Systems and methods for generating dynamic quick actions for an application in a web browser. The dynamic quick actions correspond to various functions of an application accessible via a web browser sidebar interface. When a hover event is detected in association with an icon of the application, a quick-actions card is generated that includes quick actions of the application from which the user can select. For instance, a selection of a quick action triggers the web browser to execute an action that causes the application function to be performed. Thus, application functions are able to be surfaced and controlled via a single input device selection (e.g., a mouse click).

Dynamically configured quick actions in a sidebar

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.
