This led to many different proposals that had did not succeed in making a significant impact on SQL-compliant DBMS. More recently however, there has been significant interest and progress on event sequences, leading to vendor-proposed extension...
State-based representations of concurrent systems suffer from the well known state explosion problem. In contrast, Petri nets are good models for this type of systems both in terms of complexity of the analysis and in visualization of the model. In this paper we present Genet, a tool that allows the derivation of a general Petri net from a state-based representation of a system. The tool supports...
