Example three, the server 20 further includes: a source data update monitoring module (not shown in the figure); the method and the device are used for monitoring whether the data in the source database is updated or not, if the data in the source database is updated, the data in the source database is updated to the download database, or the data in the source database is updated to the download database when the source database is idle.
In example three, the source data update monitoring module may be specifically configured to: and acquiring a second preset updating data time table of the source database, monitoring whether the second preset updating data time table is updated or not, and if the second preset updating data time table is updated, updating the data in the source database to the downloading database, or updating the data in the source database to the downloading database when the source database is idle.
Optionally, the data in the source database refers to full data or newly added data; the full data refers to the full data in the source database, namely all data; newly added data is data different from the data in the downloaded database; those skilled in the art can select whether the data in the source database refers to the full amount of data or the new amount of data according to actual needs, which is not limited herein.
Specifically, if the data in the source database is the full data, updating the data in the source database to the download database means updating the full data in the source database to the download database, that is, updating all the data in the download database; if the data in the source database is the new data, updating the data in the source database to the download database means updating the new data in the source database to the download database, that is, updating the new data that is not included in the download database, and keeping the other data unchanged.
It should be understood that, in the above three examples, the data in the source database is updated to the download database automatically, and of course, a person skilled in the art may also update the data in the source database to the download database manually, which is not limited herein.
In an optional embodiment of the present invention, the server 20 further includes: a data update module (not shown in the figure); the system comprises a downloading database, a first preset updating data time table, a second preset updating data time table and a third preset updating data time table, wherein the downloading database is not updated if the time of the last updating data in the first preset updating data time table is the same as the time of the last updating data in the second preset updating data time table; and if the time for updating the data in the first preset data updating time table is different from the time for updating the data in the second preset data updating time table, updating the data in the source database to the downloading database.

The third and fourth ways of updating the data in the source database to the download database may specifically include: acquiring a second preset updating data time table of the source database; monitoring whether the second preset updating data time table is updated or not; and if the second preset data updating schedule is updated, updating the data in the source database to the downloading database, or updating the data in the source database to the downloading database when the source database is idle.
In a fifth way of updating the data in the source database to the download database, after the time of updating the data last in the first preset update data schedule is different from the time of updating the data last in the second preset update data schedule, the method further includes: respectively taking the time of the last updated data in the first preset updated data time table and the time of the last updated data in the second preset updated data time table as the starting time and the ending time, and extracting the data in the source database as the newly added data; and updating the newly added data to the download database.
It should be understood that, the five ways of updating the data in the source database to the download database are to automatically update the data in the source database to the download database, and of course, those skilled in the art may also manually update the data in the source database to the download database, which is not limited herein.
In the embodiment of the present invention, steps S101 to S105 are not limited to the sequence of steps, so that the step of updating the data in the source database to the download database may be completed at any time before step S105, or may be completed after the FTP server in step S105 verifies the data, and a person skilled in the art may select the step according to actual needs, without limitation.
Preferably, step S103 is implemented by two parallel threads, specifically a first thread and a second thread; the first thread is used for verifying whether a target database of the client has the authority of updating data from the download database or not according to the user identity verification information; the second thread is used for verifying whether the data in the target database of the client needs to be updated or not according to the data updating verification information; wherein the data update verification information includes a third preset update data schedule.
Optionally, step S103 further includes: when the first thread and the second thread pass the verification, the FTP server sends verification request information to the client to verify whether the data updating request information of the client is changed; when any one of the first thread and the second thread fails to verify, the verification of the other thread is stopped at the same time, and the data in the target database of the client is refused to be updated.
In an optional embodiment, the second thread specifically includes: acquiring a first preset updating data time table of a downloading database; acquiring a third preset updating data time table according to the data updating verification information; comparing the first preset update data schedule with the third preset update data schedule; if the time of the last updated data in the first preset updated data time table is the same as the time of the last updated data in the third preset updated data time table, refusing to update the client; and if the time for updating the data in the first preset data updating time table is different from the time for updating the data in the third preset data updating time table, determining that the data in the target database needs to be updated.
In another optional embodiment, the second thread specifically includes: acquiring a second preset updating data time table of the source database; acquiring a third preset updating data time table according to the data updating verification information; comparing the second preset update data schedule with the third preset update data schedule; if the time for updating the data in the second preset data updating time table is the same as the time for updating the data in the third preset data updating time table, refusing to update the data in the target database; and if the time for updating the data in the second preset data updating time table is different from the time for updating the data in the third preset data updating time table, determining that the data in the target database needs to be updated.
The method adopts two parallel threads to simultaneously verify whether the client has the authority of updating data from the download database and whether the data in the target database of the client needs to be updated according to the data updating verification information, thereby shortening the time spent in the verification process and improving the verification efficiency.
Optionally, after the verification by the FTP server is passed, updating the data in the updated download database to the target database, including: respectively taking the time of the last updated data in the first preset updated data time table and the time of the last updated data in the third preset updated data time table as the starting time and the ending time, and extracting the data in the download database as the newly added data; and updating the newly added data to the target database.
