EVAbase: a personal collections database

I need a database to catalog and track my personal fossil and mineral collection. The structure of EVAbase is drawn from my experience using Specify (https://www.specifysoftware.org/) and MCZbase (a modified ARCTOS collection management system, http://arctos.database.museum/) and my evolving understanding of relational databases. Currently, EVAbase consists of a specimen table and an accession table. My next steps will be to incorporate a locality table and review field names for compliance with Darwin Core terms (https://dwc.tdwg.org/list/).
