In this paper we have focused on three major aspects relating to quality aware query systems, namely measuring data quality, modeling of user׳s data quality preferences, and answering the query in consideration of the defined preferences and measures.
This study proposes an adaptive method in consideration of an account user's preferences that are tallied, based on the frequency of user query requests during data dissemination.
Moreover the studied database consist also of 1000 legitimate websites which we collected ourselves by combining Alexa's [14] 500 top global website with 500 websites resulted from queries to google search engine, as for the queries we used to feed our database are (*.bank.*, *.commerce.*, *.trade.*) in consideration of the phishing attack and the websites more likely to be targeted.
This is because existing DBMSs, with general-purpose data management as the main purpose, have little consideration of the query types and user access patterns that are unique in MS data analysis.

This paper describes the design and implementation of the Data Quality Query System (DQ2S), a query processing framework and tool incorporating data quality profiling functionality in the processing of queries involving quality-aware query language extensions.
These advertisements may be targeted to the content of information stored on the services, queries made through the services, or other information". They go on to specify that Google can at any time modify or extend how and when advertising is delivered and that users must agree to let Google advertise in consideration for granting use of its services.
We provide three types of query functions depending on the type of filtering options: spatial queries, directional queries, temporal queries, and two types of queries in terms of query frequency (snapshot or continuous).
In June, Google accounted for 61.5percentt of search queries in the United States, dwarfing Yahoo, with 20.9percentt, and Microsoft, with 9.2percentt of queries, according to tracking firm comScore.
Our algorithms take into consideration a variety of query-processing techniques employed by mediators to enhance the set of supported queries, and they yield concise capability descriptions.
In Figure 3, the number of queries matching each one of the selected query types is plotted over time.
