INTEGRA O DE ESQUEMAS RELACIONAIS E XML COM REALIZA O DE CONSULTAS NA BASE DE DADOS INTEGRADA

Database Management System (DBMS) is usually done according to the business rules of the represented reality. Organizations that have the same business do not always have the same data structures, because they have been designed by different people and to meet different requirements. Currently, the identification of the correspondence between relational schemas is done manually in most cases and has been a research subject in the Database area. This process is essential to enable the integration between schemes created independently and from different databases, since the problem of integration is the transport of data stored in one scheme to another. After identifying the correspondents attributes between different schemas using many techniques, it is necessary to integrate these information to facilitate the data search in both schemes. Even with the integration and relationship approach created, the correlation between schemes is semiautomatic because attributes can be connected without having real similarity.
