Finally

The author designs to continue working on the book adding to it new problems and algorythms. New chapters will be added which are dedicated to DDL — Data Definition Language, to normalization of relations and to the basics of optimization of queries. However, these plans can be realized only in case of readers’ favorable attitude towards the book. That is why the author would like to know your opinion.
