Comparativo de desempenho entre sistemas gerenciadores de banco de dados para armazenamento de dados XML em formato nativo

Abstract

Existing systems can be used on Desktop, WEB or Mobile, DBMS (Database Management System) to store your data and streamline your queries, as well as maintain data consistency. Thus, a correct choice of a DBMS is of paramount importance, so that the system can achieve its objectives of quality, integrity and reliability. Some types of data and documents are provided by health care sources and are stored in a database as efficiently and safely as possible. This is the case for XML (eXtensible Markup Language) files, which are data types not foreseen in the relational data model, and recently natively supported in the current DBMSs. In existing systems in the market there is an important need that is an issuance and receipt of electronic documents, they are in the fiscal area, health, public agencies, among others. Documents such as: NF-e (Electronic Invoice), TISS, CT-e (Electronic Transport). From this, storing, validating, and subsequently querying documents that are stored in their native format within a relational DBMS, requires medical care and planning when choosing the DBMS, so that the project requirements are best met. Using this scenario, this paper proposes a definition that can help in the evaluation of the DBMS. XML data type, that is, or document will be stored natively to the database.
