# 3.4.5 Load Crcdata Tables

# Step 5: Load Data Repository (CRC) Tables

The **fifth** and **final step** in the Crcdata installation process is to load the data into the demodata tables by running the following command:

Important

- The demodata provided in the data package is a sampling of demonstration patients and observations that are by no means based on real patients. Also included is a sample of concepts, modifiers and providers that coincide with the Metadata that is loaded during the Metadata tables section.

- The data provided is intended to provide you a sample of how you may setup the Crcdata tables.

- If you have your own data and wish to load it instead of the i2b2 sample demodata you can do it at this point of the installation.

***Select the command line that is appropriate for your environment.***

  **Linux Run Command**

ant -f data_build.xml db_demodata_load_data

  **Windows Run Command**

%ANT_HOME%\bin\ant.bat -f data_build.xml db_demodata_load_data

Note

The loading of the Crcdata may take an extended period of time (20 minutes) due to the amount of sample data provided.
