Relational Database Articles
This section is not fleshed out. In the meantime, there are many good books on relational database management system (RDBMS) products. We suggest you investigate the books that are available.
Also check out the database concepts and standards articles. Many of these database 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.
