The databases in PCC are used to store the standard material properties, the standard component dimensions and the project related data.

The standard material and component database can be expanded by the user through the PCC software. The database file is locked to prevent misuse of the database. The standard component database is an integral part of the material database and contains the standard pipe components.

The project database is separate from the standard databases. This database stores the project data as entered and selected by the user. The database can be opened with MS Access. It is advised to only read from the database since changes might corrupt the database information or structure integrity.
