Database concepts and standards

These articles provide a basic background on concepts and standards for database management systems (DBMS). Many of these concepts apply to all forms of database management systems: relational (RDBMS), object (ODBMS), XML (XDBMS), and others as well as object-relational mapping and XML-mapping products.
