Furthermore, when updating the content data of courseware slices on the courseware cache server, the update strategy adopted is: only update the content data that has changed due to secondary editing, and do not update the data that has not changed, thereby reducing The amount of data processed improves the update efficiency. For example, the content data of a courseware slice includes: knowledge point introduction and knowledge point test, if only the test type of the knowledge point test is edited twice, only the test type will be updated when the content data of the courseware slice is updated , without updating the data corresponding to the knowledge point introduction corresponding to the courseware slice.

S103. The original courseware server updates the content data of the corresponding original courseware slice locally stored by the original courseware server according to the ID of the courseware slice whose content data has been updated.

In this embodiment, when updating the content data on the original courseware server, the above strategy of updating on the cache server is also adopted to reduce the amount of data processing and improve the update efficiency.

Specifically, when updating, the original courseware server uploads the compressed updated courseware slices from the cache server, and replaces the stored original courseware slices, so as to complete the update of the courseware slices. In addition to creating a new courseware slice, if it is a courseware slice generated by other modification operations, the original courseware slice can be replaced by matching the ID of the courseware slice. If you are creating a new courseware slice, you can directly allocate a storage space on the original courseware server for storage.

It should be noted that during the above update, the courseware configuration information may also be updated according to the courseware slice ID corresponding to the updated courseware slice.
