摘要: The Common Object Request Broker Architecture (CORBA) defined bythe Object Management Group (OMG) has become an emerging industry standardof distributed objects technology. It provides the interconnection busbetween distributed objects and a mechanism to develop platform- and language-independent distributed applications. The Object Query Service (OQS) proposed by OMG defines a very general facility for querying collections of objects. Through OQS, clients can use a simple interface to find objects whoseattributes meet the search criteria specified by a query. The query can be formulated using either SQL query or ODMG's OQL. In thesis, we design and implement the Object Query Service based onCORBA. Our Query Service acts as a middleware to both relational databases and object-oriented databases. Clients are able to issue either SQL query or OQL query, and our OQS will retrieve and translate the results into CORBA objects that have both platform- and language-independent properties. TheseCORBA objects can be passed anywhere on the ORB and they can be shared by different application objects.
