Where Are Model Stored?

Sigmafine centralizes the storage of the Model and Case data using a Microsoft SQL Server. The Models are managed in this database through the Sigmafine Server. The Sigmafine Server keeps the history of the analysis data and the configuration of the model. Models can be presented in a suite of client-side tools for building, editing, and running analyses on the model.

When you use the Modeler to work on a model, the visual components are stored in ProcessBook files.

  • Files with a .pdi extension contain the information comprising a single display or model.
  • Files with a .piw extension contain a ProcessBook and all the displays of which it is composed.
  • Files with a .svg extension are scalable vector graphics files, typically for presentation in web pages.

Remember, all the visual information is stored in the ProcessBook display file (images of the elements, images of connections, XY coordinates of the elements, text objects in display file etc. The rest of the information which pertains to Model logic and configuration information like elements, their connections and the data etc. (which is not relevant to display) is stored in the Sigmafine Server.
