Physical Flows

Overview

Physical flows describe what, when and how information is transferred over logical flows.

Model

The physical flow data model is comprised of several parts:

physical_flow - detail the mechanics of the flow - how often and over what transport
physical_specifications - describe at a high level what is in the flow
physical_spec_defn (_field / _sample_file) - describe the format of the data being transferred
physical_spec_data_type - describes the data types of the information transferred

Uniqueness of physical flows

Waltz currently considers the following set of attributes when determining if a physical flow is a duplicate:

Physical Specification Id
Physical Flow basis offset
Physical Flow frequency
Physical Flow transport
Logical flow id
