隨著分散式系統及物件導向技術的發展，以物件為基礎的分散式架構也受
到高度重視。因此，OMG(Object Management Group)在1990 年就制定了
一個分散式物件溝通的標準-CORBA(Common Object Reguest Broker
Architec ture)，這是目前最受業界支持的分散式物件的標準。
在本篇論文中，我們將介紹整合OODB(Object-Oriented Database)及
CORBA的兩種架構-Wrapper以及Adapter，並且設計一個"CORBA/OODB
Wrapper Library"來結合OODB 以及ObjectStore。藉由我們所設計的程式
庫，程式設計師可以很容易就寫出一個整合ObjectStore以及CORBA的應用
程式，而客戶端(Client)透過支援Java的瀏覽器就可以存取到存在
ObjectStore中的物件，進而達到分散式儲存及計算的目的。

With the development of distributed systems and object oriented
technology, the object-based distributed architecture has been
conspicuous gradually. Therefore, the OMG (Object Management
Group) specifies a standard, known as CORBA(Common ObjectRequest
Broker Architecture), for distributed object exchanging. In this
thesis, we introduce two approaches, wrapper and adapter, to
integrate OODB with CORBA, and discuss the difference of them.
Then we implement libraries to realize the architecture "CORBA/
OODB Wrapper" for combining ObjectStore with CORBA. A programmer
can design the application that supports ObjectStore and CORBA
with facility by using the libraries we provided, and the client
can easily use a java-enabled Web browser to access objects
stored in ObjectStore. By this way, we can achieve a certain
degree of distributed object storage and mobile computing.
