Relationship Between XML and databases

, the smallest independent unit in the data is the pcdata element or attribute), and few or no mixed content. The sequence of appearance of the same level elements and pcdata is not important. A typical example is that XML documents include sales orders, flight schedules, restaurant menus, and so on. Data-centric documents are often used by machines. xml may be redundant-it is only a means of data transmission. For example, the following sales order document is data-centric: ABC Industries 123 M

The most important thing is that, like using SC and other tools, the effect of the INF file is immediate, and the file must be restarted after the Reg is imported.3. The inf file automatically adds a security sub-key for the Registry Key
