With the development of the grid technology used in business field, it becomes more and more important to preserve privacy in information sharing field. This paper proposes a privacy-preserving query middleware PPQM based on credible third party in grid database, and fulfill privacy-preserving checking algorithm in PPQM to make privacy-preserving optimization of query plan before query assignment,...
As the development of the grid technology, it becomes more and more important in commerce application to preserve privacy and prevent information from being leaked when querying in a dynamic and heterogeneous grid database. This paper proposes a privacy-preserving query middleware PVOM (privacy-preserving visual organizations mediator) based on the security requirement of heterogeneous grid nodes,...
Grid database is a new research area combined with the database techniques and Grid techniques, while traditional database query and optimization techniques couldn't fully satisfy the need of Grid database because of the dynamic properties of Grid Nodes. The paper brings forward cost model in dynamic grid database environment , and also gives the dynamic query optimization algorithm used for the query...
Grid database is a new research area combined with the database techniques and Grid techniques, while traditional database query and optimization techniques couldn't fully satisfy the need of Grid database because of the dynamic properties of Grid Nodes. The paper brings forward a query plan model/ NSN based on Petri net so as to describe the data relation between subquery and nodes. Based on NSN...
