Load i2b2 tables into the database(s) used for the project as needed, making sure to update db properties file with the  db parameters (e.g., 3.4 Crcdata Tables3.7.4 Load Metadata Tables). For example, you might specify an existing database in the ontology db-lookup, but a new database in the CRC db lookup. In this case, you only need to create/load the tables in the CRC database.
