Conference management applications have been widely used as examples for the study of conceptual schemas because of their manageable size and diversity of cases. However, as far as we are concerned, the conceptual schemas available only refer to the structural or static part of these systems. Therefore we have considered useful and necessary for our work to develop a whole specification, including the behaviour of a conference management application. The conceptual schema proposed in this paper is based on the study of the code of a real existing product: MYREVIEW. Additionally, this paper has also permitted to test or consolidate the real application of some proposals. The first group consists on alternate mechanisms to define integrity constraints and derived elements proposed by Olivé. The root of these proposals is the definition of constraint and derived elements by means of operations. Secondly, it aims at exploiting the benefits of modelling events as entity types proposed by Olivé. Finally, it also includes the distinction between domain events, action request events and query events in which Olivé and Raventós are currently working.
