Abstract
A method of accessing objects with fine-grained access control (FGAC) in a relational database management system (RDBMS) storing a segmented column-major database. For each object with access restrictions, an artificial neural network (ANN), is trained by generating an equally distributed segment map of segmented data entries, so that the map reproduces the row disposition in the unsegmented object. When a user access request is received, these ANNs are referred to determine if any of the objects to be accessed are subject to access restrictions. If that is the case, then the ANN creates a pseudo-view construct of its associated object which is limited to data entries that the user has permission to access. The pseudo-views are then injected into the user access request to embed the fine-grained access controls for subsequent processing of the request, which can then proceed without further regard to user-specific access restrictions.
