Privileged structures, definition

In a recent review, Muller discusses the privileged stracture concept and highlights several paradigms of these structures. The definition of privileged structure can be easily confused with the concept of recurrent structural element. While some recurrent elements can be desirable, those that result in hits across many screens can generate irrelevant compounds or false positives, which should obviously be avoided. 

The contribution of this paper is the definition of four different kinds of components for distributed event collection, according to the way they interact with the database and with the outside world. It also generically defines three types of information that are handled by the application. This structure is very important in terms of security, because it allows a strong separation of privileges at the table and column level (for databases that support it), between insertions, modifications, access and deletion. We are also able to effectively leverage the consistency mechanisms of SQL (foreign keys and references) to ensure that event information remains consistent over time.
