Abstract (English)	The need to preserve databases has been approached in the past; however, the need to preserve database concepts is new. In this article, by database preservation, we intend keeping a structure where all and only the concepts related with the database are retained; keeping the logical coherence among these concepts and relating the structure with the logical database models. The concept structure, called ontology for database preservation (Locuratolo & Palomäki, 2013) results in leaves which are incompatible concepts; encloses all and only the concepts related to the initial concept structure; encloses all and only the intensional inclusion relations between concepts. The concept structure has been mapped to statically logical schemas; this paper shows that the logical schemas can be extended to handle dynamic situations.
