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: The present disclosure provides a picture book sharing method as well as an apparatus and a system using the same. The method includes: receiving, through a server node, an upload request for data of the picture book from a first client; storing the pictures and the audios in the data of the picture book to a file storage server, and obtaining storage addresses of the pictures and the audios; creating an index for the storage addresses and the texts in the data of the picture book, and storing the index and the texts in the data of the picture book to a search server; and searching for the texts corresponding to the picture book requested by a search request from a second client, obtaining the pictures and the audios corresponding to the texts according to the index, and transmitting the obtained texts, pictures and audios to the second client.

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.

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.
