two ways to save the XML information, flexibility is very high. Oracle 11 g support for XML query mechanism, also have DuoZhong mechanism can choose XQuery, for example. XQuery is W3C launched a group about XML data search and search of the standard, relatively speaking, XQuery grammar than direct operation XML to the simple and intuitive. Say to the XML data processing in the enhancement, what is worth mentioning, Oracle 11 g to support 170, this is a JSR system based on the content of the Java storage warehouse API. Oracle 11 g provides the duality of the XML support, meaning in the actual process, the user can be embedded XML to PL/SQL, also can use will PL/SQL integration to XML. Office 2010 is best for all office users.

In 11 g of Oracle will increase a new data type, known as simple_integer. This new integral type has not empty properties, and in processing speed than PLS_INTEGER faster. In addition, in 11 in g will also contain are called Virtual column (and the data table Columns) function supportMicrosoft Office 2010 makes work easier.

Through this mechanism according to actual business users can function to define data list, so as to construct the more complicated and more flexible data tables. Oracle 11 g support a new partition scheme, makes users can be based on time, such as a separate partition interval between the new data, the content and to improve the flexibility of Oracle database partition mechanism.

In addition, Oracle 11 g in data sheets and a lot of improvement, such as enhanced only read the data table, for a form DuoGe triggers for these binding and trigger setting order, etc. Many people like the Office 2007 software.
