Example text

An agent representing a user may request a broker to find an agent representing another external component such as a source or a resource. The broker will usually consult a directory service (itself controlled by an agent) to locate potential agents representing suitable sources or resources. The information will be returned to the requesting (user) agent, probably with recommendations as to order of preference based on criteria concerning the offered services. The user agent matches these against preferences expressed in the metadata associated with the user and makes a choice.

Otherwise we have a miss. Nodes that include documents that match the query are called matching nodes. 2 G. Koloniari and E. Pitoura Query Routing A given query may be matched by documents at various nodes. Thus, central to a P2P system is a mechanism for locating nodes with matching documents. In this regard, there are two types of P2P systems. In structured P2P systems, documents (or indexes of documents) are placed at specific nodes usually based on distributed hashing (such as in CAN [21] and Chord [20]).

In the following sections we discuss all these aspects. 1 Security for Structured Database on the web A lot of research has been done for developing access control models for Relational and Object-oriented DBMSs [6]. For example, today most of the commercial DBMSs rely on the System R access control model. However, the web introduces new challenges. For instences, a key issue is related to the population accessing web databases which is greater and more dynamic than the one accessing conventional DBMSs.
