Oracle SOA中的不同服务彼此相关?

我试图弄清楚 Oracle“分层架构模型”是如何工作的,但我对业务、数据和表示的作用以及它们之间的相互关系感到非常困惑。我看过很多图表显示它应该如何工作,但是一些现实世界的例子会有用吗?

例如,我猜测 Web 应用程序就是 Oracle 所说的“复合应用程序”,而这些 Web 应用程序是由 Oracle 所说的“演示服务”构建的。

I'm am trying to figure out how the Oracle "Layered Architecture Model" works, and I am very confused about what the business, data, and presentation do, and how they relate to each other. I have seen many diagrams showing how this should work, but some real world examples would be useful?

For example I am guessing that web applications are what Oracle calls "Composite applications" and that these web applications are built up of what Oracle calls "Presentation Services".

让我尝试尽我所知回答:

  1. OSB 是 BEA 的 ALSB 彻底改造的。其主要目的是 ESB 的工作。它位于表示层和应用程序的其余部分之间。它定义了应用程序的边界,并支持各个单元之间的协调。
  2. 包含业务逻辑的组件和各种子系统(想象一下组织中的不同部门)被称为复合。例如,这些组合可以在内部使用 BPEL 来表示业务逻辑,并使用 JCA 来获取它们本地的服务(数据库、ejb 等)。
  3. 这些Composite如果需要联系其管辖范围之外的服务(抱歉,想不出更好的词),他们需要联系 OSB。
  4. 服务中介的任何内部要求都由Mediator 来满足(不幸的是,这是 OESB 的大修

如您所见,这是 Oracle 的一种可悲的推销尝试包括他们最初的 ESB 解决方案以及他们从 BEA 购买的产品。让我告诉您,没有什么可以阻止您在 OSB 本身中连接内部服务(可能是 Oracle 的最终方向)

我相信您在重读并亲自实践后将能够找到更多信息。请求用您的发现更新您的问题。

Let me try to answer to the best of my knowledge:

  1. The OSB is BEA's ALSB overhauled. The main purpose of this is the job of ESB. It sits between your presentation layer and rest of the application. It defines the boundaries of your application, and supports mediation between various units.
  2. Your components and various subsystems that contain business logic (think of different departments in an organization) are termed Composites. For instance, these composites could internally use BPELs to represent business logic, and use JCA for reaching out services (database, ejbs, etc.,) local to them.
  3. These Composites, if need to reach out to services outside their jurisdiction (sorry, could not think of a better word,) they need to contact the OSB.
  4. Any internal requirements for a service mediation is satisfied by a Mediator (unfortunately, this is OESB overhauled)

As you can see, this is sort of a pathetic attempt by Oracle to sell both their original ESB solution, along with the products they bought from BEA. Let me tell you, nothing stops you from wiring your internal services in OSB itself (probably the ultimate direction of Oracle)

I am sure you will be able to find out more after rereading, and working hands on. Request to please update your question with your findings.
