Sažetak
This paper summarizes our efforts in implementing a working multi-level secure database prototype. We have chosen Belief-Consistent Multilevel Secure Relational Data Model (BCMLS) as a basis for our prototype because of its comprehensive semantics for interpreting all stored information. While semantically superior to other models, this model has not been implemented as a working system before. Our prototype, which was created on an Informix database server with a PHP web client, enables insertion, deletion and update of multi-level data while addressing the underlying model complexities through a number of original solutions.
