+Common-Data-Model / Oracle
+=================
+
+This folder contains the SQL scripts for Oracle. 
+
+In order to create your instantiation of the Common Data Model, we recommend following these steps:
+
+1. Create an empty schema.
+
+2. Execute the script `CDM V4 ddl.sql` to create the tables and fields.
+
+3. Load your data into the schema using the loading scripts in VocabImport
+
+Note: you could also apply the constraints and the indexes after loading the data, this will speed up the insertion of the data considerably.
