XML latest information

Many media are talking about the status of XML and its prospects. The full name of XML is eXtensibleMarkupLanguage.

Its function as a group language has gone beyond SGML and is usually translated into an extensible group language.

E-commerce in 2003

At present, the scale of e-commerce in Western countries is increasing. In the United States, the establishment rate of e-commerce (EC) is 33%, and the total transaction on the Internet has reached 9%. In Japan, it is estimated that it will reach 11.3% by 2003, which is 7 times stronger than in 2000. Moreover, the EC market in the Asia Pacific region will reach 1.6 trillion U.S. dollars by 2004. Facts indicate that the scale of such transactions will be conducted on the Internet. This change will have a negative impact on intelligence collection and e-mail, but it will have a positive impact on the EC sector and corporate PR.

Popularization of XML

Recently, in the bookstore's bookshelf about XML, in the past, books such as XML introductory or XML based commentary have all been replaced by technical and practical books on how to use XML. The EC is the most cited example in the book. In the business work that is usually done, in order to achieve the first step of the work, as long as the use of XML, it is simple and convenient, the cost will be reduced, in particular, think of the business work combined with the Internet, in order to achieve its business, what means, In terms of approach and IT, it is believed that the goal is XML. If you use XML, you can do your work with great joy.

XML comes from SGML, HTML ideas. The SGML of ISO 8879 in 1986 was difficult to popularize at that time and it could not be popularized so far. The reason is that the grammar is very difficult, and it has certain technical difficulties and can only be applied in special fields.

The period when XML was officially recommended by W3D in the XML 1.0 grammar was February 1998. Just over three years ago, it has been popularized to the present day. It shows that in the Web that represents HTML, the form of presentation as document data is excellent, and it is cheap and simple. Recently, XHTML has appeared again.

Computer understandable language

Why do you want to promote XML today? This is because XML comes from SGML. XML is a meta language, which is the language of the production language. It can be described in its language. PDF, HTML, and SGML are all the same. They are not printed media such as paper. They are electronic documents that have a very good structure as an electronic data exchange in the Internet era.

On the other hand, in e-commerce, XML has been widely used. One of the reasons for this is the exchange of information and the accuracy of the data. The second reason is that because of its excellent programmability, XML will undoubtedly become the backbone of Web services.

The biggest feature of XML is the verification of the file structure. The structure, content and format of the file are completely removed. To put it another way, the software of the computer can understand the meaning of the file, which is beyond the doubt of HTML.

In the same Web, as a file, a page written in HTML and a page written in XML are the same as seen in the eye and can also be used for information transfer. However, once you let the computer look, HTML is fixed because of the markup. How many items are there and what kind of data is not clear? If you change to XML, you can make it meaningful on the name of the mark. Specifically, you can find the table. How much is this item in the price, quantity geometry.

When I was planning on exchanging intelligence knowledge, I used to clearly write on paper to exchange with people in the same industry. Now I can use computers to exchange. If it is HTML, the other party's computer cannot understand it. If it is XML, people can understand each other. The computers can also understand and handle them. Therefore, XML is favored and promoted in the field of intelligence knowledge management.

EC shifts from EDI to XML
EC on the Internet, originally using EDI (Electronic Data Interchange), has a tendency to switch to XML. EDI has a variety of specifications. Because data exchange is required between companies and enterprises, the format of data and the outline of its contents must be determined. In the past, although it was not too many, it was decided by the other party to make such transactions. However, in today's era, various companies not only trade in the same industry, but also trade across industries. In other words, the transactions that originally belonged to their own consular districts were continuously joined by different industries, and there was no longer a framework between the industry and the industry.
However, in the past, the use of EDI to exchange data must be carried out in accordance with prescribed procedures. Once the counterparty is changed, new regulations must be made. According to the rapid development of the Internet, the methods and modes of business work have also changed. According to the previous EDI format, the phenomenon of inability to supplement often occurs, making it very cumbersome to change. The reason is that there is no expansion, which is the shortcoming of EDI.

In this case, XML is used instead, first to determine the minimum required, and then to add the corresponding function, that is, to add words. In fact, to describe the characteristics of XML, there are two points. One is self-explanatory, that is, one can explain the content of his own file, and the computer that accepts it can handle it according to the content of the description. The second is that scalability is very simple. In order to unify the standardization of the industry as a whole, it is of great significance to accelerate the development of e-commerce in the future because the data and documents that are manipulated cannot be realized without expansion. Considering that XML must be noticeable.

You can extract the necessary parts

In the past, what was the difference between using EDI and XML? For example, if a new product is produced, it is necessary to give its product introduction information to the customer, including various items such as product name, standard price, supply price, quantity, and the like. All of them are accepted by EDI and transferred to the enterprise system for processing.

However, when the manufacturer sends the information to the sales store, the receiving store does not need all of its information. It only needs the product name, code, standard price, and production period to satisfy the main data for sales. However, promotion departments such as planning and publicity have to produce catalogues, and also require photographs, introductions, and characteristics of products. It is not easy to take so many information in one basket and take over it from the company’s intelligence system. .

If there is a large whole and its parts are not independent XML, the information received from the other party’s company will only put the necessary parts into the workflow system of the company, which is much more convenient. For the columns needed for the promotion, such as the photo, name, price, use, etc. of the product, with a few conditions, the electronic data can be sent to the printing company and completed automatically. The future application of this form will wait and see.

Extend the use of XML

Speaking of XML, there are many types, and the basics are XML 1.0 and grammar. This was established in February 1998. In order to achieve a variety of performances, the key is grammar, but this alone is not enough, there are other various specifications.
