Historical Data Grinder 2.0

Abstract

Historical Data Grinder (HDG) is an EAV database model designed to store and aggregate historical information regardless of geographic space, chronological period, or topic of interest. The source code of the database is available open source at: https://github.com/angelalumezeanu/hdg_structure. This paper details the specificities of HDG within the framework of other digital tools focused on the history of Romania, describes the updates brought by version 2.0, and highlights its advantages compared to traditional relational databases. To exemplify the latter, it presents the procedure for ingesting a major data set: members of the Hungarian parliament elected in the Transylvanian constituencies between 1865-1918. The data set is available for the general public, along with other information from HDG, at www.hdgrinder.ro.
