Relative to structured data (the data is stored in the database, it is possible to use two-dimensional table structure to express the implementation data logically, the data that is not convenient to use the database two-dimensional logical table to represent is called unstructured data, including all format Office documents, text, picture, XML, HTML, various kinds of reports, images and audio/ Video information and so on. An unstructured database is a database with a variable field length and a record of each field that can be made up of repeatable or repeatable child fields, not only to handle structured data (such as numbers, symbols, etc.), but also ...
Microxml is one of the results of these discussions. Microxml is a backward-compatible, simplified version of XML, where the prominence of some of the participants and the timing of the microxml appear. John Cowan has developed the Microxml parser in Java™ and other related tools. This article describes the technical differences between Microxml and its XML 1.x and related standards. XML is a highly successful technology, but it is not without flaws. After great success ...
In 2017, the double eleven refreshed the record again. The transaction created a peak of 325,000 pens/second and a peak payment of 256,000 pens/second.
