Research of Cooperative System for Drilling Design Based on Smart Client
The characteristics of current cooperative drilling design are analyzed, and a cooperative system for drilling design based on smart client was constructed. This system provides a cooperative design platform supported by computers for drilling engineering technicians to improve the efficiency of drilling design. There are several features in this system as following: firstly, users own two kinds of working statuses, such as, on-line and offline;secondly, this system supports concurrency operation for multi-users. Based on the traditional model of Role Based Access Control, an improved new model, which is Role-Based Access Control of Smart Client (RBACSC), is put forward for the realization of multi-users access control in the cooperative system based on smart client. This paper mainly studies these key technologies to realize the smart client, such as data cache processing, data concurrency, data synchronization and so on.
