A query-based distribution group is a new additional type of distribution group in Exchange 2003. This new type of distribution group provides the same functionality as a standard distribution group; however, instead of specifying static user memberships, a query-based distribution group allows you to use an LDAP query to dynamically build membership in the distribution group (for example All employees with a special group membership). Using query-based distribution groups we can reduce the administration costs dramatically. However a Query-based Distribution Group needs more Server resources like CPU power and RAM.
This is called a correlated sub-query.
It saves time if your new query uses the same fields as the existing query.
It is a query inside another query. Sometimes we might use one query to reduce down the amount of data to go through and then use another query based on the output of that query to get what you want. The first query is inside or nested in the first query.

Query-based information extraction involves extracting specific information from a text based on a predefined query. This can be done using techniques such as named entity recognition, part-of-speech tagging, and syntactic parsing to identify relevant information based on the query parameters. Natural language processing or machine learning algorithms can be used to match the query with the text and extract the required information.
Use Universal distribution groups in a multiple-domain environment. The membership of universal distribution groups is replicated to each global catalog server in each domain
performs an action on the table on which it is based

A query datasheet displays the results of a query operation, showing data based on specified criteria or calculations. A table datasheet displays the data in a table format, representing information stored in a database table. In essence, a query datasheet is derived from a table datasheet and is dynamic based on the query criteria.
they are distributed by many different groups based on territorial lines. beer distribution is not statewide for anyone, not even bud and miller.
The query processor in a distributed DBMS is responsible for receiving and analyzing queries from users or applications, determining how to execute the query across multiple distributed nodes, and coordinating the execution of the query to retrieve the desired data efficiently. It optimizes query performance by considering factors such as data distribution, network latency, and data transfer costs across distributed nodes.
A simple search is one based on a single term or criterion.
