  6. work estimation

    Work Breakdown Structure        Three Point Estimate       effort of Activity = ((Most probable Value * 4) + Pessimistic Value + Optimistic Value)/6   2. Lines of Code     Measure after the coding phase     Measure at the beginning of maintenance or conversion project     3. Delphi     several engineers individually produce estimates and converge on a consensus estimate at last. 3.1 A group of experts is each given the program's SPECs and estimation form 3.2 the experts discuss 3.3 anonymously list project tasks and  a size estimate 3.4 moderator collects the estimates and tabulates the results and return them to the experts 3.5 only each expert's personal estimate is identified; all others are anonymous. 3.6 experts discuss and review the tasks 3.7 continues from step 3.3 again utill converge to within an acceptable range     4. Function Point         Five aspects considered:        * External Inputs(EIs), Add&Update&Delete Records        * External External Outputs(EOs), Records Summary&Details        * External Inquiries(EQ),an input/output flow where input immediately generates the output, no logical data files modified        * Internal logical files(ILFs),maintained data model entity        * External Interface files(EIFs), maintained outside of the application       step1: determine the type of project: development project, enhancement project,installed application       step2: identify the Counting Boundary       step3: determine an unadjusted function point count       step4: Determine a value adjustment factor       step5: Calculate the adjusted function point count

  8. ESB 网关

    IBM ESB(Enterprise Service Bus)为SOA的服务提供者和消费者的交互提供中转, 连接,和分离。支持协议和消息格式的转换。   ESB一般位于隔离区(Demilitarized Zone), 进一步抵御来自企业区之外的恶意或未授权的访问。 “ESB 网关至少提供 ESB 与外部使用者/提供者之间的服务地址转换。在实践中,ESB 网关通常提供附加服务,例如安全性、消息转换和合作伙伴数据管理。” WebSphere DataPower 设备(例如 XI50 型)是作为主入口来公开的理想候选网关,用于所有的传入服务请求以及各自的响应。  主要是协议的转换。 同时与TAM(Tivoli Access Manager)协作提供安全性。这时候DataPower充当策略强制点。TAM充当策略决策点和标识提供者,并进行身份验证和授权决策。 与WSRR(WebSphere Services Registry and Repository)结合提供服务虚拟化。WSRR存储WSDL(端口地址,消息格式)
