The BrDR installation will install two Microsoft SQL Server 2012 database files. Both database files contain the BrDR database schema (tables and relationships) and are populated with system data. The AASHTOWareBr68.mdf file is the production database and is populated with template bridges. The AASHTOWareBr68s.mdf database is the sample database and is populated with sample bridges. The template bridges and samples bridges describe the same bridges. See the BrDR on-line help for a description of a template bridge.
