RESUMEN

Matering software development is a chanllege.Up tp now, all the propositions done have come out with new languages.In this paper, we present a development framework in which different approaches can be supported and the program is a component.Within the enviroment operators enable the incremental construction and modification of programs,separating the use of design concepts from the technical details of how they are captured in the programming language. They also offer flexibility since it is possible to define a library of operators capturing alternative definitions of particular concepts and strategies. the focus of this paper is to show object-orientation is introduced without a new language. A set of development operators enabling object-oriented software development is defined and then used in a simple case study.
