Process Plant Design Systems
1. Data centered systems,
The primary reference for the system is the Data Base, the data base in use is external to the design system, all models, components and specifications are expressions of structured data held in the data base.
The diagram below shows the growth of data on any given project in blue, the blue is also common to all aspects of the project, meaning that as data is generated in any part of the project it can be accessed by all in the project, use of an enterprise data base
2. File centered systems
Data growth locus for a File Centered system, note the diaspora of un connected data silos on the system, these cause blockages to data flow, and are reliant on premises based installations, that are are significant cost centers.
