PDS engineering attributes such as line number, temperature and pressure are stored in the PDS Design Database. This design database is a relational database and PDS communicates with this database via an interface called RIS (Relational Interface System). In addition to the design d atabase, the Intergraph PDS provider adapter also needs access to the Project Control Database. The Project Control Database maintains amongst other things the model indices which are required to associate the model to the appropriate database tables. Both the Model Data and Design databases can be exported/dumped into an ASCII file (RIS Dump File). These RIS dump files are being used by the Intergraph PDS provider adapter to obtain attribute information and project control information.

The RIS dump files can be created through an Intergraph supplied utility called "RIS Unloader" (risunload.exe).
RIS Unloader will prompt for the target RIS dump file name and for the schema and table names. The user should enter the schema names for the design database and project control database. The names of the schemas are project dependant.

For the project control database, you should specify the following tables:

  • pdtable_112,
  • pdtable_113

    but may also specify [a] (ALL) for all tables.

For the design database, you should specify the following tables (for each model):

  • pdtable_12_*,
  • pdtable_34_*,
  • pdtable_50_*,
  • pdtable_67_*,
  • pdtable_80_*

    but may also specify [a] (ALL) for all tables.

The Intergraph PDS provider adapter does not require indexes, views and priviliges to be exported to the RIS dump file. If the RIS dump file does contain this information it will be ignored by the adapter. The PDS provider a Adapter supports both fixed and variable formatted RIS dumps.
