**HARDWARE REQUIREMENTS**

- Space requirements are dependent on the size of the raw databases being used.
- To create CDM, you will need 3 times as much freespace as the size of the database.
- Data can be stored in either SAS or RDBMS; the OMOP Research Lab stores data in both SAS and Oracle.
- You will need an additional 3 times the size of database for tempspace (TEMP, UTILLOC) to run the methods.
- For running methods: minimal recommendations include 20 processors, 64-bit OS (Windows or Unix), 32-gigabytes of RAM.

**SOFTWARE REQUIREMENTS**

SAS is the minimal software requirement with some analysis methods requiring additional software packages. The OMOP tools and procedures listed below are listed with software dependencies.
