Final answer:
A query datasheet is temporary and created based on the criteria specified in a structured query language. It allows users to view and interact with database information corresponding to the set parameters without modifying the actual data.
Step-by-step explanation:
A query datasheet is temporary, and its contents are based on the criteria you establish in the design grid. In database management systems, a query is a request for data or information from a database table or combination of tables. This query is usually written in a structured query language (SQL) and the result is presented in a datasheet view. Such datasheets are not stored as data within the database but are dynamically created based on the query parameters. They allow users to interact with the data, such as filtering or sorting, according to their needs without altering the underlying database records.
For example, imagine a student database where a college administrator wants to find all students who are majoring in Biology. The administrator would create a query with the major field set to 'Biology'. The resulting datasheet would display all students matching that criterion. If, later on, the administrator changes the query to find students majoring in Chemistry, the datasheet view would change accordingly, reflecting the new search criteria.
