Abstract
The subject of this article refers to the choice of objects participating in the learning process, the objects attribute definition, the objects relationship analysis and the ER-model of a data base containing students results. Protocols based on relational tables as well as those resulting from an interaction between the tables and the learning tree, are described. The subject area semantics is taken into account.
