Advantages of Distributed Object Architecture
• •It allows the system designer to delay decisions on where and how services should be provided It is a very open system architecture that allows new resources to be added to it as required
• The system is flexible and scaleable
• It is possible to reconfigure the system dynamically with objects migrating across the network as required
Weakness of Distributed Object Architecture
• Tightly coupled
– Both ends of each distributed computing link had to agree on the details of the API.A code change to a COM object,for example,required corresponding changes to the code accessing that object.
• Proprietary
– Microsoft controlled DCOM
– Implementing a CORBA architecture typically necessitated the decision to work with a single vendor's implementation of the specification
SOA -- Evolution vs.Revolution
• SOA is developed upon the weaknesses of distribute object computing technique.
– Standard-based
• Reliance upon universally accepted standards provides broad interoperability among different vendors’ solutions
– loosely couples
• Separates the participants in distributed computing interactions so that modifying the interface of one participant in the exchange does not break the other.
Summary
• SOA enables dynamic collaboration among loosely coupled,reusable software components through standard Internet protocols.
•
• SOA is driven by both business and technology needs for open collaboration,cost saving and flexibility to dynamic changes.
•
• SOA is developed from other software techniques including distributed object computing,component-based software engineering,and enterprise application integration.

的优势,分布式对象结构
• •它允许系统设计者拖延的决定在何处和如何服务,应提供,这是一个非常开放的系统架构,允许新的资源,要添加到它的要求,
•该系统是灵活的和可扩展
•是有可能重新设定系统的动态与物体迁移到整个网络的要求
弱点,分布式对象结构
•紧耦合
-两边的每一个分布式计算的联系已同意就有关细节的空气污染指数.代码变更为COM对象,例如,需要相应的改动代码访问那个对象.
•专有
-微软控制的D COM
-实施C ORBA的架构,通常需要决定的工作与单一供应商的实施规范
国家海洋局-演化与革命
• SOA是发达后的弱点,分发对象计算技术.
-基于标准
•依赖普遍接受的标准,提供了广泛的互操作性不同供应商的解决方案
-松散的夫妇
•政企分开,与会者在分布式计算中的相互作用,以便修改界面的一位与会者在交流不打破其他.
摘要
•国家海洋局,使动态之间的协作,松耦合,可重用的软件组件通过标准的互联网协议.
•
• SOA是驱动双方的业务和技术的需求,开放协作,节省成本和灵活性的动态变化.
•
• SOA是从其他发达国家的软件技术,包括分布式对象计算,基于构件的软件工程和企业应用集成
