Abstract: 1. Implementations of the present disclosure include receiving, by a database system, a query from an entity, providing a parse tree based on the query, the parse tree including nodes representative of operations to be executed and data objects stored within the database system, generating a module tree based on the parse tree, the module tree including a set of modules provided in sequential order from a root module to a leaf module, and executing an authorization check using the module tree by, for each module, determining a set of data objects and, for each data object in the set of data objects, determining whether the entity is one or more of authorized access the data object and perform an operation on the data object.

Abstract: The present disclosure involves systems, software, and computer implemented methods for determining and visualizing effective mask expressions. One example method includes identifying a request for an object in a software application. The request is associated with a particular user. An object hierarchy associated with the requested object is identified. At least one column in the object hierarchy is associated with a mask expression. A current dependent object in the identified object hierarchy is determined. Masking status data for the current dependent object is determined that identifies whether masking is to be applied to the current dependent object when fulfilling the request. The generated masking status data is used to determine which masking expressions are to be applied to which columns in the object hierarchy when responding to the request.
