WebbThe procedure of distributed query processing (Fig. 1) follows the approach of conventional query processing in database systems: In the first phase, a given query is parsed and translated into an internal representation (e.g., a query graph with nodes representing operators of an extended relational algebra). Webbreliability. Distributed database systems (DDBS) and distributed computing systems (DCS) differ in the resources to be shared. DCS share hard disks and printers etc. while DDBS distribute data, where the data as well as operations on the data items are equally important [3] .
