摘要
基于COM+的开放式分布PDM系统为客户端、Web服务器、应用服务器和数据库服务器4层结构模型。其应用服务器层已成为COM+的组件层。COM+组件中,安全策略组件用于PDM系统的安全机制,功能组件封装了系统的人员、流程、项目等基础管理功能。基础组件提供数据库驱动、文件操作等通用功能。标准接口组件提供各种标准接口。采用COM+技术,使PDM系统更加开放地在深层次与其他系统集成。
Open and distributed PDM system based on COM+ is composed of four layers architecture model of client server, web server, application server and database server. In this architecture, a web server and an application server was added into COM+ component layer. In COM+ components, Security components are used for the system security, all essential management functions such as employee, flow or project was encapsulated in function components. Foundation components provide some universal functions such as database driver and file operating. Standard interface components provide various standard interfaces for system input and output. For application of COM+ technology, PDM system is easier to integrate with other information systems in the deeper layer.
