SOA原理与集成实例1幻灯片.pptVIP

定义服务 映射已有功能服务：如查询存款记录、查询贷款记录和担保。 新建流程服务：如贷款流程、评估信用等级。 新建人工服务：如审批。 新建业务规则服务：如计算信用等级。 新建功能服务：如确认购车价格。 服务的组成 服务分为Interface和Implementation两个部份。 其中Implementation部份可以基于新开发的应用程序；已存在的应用程序；原有服务的组合。 使用SOA构建企业应用 SOA的治理模型 Web服务的监控 1.把监控代理安装在布署有Web Service的应用服务器上。 2.设置监控条件 3.监控代理侦听到服务性能信息违反了预先设定的条件后，发出报警事件。 4.监控服务器接收事件，进行处理，显示在管理控制台上。 CONFIDENTIAL - All Rights Reserved * 目录 从技术角度理解SOA 从业务角度理解SOA SOA项目的开发流程 SOA集成实例 * 集成步骤 Existing Systems Analysis Data Modeling Service Design Service Implementation Integration Design Security Design Governance Process * Existing Systems Analysis 1.
