Creating Business Intelligence Applications
Filter Web Parts can be very useful in data-rich business intelligence sites. They provide a user interface (usually, and can be hidden) that allows the user to provide search or filter criteria for a query on data such as a database table or a list. When you connect a filter Web Part to one or more Web Parts on the page that have filtering capability, they display filtered results of the query. This section provides conceptual and how-to information for writing and consuming your own filter Web Parts.
