Embodiment 1
[0028] A method for designing a cascading medical condition inquiry program is characterized in that the data source of the medical condition inquiry is in the form of a database, and each layer of questions has its corresponding level relationship. Except for the last level of questions, all other levels of questions have the ID of the next level of the current question, thus creating an association relationship with the previous question. After the user enters the medical condition, the program will cache and retrieve the medical condition question, and if there is no medical condition history, it will search the database for the first-level question reply data. Specific steps are as follows:
[0029] (1) The user enters his or her condition, such as keywords such as headache;
[0030] (2) The program will search in the cache. If it exists, it will directly return the field string in the cache. If it does not exist, it will access the database to find the next-level questio...
Embodiment 2
[0033] This embodiment is further optimized on the basis of the above-mentioned embodiment 1. Further, in order to better realize the present invention, in the step 2), the cache server uses redis to traverse all existing key values in redis, and then Perform fuzzy matching with all key values in redis according to keywords. If the match is successful, use the current key to retrieve the value. If it does not exist, the database is looked up.
Embodiment 3
[0035] This embodiment is further optimized on the basis of the above-mentioned embodiment 2. Further, in order to better realize the present invention, in the above-mentioned cascading condition inquiry program design method, the value values in redis are all objects , and is the next question data object List.
