reducing the number of paths pursued during query processing
While processing the containment queries, the methodology of filtering-and-verification approach is adopted to reduce the size of candidate graphs set, but the inclusion logic which is used in subgraph query processing
can not be applied.
First, the much larger amount of memory addressed by the Itanium 2-based Unisys ES7000 means faster builds of OLAP cubes and much faster query processing
The linguistic analysis, query processing
and distribution quality assessment functions are innovative and powerful.
The result is, the company claims, about a 50-times speed-up in query processing
If the distributed search interface is sufficiently intelligent to recognize the limitations of constituent systems, it may be able to compensate for at least some of these shortcomings by doing additional query processing
prior to presenting a result to the user at a significant performance penalty.
However, since it is infeasible or difficult to keep a high-speed and always-on connection between the sensor networks and the base station, maintaining such in-network data storing and query processing
in remote and tough environments is a necessary.
In Big Data, the amount of data outgrows with the capabilities of query processing
0 adds support for distributed query processing
, which boosts embedded database speed and scalability by taking advantage of the processing power, memory and bandwidth of multiple hardware nodes in conducting queries.
