The gas data model is a configuration of the utility network that includes all the feature classes, asset groups/asset types, rules, and associations needed to get started with a utility network. The data dictionary displays the gas data model and shows how each feature class has been designed. The data dictionary provides an overview of the fields and asset groups included in each feature class and models the concept of field reuse to reduce database size and improve responsiveness. The data dictionary includes a description of the elements in the Gas Utility Network Configuration. It will help you understand what elements are used to create the utility network and provide a description of what they are.
The data model included with the Gas Utility Network Configuration follows a set of design standards intended to optimize performance while using subtypes or asset groups to model complex networks. The data dictionary also includes the design standards of the data model, including the concept of field reuse, which outlines how the same field can be reused for different purposes.
With field reuse and the design of the electric data model, looking at database fields and their aliases may not provide a full understanding of how the field is being used. To determine if and how a field is reused, refer to the data dictionary.
