Product Definition. The Systems Data Exchange Matrix specifies the characteristics of the system data exchanged between systems. This product focuses on automated information exchanges (from OV-3) that are implemented in systems. Non-automated information exchanges, such as verbal orders, are captured in the OV products only.
Product Purpose. System data exchanges express the relationship across the three basic architecture data elements of an SV (systems, system functions, and system data flows) and focus on the specific aspects of the system data flow and the system data content. These aspects of the system data exchange can be crucial to the operational mission and are critical to understanding the potential for overhead and constraints introduced by the physical aspects of the implementation.
Product Detailed Description. SV-6 describes, in tabular format, system data exchanged between systems. The focus of SV-6 is on how the system data exchange is implemented, in system-specific details covering periodicity, timeliness, throughput, size, information assurance, and security characteristics of the exchange. In addition, the system data elements, their format and media type, accuracy, units of measurement, and system data standard are also described in the matrix.
SV-6 relates to, and grows out of, OV-3. The operational characteristics for the OV-3 information exchange are replaced with the corresponding system data characteristics. For example, the Levels of Information Systems Interoperability (LISI) level required for the operational information exchange is replaced by the LISI level achieved through the system data exchange(s). Similarly, performance attributes for the operational information exchanges are replaced by the actual system data exchange performance attributes for the automated portion(s) of the information exchange.
On SV-6, each operational needline is decomposed into the interfaces that are the systems equivalents of the needline. SV-1 graphically depicts system data exchanges as interfaces that represent the automated portions of the needlines. The implementation of SV-1 interfaces is described in SV-2 (if applicable). The system data exchanges documented in SV-6 trace to the information exchanges detailed in OV-3 and constitute the automated portion(s) of the OV-3 information elements.
A partial format for the SV-6 matrix can be found in CJCSI 6212.01B, and that format is required for C4ISP development. However additions to the CJCSI 6212.01B matrix to meet program-unique needs should also be allowed.
