Abstract

A device may include one or more memories; and one or more processors, communicatively coupled to the one or more memories, to receive a query for data stored by a database; generate an abstract syntax tree based on the query; determine whether the abstract syntax tree matches a list, where the list identifies one or more abstract syntax trees corresponding to queries or types of queries; and selectively perform an action based on whether the abstract syntax tree matches the entry of the list.
