[13.1] I USE DCE PRODUCTS; WHY SHOULD I USE CORBA AND NOT DCE? NEW!

The OSF developed a Distributed Computing Environment (DCE) long before CORBA was developed. There is an existing installed based of DCE distributed systems. However, the number of DCE vendors, and the number of platforms supported by DCE is small compared to CORBA.

The CORBA and DCE environments can interoperate with the correct kind of gateway. DCE is recognized by the OMG as an important environment and has standardized the DCE Environment Specific Interoperability Protocol (DCE-ESIOP).

[13.2] MUST I CHOOSE BETWEEN DCE AND CORBA? NEW!

[Recently created (3/1999). Click here to go to the next FAQ in the “chain” of recent changes]

No. Distributed applications can be developed using both CORBA and DCE. For example, a client application might be developed to access a set of DCE objects, and DCE objects might in turn access CORBA objects. The OMG has defined a DCE<->CORBA interworking specification which standardizes this sort of bridging.

[13.3] IS CORBA MORE MATURE THAN DCE? NEW!

[Recently created (3/1999). Click here to go to the next FAQ in the “chain” of recent changes]

No. DCE was developed before CORBA. This gives DCE a longer track record of successful and unsuccessful system installations.

A major distinction between DCE and CORBA, however, is that CORBA was developed with the benefit of object-oriented concepts.

Another distinction between DCE and CORBA is the breadth of the standard. CORBA is a broader specification, and aims to standardize interface definitions and common services in an object-oriented manner.
