An approach to relational database schema integration

The main goal of the paper is to give a formalization of the relational database schema integration process, as a part of a database schema design. We briefly describe the form type concept and the module schema design, which are related to the integration process. Database schema of the information system is obtained by progressive pairwise integration of so called database module schemes, that are usually built by different designers. An integration process is preceded by checking of database module schemes onto mutual consistency.
