XSD DATA TYPES
XML Database
XML database is a data persistence software system used for storing the huge amount of information in XML format. It provides a secure place to store XML documents.
You can query your stored data by using XQuery, export and serialize into desired format. XML databases are usually associated with document-oriented databases.
Types of XML databases
There are two types of XML databases.
- XML-enabled database
- Native XML database (NXD)
XML-enable Database
XML-enable database works just like a relational database. It is like an extension provided for the conversion of XML documents. In this database, data is stored in table, in the form of rows and columns.
Native XML Database
Native XML database is used to store large amount of data. Instead of table format, Native XML database is based on container format. You can query data by XPath expressions.
Native XML database is preferred over XML-enable database because it is highly capable to store, maintain and query XML documents.
Let's take an example of XML database:
<?xml verson="1.0"> <contant-info> <contact1> <name>rama</name> <company>IBM</company> <phone>9100400110</phone> </contact1> <contact2> <name>Krishna</name> <company>tcs</company> <phone>9400511220</phone> </contac2> </contact-info> |
