Resumen
The article focuses on object-oriented (OO) abstractions for distributed programming. There are as many definitions of the object-oriented programming paradigm as there is literature trying to define the paradigm. It is stated that OO programming is, first of all, about mapping a physical model of a problem domain into a program. An OO program is aimed at reflecting the structure of the application domain through a one-to-one correspondence between objects of the application domain and objects of the computational model. Since object orientation has become a respectable denomination in the industrial arena, there has been an important tendency to wrap built-in prototypes or products behind OO interfaces. This dressing is usually accompanied with a marketing campaign advertising the benefits of the new OO line of the system. This has been particularly true for various distributed programming toolkits. While an OO interface tends to make the functionality of the distributed toolkit easier to understand, it does not fundamentally improve its modularity extensibility or the reuse of its components, all concepts defining what OO programming is indeed about.
