基于工作流模式的水电厂安全信息管理系统的设计

摘要

According to the character of hydropower plant safety information management, analysis of resource sharing and the importance of data security, to resolve the past Hydropower C/S mode data access limitations, the design of three-tier structure based on B / S mode The hydropower plant information management system security program implementation. This program based on the original two-tier B/S model, Business Logic Tier is increased, so that makes applications and data services can be linked closely. Gives a feasible, reliable, efficient technology sustain to improve the data security of user-level and record-level, what's more, provide technical support on access control of workflow system.
　　The workflow platform technology used in hydropower plant security information management system, according to advantage of three-tier B/S model, in accordance with Security Information Management Hydropower workflow features of a task-based Access Control Model, will be the role, mandate, powers and tasks authorized by state as a control object, so the workflow state-wide, dynamic monitor and control; In this paper, relational database data on the status of identification and retrieval, the successful implementation of the large quantities of data in the sector automatic transfer between the processing and aggregation; the bulk of data processing workflow technology for security information management, better security information to enhance the management of hydropower plant efficiency and quality, greatly reducing the burden on management staff.
