Abstract
The query synchronization is one of main issues of schema evolution: when a schema evolves the existing queries could stop working and it becomes necessary to redefine them over the new schema. In this paper, according to the recently recognized importance of advanced query formulation inter- faces, the basic ideas and components underlying an inter- active model of tool for supporting query synchronization are outlined.
