-# umls_loading_postgresql
+# Loading Unified Medical Language System® (UMLS®) tables on PostgreSQL
+![UMLS explan](https://images.slideplayer.com/18/6112070/slides/slide_2.jpg)
+These scripts allow us to load all UMLS tables generated by the Metathesarus (RRF files).
+
+The original scripts were found at https://www.nlm.nih.gov/research/umls/implementation_resources/community/index.html
+
+Minor modifications were required to some table fields types to accomodate UMLS2018AA.
+
+Developed and tested on: PostgreSQL 9.24 and UMLS2018AA on CentOS 7.
