we propose a model developed to have inherent capabilities for auto-adaptation between classes and instances. Our two main objectives are: to allow objects to evolve their structures dynamically, with all necessary impacts on the database schema; to allow, similarly, the creation and display of different plans for evolving the design, like ways of schema evolution, giving in this way a simulation tool for database design and maintenance. Artificial Life and Genetic Algorithms inspired the idea of objects evolving and adapting to their environment. A model evolution is then considered in an auto-adaptive loop between classes and instances. Change is two-way: that coming down from class to object instantiates in development processes; that coming up from object to class in emergence processes which concern evolved instances which become not conform to any existing class.
