Abstract
This paper presents a database model represented as a graph where each node is an active entity capable of receiving and processing data packages called tokens. This graph will be referred to as a dataflow graph. All requests are injected into the dataflow graph in the form of tokens which propagate through the graph by being replicated from one node to another. Thus computation proceeds in an asynchronous data-driven fashion.
This model permits a large number of independent processing elements to operate on the database simultaneously thus achieving a high degree of parallelism. Simulation results are included to demonstrate the system’s behaviour in relationship to the number of existing processing elements and varying system loads.
