News editors obtained the following quote from the background information supplied by the inventors: "A federated database is made up of a number of interconnected database management systems (DBMSs), each of which manages one or more databases. The federated database allows a single query to access the databases through the interconnected DBMSs. The query is received by the federated database and propagated over connections between the various DBMSs. DBMSs that control databases targeted by the query then translate the query into actions that are compatible with the databases they control.
"As the size of a database federation increases, various scaling problems can occur. For example, as new DBMSs are added to the federated database, the number of connections between the DBMSs may increase in a combinatorial fashion. This can lead to an unwieldy number of connections in a federated database that contains only a moderate number of DBMSs. Further, the network topology of the federated database may also lead to data that is inaccessible following the failure of a connection or DBMS. Additionally, when a query is made to the database federation, the communication overhead in distributing the query to all of the DBMSs can be significant."
As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventors' summary information for this patent: "A method for propagating a query in a system made up of a number connectable database management system nodes, where each node is associated at least one database, includes: selecting a first node from the number of nodes; generating at least one connection operable to propagate a query from the first node to a first subset of the number of nodes; generating at least one connection operable to propagate a query from a second node in the first subset to a second subset of the plurality of nodes; where at least one node in the second subset is different from nodes in the first subset. A system for propagating a query in a federated database includes a plurality nodes, each the nodes including at least one database; a determiner which selects a first node of the plurality of nodes; a generator which generates at least one connection between the first node and a first subset of the plurality of nodes and generates at least one connections between a second node and a second subset of the plurality of nodes; wherein at least one node in the second subset is different from the nodes in the first subset."
