A study of distributed database system on Petri-net
Xin Liu · 2004
In this paper,we studied all sorts of distributed database design methods in detail. With Petri nets theory,object oriented technology and data structure, we introduced Petri nets practical distributed database design tools methods and discuss its designing process and realizing mothds.The tools is practice-oriented, adopting top-dowm analysis method, to finish requirement analysis, the relation model standardize, the data fragmentation and distributed. As a result, we supply a set reasionable design scheme of distributed database for the users. The tools is acqired by general distributed database design scheme,it can be used for the design of information system in various areas. This tools will play a positive role in promotion and application of distbuted database.
