Data View

The data view of a system of systems is a representation of the system from the perspective of data needs, and the data framework that needs to exist to support the INTERSECT architecture. The data view is a specification for all data aspects of INTERSECT as a whole system, and shall include the conceptual, logical, and physical data models. The conceptual data model provides the high-level data concepts and their relationships that are important to INTERSECT’s operations that meet its intended purpose. The logical data model bridges the conceptual and physical data models and introduces the data structure for needed components. The physical data model is the actual data schema and specifications for INTERSECT services and applications.

Some of the items associated with the data view are:

  • Overall data flow within the INTERSECT system.

  • Descriptions and definitions of data components.

  • Specification of the data messages, in XML Schema format, for command/control, data movement of bulk and streaming data.

  • Database schema for INTERSECT’s operational data.

Some of the items NOT associated with the data view are:

  • Specifications for scientific data (aka, the payload).

  • Specifications for instruments, resources, etc.

  • Experiment specifications.

This view should be read by software developers, database developers, software engineers, network engineers, project managers, and others who will need to understand the data necessary for an INTERSECT installation to operate and how that data is defined and exchanged.
