Abstract
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.
