Supersedes page ii of MlL-STD-1821, dated 17 June 1993. ii Licensed by Information Handling ServicesFOREWORD 1. The purpose of this standa

18、rd is to define the Standard Simulator Data Base (SSDB) Interchange Format (SIF). 2. The Standard Simulator Data Base (SSDB) is the central repository of validated simulator databases for the DoD training simulation community. The SSDB was developed under an Air Force program called Project 2851 (co

19、ntract F33657-86-C-0182). Tri-Service coordination has been maintained via the Joint Technical Coordinating Group for Training Systems and Devices (JTCG-TSD). The SSDB will be maintained at the DoD Simulator Data Base Facility (SDBF). 3. The SIF will serve as an input/output vehicle for sharing digi

20、tal simulator databases via the SSDB. Database builders may be tasked to supply their databases to the SDBF in this format. The SDBF would then be responsible for integrating the databases into the SSDB, from which data may later be extracted for use by other simulator systems, in either SIF or Gene

21、ric Transformed Data Base (GTDB) format. This will allow the Government to re-use databases created for specific simulation programs. 4. This standard defines two different versions of SIF, in order to support two different scenarios for sharing of SSDB data. In one form, the SSDB can be made availa

22、ble in its complex internal system-specific format to support distributed maintenance by SDBF-compatible data base systems, or to support autonomous but SSDB-compatible data base production by training system programs. In SIFs other form, there will be a mechanism for passing the essential contents

23、of simulator data bases, including the SSDB, for use or maintenance on systems with significantly different software than the SDBF. The “SSDB Interchange Format for Distributed Processing (SIF/DP)“ has been defined to handle the first situation, while the “SSDB Interchange Format for High Detail Inp

24、ut/Output (SIF/HDI)“ has been defined for the second. 5. The two SIF formats, SIF/DP and SIF/HDI, are logically identical but differ in physical format. Use of one format where the other would be more appropriate is likely to cause the implementing program to incur unnecessary costs. It is therefore

25、 important that the SIF user possess an understanding of the distinction between the two alternatives, before specifying either for use. 6. When it is required that a simulator program receive database inputs from the SDBF, a third format may be used. This third format designated the Generic Transfo

26、rmed Data Base (GTDB), is documented in MIL-STD-1820. The GTDB is strickly an output product format of the SDBF and is a more thoroughly processed database than SIF. It is capable of supporting a much greater range of data selection and formatting options than either SIF/HDI or SIF/DP. GTDB should b

27、e considered for use instead of SIF when the receiving system wishes to minimize post- processing of the data. iii Licensed by Information Handling ServicesPARAGRAPH 1 . 1.1 1.2 1.3 1.4 1.5 2 2.1 2.1.1 2.1.2 2.2 2.3 3 3.1 3.2 4 4.1 4.2 4.2.1 4.2.1.1 4.2.1.2 4.2.2 4.3 4.3.1 4.3.1.1 4.3.2 4.3.2.1 4.3.
