Oracle SOA中的不同服务如何相互关联? [英] How do the different services in Oracle SOA relate to each other?

问题描述

我正在尝试弄清楚Oracle分层体系结构模型"是如何工作的，并且我对业务，数据和表示的功能以及它们之间的相互关系非常困惑.我已经看到了很多图表，显示了它应该如何工作，但是一些现实世界中的示例会有用吗?

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?

例如，我猜测Web应用程序是Oracle所谓的复合应用程序"，而这些Web应用程序是由Oracle所谓的"Presentation Services"构建的.

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".

推荐答案

让我尝试尽我所能:

1. OSB是BEA的ALSB大修.其主要目的是ESB的工作.它位于您的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中介.
2. 将包含业务逻辑(例如组织中不同部门)的组件和各种子系统称为Composite.例如，这些组合可以在内部使用BPEL表示业务逻辑，并使用JCA来访问它们本地的服务(数据库，ejb等).
3. 如果这些Composite需要联系其管辖范围之外的服务(对不起，想不出更好的说法，)，则需要与OSB联系.
4. Mediator可以满足任何服务调解的内部要求(不幸的是，已对OESB进行了大修)

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)

您可以看到，这是Oracle出售原始ESB解决方案以及从BEA购买的产品的一种可悲的尝试.让我告诉你，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)

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)

我确信您可以在重新阅读并继续工作后找到更多信息.要求用您的发现更新您的问题.
