A form of implementation is described that allows extending the capabilities of a database by using layers levels, emphasizing in the concept of inheritance. What is described is illustrated by an example applied to the Peruvian reality, which is shown with a certain level of detail.application/pdfenginfo:eu-repo/semantics/openAccessAttribution 4.0 Internationalhttps://creativecommons.org/licenses/by/4.0/Fuzzy databaseInheritance of classesData typeBase de datos difusaHerencia de clasesPossibility of occurrenceTipo de datosBase layersPosibilidad de ocurrenciaCapas baseClass hierarchyJerarquía de clasesinfo:eu-repo/semantics/articlehttps://doi.org/10.17577/ijertv5is110170https://purl.org/pe-repo/ocde/ford#2.00.00
