The agents include Personalization agents, Evaluation agents, Query management agents, Feedback agents etc.
The second paper, entitled "Energy-efficient query management scheme for a wireless sensor database system" by Nan and Li, proposes an energy-efficient query management framework that copes with multiple queries in a sensor network.
In this framework, we propose a query management scheme to support query partitioning, region aggregation and approximate processing, time partitioning and aggregation rules, multirate queries, and historical database.
However, effective query management to optimize the query aggregation plan at the gateway side is also a significant approach to energy saving in practice.
The performance simulation results show that the overall energy consumption for forwarding and answering a collection of queries can be significantly reduced by applying our query management scheme.
The objective was to design and implement a digital library with all the tasks needed, like query management, automatic design and generation of electronic documents, selective information distribution, etc.
Post-study-visit (4): final query management.
Among other things, the comprehensive database management system supports participant recruitment, study monitoring, data safety monitoring, and query management.
Data management, query management and monitoring of the study will be done by the Coordination Center for Clinical Trials at the Martin Luther University of Halle-Wittenberg (KKSH).
The chosen options are then transformed into actual SQL formatted statements that are sent to the query management agent, through the PHP engine, as shown in Figure 8.
These procedures included preparatory meetings, site visits, close monitoring of data collection and data entry, concurrent query management, inconsistency checks, double data collection for selected medical charts, and the use of a detailed manual of operation.
