One example of a collaborative application is a document management system. With such a system, you can store documents in public folders so that they are easily accessible by everyone in an organization. Employing search capabilities, you can perform searches of the document database to locate documents written on a particular date, or containing specific types of information. Using workflow, your application can route documents for approval prior to adding them to the database.
