Abstract: A data transmission method is performed in a storage system. The storage system includes a load balancing device and a data storage server cluster. The data uploaded by a terminal is stored in one data storage server of the data storage server cluster, which can avoid single point of failure.

Abstract: The present disclosure relates to an object trajectory tracking and displaying method, comprising the following steps of: creating a mapping relationship database of image features and WIFI information for objects in a distributed search server, where each WIFI information includes position information; receiving a trajectory query request for a monitored object; searching the mapping relationship database of image features and WIFI information for objects according to an image feature of the monitored object to produce a WIFI information set, and producing a corresponding position information set based on the WIFI information set; and generating real-time trajectory information of the monitored object based on the position information set. The object trajectory tracking and displaying method and system of the present disclosure make the position of the sampling data points more accurate and improve the accuracy of trajectory querying.

Abstract: A data processing system comprises a loading server and a query server. The loading server is configured to extract updated data from at least two table databases and insert the updated data into the query server. The query server is configured to create an inverted index for querying the updated data, and the inverted index is indexed to an index table of the query server.
