From last ten years or more HTML 4 has been widely used but with the growing needs of the web, website builders are now requiring new and advanced techniques that can assure enhanced functionality, most web developers find problems due to the HTML 4 language and browsers.In order to provide more flexibility and interoperability, and also allow more interactive and exciting websites and applications, HTML 5 will be introduceing a wide range of features including form controls, APIs, multimedia, structure, and semantics. Sounds exciting Huh! Sure indeed…

HTML 5 started way back in 2004, development in this area is being carried out in a joint effort between the W3C HTML WG and the WHATWG. Many more participants in this W3C initiative include representatives from the four major browser vendors Apple, Mozilla, Opera, and Microsoft. Also some more organizations and individuals of diverse interests and expertise.

If you research you will find that the specification is still under progress and quite a long way from completion. We may expect a lot more that gets introduced or included in this. But it certainly is exciting to see web changing so much and so well.

As happens with evolving standards, support for XQuery is making its way into mainstream products. IBM’s DB2 version 9, for example, implements XQuery as part of its hybrid server. And Oracle gives database developers a choice of embedding XML inside SQL queries or employing the XQuery standard. Such developments represent an important change in the potential value of XML data.

The W3C’s Xquery 1.0 moved to Proposed Recommendation status in November, bringing the prospect of a SQL-like approach to XML data querying one step closer to official sanction. Reported on NetworkComputing today.

XQuery essentially enables relational vendors to bring XML processing deeper into their database engines. The relational DBMS can then build XML indexes for optimizers to use, so the system can perform queries against XML data with the same efficiency as SQL. XQuery is also important for tiered architectures; database and middleware vendors can employ XQuery to access XML or SQL data from multiple, heterogeneous sources.

But XQuery is immature; it offers read-only access to XML data, though updating and other functions will be added later. And XQuery is not at all ready to support analytics and BI (business intelligence), unlike SQL.
