tight coupling to loose coupling, so that most analytical applications do not cause any changes in the data layer, whereas the MPP-based business intelligence system is able to perform high-performance analysis of detail data directly. This allows users to quickly develop data applications and then perform real-time analysis. 3Concluding remarksDT the arrival of the times, the value of data will be more and more people find, especially for large groups of enterprises, data from the production,

Elephant's mind inspires me a lot and it makes me more confident. Let me believe that as long as the learning will not learn things. 3, Time management GTD. Time management is a necessary skill for managers, through the use of tomatoes, this goal, mailbox, our time management capacity is also constantly strengthening. Time management so that we can

fast ... In our test of using business data, the serialization/deserialization performance of PROTOBUF is about three times times that of Json.NET, and the serialized volume is about One-second of JSON, which can improve the throughput performance of WEBAPI to a considerable degree.Disadvantages of ProtobufThe DTO layer must refer to Protobuf-net to add attributes, which in some way leads to code intrusion. Basically dtos belong to Poco, relying on third-party package of words always feel a bit
