A static copy of the AACT database is created on the first of each month. The most recent and archived copies are available for download. These can be used to create a local copy of a particular instance of the database. A number of query and analytic tools (such as SAS, pgAdmin & R) can then be used to connect to and query your local copy.
For those who prefer to access the data via simple flat files, static copies are also available as a zipped package of pipe-delimited files.
