PCS Axis is a database application used worldwide by distribution and transmission companies to manage pipeline compliance and integrity data. The application uses a SQL server database to store and manage data for one or more modules (Figure 2-5). All modules share a common interface that allows users to easily work with data regardless of which module they use. Modules are based on common industry practices and various Department of Transportation (DOT) regulations. These include DOT 192 titled Transportation of Natural Gas and Other Gas by Pipeline: Minimum Federal Standards Safety and DOT 195 titled Transportation of Hazardous Liquids by Pipeline.

The PCS Axis database is fully ODBC compliant allowing for integration with other databases, such as GIS (geographic information system) and ERP (enterprise resource planning) databases.
