Accessing Data Stored In A Database System

A computer-implemented method for accessing data stored in a database system comprising a controller configured in such a way that the data is stored with relationships between data-elements of the data, and with enforcement of integrity of the data;

• wherein
• a first data-element and a second data-element of the data are stored in the database system with a relationship between the first data-element and the second data-element;
• wherein
• the first data-element is stored in the database system encapsulated by one or more first access-procedures so that the first data-element is accessible exclusively by calling the one or more first access-procedures;
• wherein
• the second data-element is stored in the database system encapsulated by one or more second access-procedures so that the second data-element is accessible exclusively by calling the one or more second access-procedures;
• wherein
• the database system further stores access authorization data indicating, at data-element level, whether access to second data-element is authorized to a first user identified in the database system through corresponding credentials that enable the first user to log in and operate in the database system;
• the method comprising:
• receiving, by the controller, a call by the first user to a first access-procedure of the one or more first access-procedures for attempting to access the first data-element, said first access-procedure of the one or more first access-procedures including a call to a second access-procedure of the one or more second access-procedures for attempting to access the second data-element based on the relationship between first and second data-elements;
• performing, by the controller, the call to said first access-procedure of the one or more first access-procedures;
• verifying, by the controller, whether the first user is authorized to access the second data-element according to the access authorization data;
• performing, by the controller, the call to said second access-procedure of the one or more second access-procedures;
• and
• returning, by the controller, a result of the attempt to access the second data-element, including an indicator of whether the first user is authorized to access the second data-element.
