A detailed description of the advantages of the DB2 9 database

This article mainly introduces the detailed analysis of the advantages of the DB2 9 database. We all know that XML is a flexible language to use. Users can tag their own tags to define their data types. You can define the principle or attribute name in these tags.

In this way, the XML file can be easily read by another user who has no knowledge of the system.

XML is a flexible language. Users can tag their own tags to define their data types. In these tags, users can define their own principles or attribute names. In this way, as long as an XML file is obtained, another user who has no knowledge of this system can easily read the data.

When different users exchange data, as long as they follow the XML standard, each application can write an XML interpreter for the data types they use, the data in the XML file is easily converted into the data type used by the user, so that data can be quickly exchanged between different applications.

However, as a database that stores data, Relational Tables in the past cannot meet this new requirement. You still need to spend a lot of time converting XML data to the relational type and then entering the database, or writing complicated queries as needed to read the data. This method not only adds difficulty but also reduces efficiency. The original XML file will be re-parsed to each table. This process is quite resource-consuming for systems with complicated or large data volumes.

Compared with other database management systems, DB2 9 has made significant innovations. In fact, DB2 9's support for XML is not only reflected in XML data, but also can be used to solve some problems that are difficult to solve Using relational models. DB2 9's support for XML is not negligible compared with the classic relational data model.

The above content is a detailed analysis of the advantages of the DB2 9 database. I hope it will help you in this regard.
