[0004] However, in the process of realizing the present invention, the inventor found that in the online loading mode of the existing client / server (Client / Server, C / S) system, the client and the server end are loaded through a constant connection, The loading time of the server depends on the normal operation of the system client, and there is an inevitable hidden danger of loading errors
Especially when the amount of data is large and the loading time is long, if the client of the system encounters various unexpected situations such as power failure, crash, and network disconnection, the data loading process of the server will be affected or even destroyed.
The final result ranges from data loading failure to severe damage to the original data in the system

Embodiment Construction
[0021] In the embodiment of the present invention, during the data loading process of the C / S system, the client uploads data loading tasks in batches, and after receiving the data loading tasks, the server disconnects from the client and starts the loading service to execute the received data. For loading tasks, the data loading that originally took a long time to process is handed over to a stable server for processing, reducing the hidden danger of data loading failure due to unstable factors on the client side. Wherein, the above-mentioned C / S system refers to a system supporting the C / S mode. The C / S mode is a software system architecture, through which the advantages of the hardware environment at both ends can be fully utilized, and tasks can be reasonably allocated to the Client and Server to achieve, reducing the communication overhead of the system.
[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present i...

The invention discloses a data processing method, a server and a data processing system. The method is used in a customer / server (C / S) system, comprising the following steps: a customer terminal uploads a data loading task to the server in batches by establishing the uploading service connection with the server, the uploading service connection between the server and the customer terminal is disconnected after the server finishes receiving the data loading task uploaded in batches, and loading service is activated to implement the received data loading task. By adopting the invention, the customer terminal sends data needed to be loaded in package and batches to the server, the connection between the server and the customer terminal is disconnected after the server finishes receiving, new loading service is activated to independently complete data loading, therefore, the server is not affected by the unstable factor of the customer terminal when the server loads data, thus improving the stability of data loading.
Description
technical field [0001] The invention relates to the field of data processing, in particular to a data processing method, server and data processing system. Background technique [0002] ETL: (Extraction-Transformation-Loading, the Chinese name is data extraction, conversion and loading) refers to extracting data from distributed and heterogeneous data sources, such as relational data, flat data files, etc., to a temporary intermediate layer for cleaning and conversion , integration, and finally loaded into the data warehouse or data mart, which becomes the basis of online analytical processing and data mining. [0003] At present, common ETL tools usually use the client to establish a connection with the server, and the client uses the communication after the connection to execute the loading command on the server. And use the progress algorithm to realize the loading progress display of the client. [0004] However, in the process of realizing the present invention, the i...
