Wang Xiang, a customs database expert, is optimistic about the data compression performance of DB2 9.

Wang Xiang is a database engineer at China Customs. He believes that:
"The choice of XML products is mainly because we have always been trusting and trusting XML products. After this introduction, we are full of confidence in DB2 9. After using DB2 9, we can smoothly overdo the relationship between the XML world and our previous world, which, more importantly, has changed our application development model. We use the unified data exchange mode and mybin format provided by DB2 9 to construct a unified data conversion structure for various heterogeneous raw data sources. After that, we can quickly define the interaction modes required by various users based on their needs. Through DB2 9, we will apply the compression technology, we can save and extract information more quickly. With the continuous expansion of database knowledge, compression technology can save more space for our storage and data to ensure that we can use less data to complete more work ."
