Comparison and synchronization of database schemas

This paper covers a problem of comparison of two relational database schemas, which may appear during work on a daily basis of both application developers and database administrators. In order to solve this problem, a set of mechanisms for application automating this task was suggested. Among those mechanisms there are transformation of database schemas to object model, data type mapping and differential DDL script generation.
