RSS 1.0 is the only version that was developed using the W3C RDF (Resource Description Framework) standard.The idea behind RDF was to help create a Semantic Web.create table test( rc1 int, rc2 char(4), info xml) DB20000I The SQL command completed successfully.describe table test Data type Column Column name schema Data type name Length Scale Nulls ------------------------------- --------- ------------------- ---------- ----- ------ RC1 SYSIBM INTEGER 4 0 Yes RC2 SYSIBM CHARACTER 4 0 Yes INFO SYSIBM XML 0 0 Yes 3 record(s) selected.
In such cases DB2 automatically generates and maintains a “regions” index to provide an efficient means of tracking the XML tree.
Without RSS, users will have to check your site daily for new updates. With an RSS feed (RSS is often called a News feed or RSS feed) they can check your site faster using an RSS aggregator (a site or program that gathers and sorts out RSS feeds).
Since RSS data is small and fast-loading, it can easily be used with services like cell phones or PDA's.
The first line in the document - the XML declaration - defines the XML version and the character encoding used in the document. However, this can be very time consuming, especially for pages with lot of updates.
In this case the document conforms to the 1.0 specification of XML and uses the UTF-8 character set. An alternative is to use a third-party automated RSS. RSS readers are available for many different devices and OS. Some work as web services, and some are limited to windows (or Mac, PDA or UNIX): Tip: Most browsers have a built-in RSS Reader.
The relational columns/data are stored in traditional row structures while the XML data is stored in hierarchical structures.
