XML Management System

XML Management System (shortened as XMLMS) is a system that allows queries and manipulation of XML data (similar to RDBMS querying and manipulating generic data). Current XMLMS can be divided into two categories: XML-Enabled databases and Native XML databases.

XML-Enabled databases

XML-Enabled databases, typically relational databases, provide extensions for transferring data between XML documents and themselves. Such systems are generally designed to store and retrieve data-centric XML documents.

Native XML databases

Native XML databases, on the other hand store XML documents in a collection and have powerful retrieval capabilities via XQuery. Because Native XML Databases don't need to map the data to and from a relational model they out perform XML-Enabled databases when inserting, updating and querying XML data. Native XML databases also allow XML data to be stored "as-is" without the need for a database schema. If however data must conform to a Schema, XML Schema is used as a validator.
