8) DBMS is meant to be for small organization and deal with small data. XML is intended rather to transport and pass data, RDBMS is for storing data. Dominate the persistence mechanism market, Standards, such as Structured Query Language (SQL) and JDBC well defined and accepted, Significant experience base of developers, Object-relational impedance mismatch can be a significant challenge, Mapping objects to relational databases takes time to learn, Native support for persisting XML data structures, For XML intensive applications it removes the need for marshalling between XML structures and the database structure, Standards (the XML equivalent of SQL, not yet in place for XML data access), Not well suited for transactional systems. As the number of users will be 30+, don't use Access, but Oracle, SQL Server, Sybase, … READ MORE.

The following summaries the general pros and cons of each mechanism: There is no one right answer on how to approach XML persistence. Some features of the site may not work correctly. Generally speaking, NXDs are not intended to replace existing databases but provide a tool for storage and operations on XML documents. Flat storage takes an XML document in a cell whereas shredded storage normalizes in into millions of parts. Since database systems form the backbone of essentially any information system, the integration of XML and database systems is a must.
