Abstract: A self-learning, self-healing database-management system determines that erroneous input, such as an improper SQL query, has caused a critical database condition. The system parses each input statement into a set of tokens, and then translates each set into lines of a failure script. The script is consolidated by cross-referencing each line to infer relationships between input statements. The system then searches historical database logs for previously entered, error-free input similar to the erroneous input. A degree of similarity between the erroneous input and each previously entered input is determined by a computational method that quantifies similarities between the failure script and each script generated from a previously entered input. The system revises the erroneous input to more closely match the most-similar previously entered input and resubmits the corrected input. The results of the resubmission are used to train the system to more accurately correct future input errors.

Abstract: The present disclosure discloses a method and an apparatus of account login to solve the problem of low efficiency of account login in existing technologies. A client of the method captures an image of a first credential of a user, recognizes user information of the user that is included in the captured image, includes the recognized user information into a login request, and sends the login request to a server for logging into an account that corresponds to the user information. Through this method, a user does not need to input his/her username when using a client for account login, but perform the account login by directly capturing an image of a first credential using an image capturing device of the client, thus effectively improving the efficiency of account login.
