The work is dedicated to the formalization of the conceptual database modeling stage by creating the mathematical model describing the components and their relationship with entities and attributes of database. Mathematical model is complemented by statistical measure of words occurrence - TF-index and takes into account the linguistic analysis of incoming documents describing domain being modeling. The proposed model allows formalizing the user support during conceptual modeling through using the document input tokens as entities and attributes of database. The algorithm of support can be implemented as a part of case-design tools for databases.
