2005 XQuery Industrial Status Investigation
DataDirect is a US XML-related tool product provider, which has released a XQuery use survey. It is said to be the first depth industrial survey on XQuery, let us see, this survey report:
1. XQuery's adoption rate
A survey of 550 software professionals shows that the adoption rate of XQuery is already soaring. For this question: "How long have you been using XQuery," Answer as follows:
52% said they have begun to use XQuery, and 33% said that they will start using XQuery in 2005. For a specification that has not become the final standard (XQuery is still in the stage of work, expected to be in 2006 Become a recommended standard), this ratio is really difficult.
2. Who is using XQuery?
About the use of XQuery's proportion, is represented by the following figure:
The results show that XQuery users have a wide range of developers, technical managers, senior managers and education sectors. Obviously, XQuery is no longer just the product of the academic ivory column, nor is it a patent of some "high people".
3. What kind of company is suitable for XQuery?
Is XQuery a business-level technology? Can it be applied to a smaller-scale company, a question in the investigation is "How big is your company?", As follows:
It can be seen that XQuery's user distribution is uniform, large, medium, and small companies are different.
4. What industry is using xQuery?
In order to understand the industry of using xQuery, investigate this question: "What industry is your industry?", The result is as follows:
The highest proportion is the IT consulting company, followed by software vendors, which showed XQuery's good prospects. Generally, for new technologies, IT's smell is the most sensitive, IT will play a good way, and software manufacturers Support also makes XQuery-related products and tools will be more and more, these tools are undoubtedly good for XQuery learning, use and promotion. The high proportion of the academic community also shows that XQuery has a good job in education and training. Out of these three industries, the most concentrated industry is the government, financial and telecommunications industries, and these three industries are just the most needed industry based on XML-based data integration programs. It is obvious that XQuery is considered to be these programs. Two choice.
5. Why choose XQuery?
So what is the power to promote XQuery change? Why do these users choose XQuery? For questions: "What is the main reason you use XQuery?" Answer as follows:
Simplify XML Data Access and Conversion. 43.1% of the investigators said that XQuery simplifies the access and conversion of XML data - currently existed in XML format, but there is no easy-to-use technology before XQuery, and the XML data is easy to use, and XQuery is easy Reading and understanding, and its syntax is not unfamiliar for database developers. Compact and concise grammar and programming style. 1/3 of the reason why they like the compact and simple grammar and programming style of XQuery - this point is unspected with a informal test result of DATADIRECT, tested, for querying and converting XML data sources Common use cases, the same function is completed, the code of the XQuery expression is 1/20 of the XSLT of 1/5 and low DOM mode. Unified various types of easy-quality data sources. The third reason is that XQuery can be used to deal with many data integration challenges. 24.5% of respondents believe that XQuery can across multiple heterogeneous data sources is the main reason they prefer. other. In "Other" reasons, XQuery follows W3C standards, lifting interoperability, and better application system performance. It is foreseeable that these advantages will be more pronounced when XQuery is determined by W3C as a recommendation criteria. 6 Conclusion
XQuery has such a high usage (73%) can't be parallel. In-depth analysis found that XQuery developers have a wide range of technical backgrounds, distributed in a variety of different sizes, and exist in many vertical industries, and their productivity provided by XQuery has a clear demand. Finally, the results also show that the XQuery standard has a wide range of supporters and a deep mass basis.
