Functional View 4.2.2 – Data
Distribution
§Considerations/Concerns Addressed:
Interfaces
How difficult is it to develop applications that use Core
System interfaces?
How flexible are Core System data distribution interfaces?
How does the Core System enable control of the services it
provides?
Functionality
How does the Core System monitor the services it provides?
How does the Core System function internally?
How do the Core System’s components work together?
How does the Core System transition between operational modes?
Security
What functional elements are involved in the detection of
misbehavior by System Users, and what roles
do those entities have?
How does the Core System maintain the integrity of information
provided to it by System Users?
Appropriateness
Does the Core System meet all of the needs defined in the
ConOps?
Does the Core System meet all of the functional requirements
defined in the SyRS?
Evolvability
How easily can the Core’s functionality be expanded to cover
new needs if they arise?
Does the functionality of the Core scale to support foreseeable
demands from System Users?
