8、fying Software Behavior.) The 1175 family of standards This standard is a member of the 1175 family of IEEE standards. The members of this family are listed below. NOTEReferences to “P1175.x“ in this standard refer to members of the 1175 family of standards that were not yet approved at the time tha
9、t this standard was balloted. This family of standards replaces IEEE Std 1175TM-1991, IEEE Standard Reference Model for Computing System Tool Interconnections.1 IEEE Std 1175-1991 was advanced to a full-use standard in 1994. It covered a number of closely related subjects, and the scope of material
10、contained was able to serve a number of divergent interests. This revision restructures and substantially augments the material in IEEE Std 1175-1991. It has been divided into sev- eral individually useful documents in order to facilitate its use by different communities of interest. These guides, r
11、ecommended practices, and standards generally address issues involved in characterizing the kinds of interconnections that exist between a computing system tool and its environment. Although particularly intended to address the imple- mentation and use of Computer-Aided Software Engineering (CASE) t
12、ools, the discussion of interconnections in this family actually has wider applicability to computing system tools in general, beyond only CASE tools. Four kinds of interconnections with a computing system tool are addressed: interconnections with organizations, users, platforms, and other computing
13、 system tools. Consideration of interconnections is important to understanding, selecting, implementing, and using computing system tools. Also, although most computing system tools do not need to communi- cate behavior descriptions of subject systems, their creators need to develop such description
14、s for them. A brief summary overview of each of the members of this family of standards is given below. A more complete over- view is available in IEEE Std 1175.1TM-2002, which provides an integrated overview of the members of the 1175 family of standards, and it describes the fundamental concepts t
15、hat provide a basis for organizing the material.

It appears in the standards listing on the I
18、EEE Xplore website (http:/ieeexplore.ieee.org/) as “IEEE Std 1175, 17 Aug. 1992,” with the title “IEEE trial-use standard reference model for computing system tool interconnections.” In 1994, the term “trial-use” was removed from the title when the standard was approved for full-use status. The 1994
19、 version, which was identical to the 1992 publication except for the title and minor editorial corrections, is not available on the IEEE website.

IEEE Std 1175.1-2002 Guide for CASE Tool InterconnectionsClassification and Description IEEE Std 1175.1-2002 is a guide to the IEEE 1175 family
21、of standards. It describes how these standards are intended to be used to accomplish the effective integration of computing system tools into a productive engineering environment and sets forth the fundamental concepts on which these standards are based. These concepts establish the integrating fram
22、ework for the other members of this family of standards. IEEE Std 1175.1-2002 describes the scope of application of each member standard, the various issues addressed in that standard, and the interrelationships between the family members. IEEE P1175.2 Recommended Practice for CASE Tool Interconnect
23、ions Characterization of Interconnections IEEE P1175.2 presents four perspectives on a computing system tools interconnections that offer insight into the opera- tional problems of interconnecting computing system tools with their environment. IEEE P1175.2 establishes recommended collections of stan
24、dard contextual attributes describing relationships between a computing system tool and its organizational deployment, its human user, its executable platform, and its peer tools, as illustrated in the figure below. These contextual attributes are of the “news-story” form: who, what, when, where, wh
25、y. The values of these con- textual attributes are references to organizational, industrial, and professional standards. By assisting users to reach a clear understanding of the context of operation for a computing system tool, IEEE P1175.2 contributes to the effective implementation and application
26、 of computing system tools.

All rights reserved.v IEEE Std 1175.3-2004 Standard for CASE Tool InterconnectionsReference Model for Specifying Software Behavior (this standard) This standard is an expansion of Par
28、t 3 of IEEE Std 1175-1991. It focuses specifically on a common set of modeling concepts found in commercial CASE tools for describing the operational behavior of a software product, and it provides a formal, logical model for describing this behavior. This standard also defines a Semantic Transfer L
29、anguage (STL) for communicating software behavior descriptions from one tool to another. A notable feature of the STL is its design for human readability, which makes STL text files suitable for use in software design reviews by users unfamiliar with com- puting system tool diagramming notations. In
30、 addition, the design of the STL syntax readily permits analysts to prepare and edit STL descriptions using a text editor or word processor. To permit backward compatibility with Part 3 of IEEE Std 1175-1991, this standard makes no changes to the STL syntax or to the rules for conformance to this sy
31、ntax as originally defined in Part 3 of IEEE Std 1175-1991. However, some aspects of the 1991 syntax that were previously left as user defined have now been specified in order to increase the con- sistency and reliability with which the STL may be used for exchanging software specification informati
32、on. In addition, improvements have been made in how the STL syntax is defined and explained. Finally, the STL Interconnection Profile has been replaced with more straightforward, more “user-friendly” tabular and comma-separated-value formats to define a Tool Interconnection Profile that can serve th
33、e same purpose as the original form of the Profile. IEEE P1175.4 Standard for CASE Tool InterconnectionsReference Model for Specifying System Behavior IEEE P1175.4 encompasses the description of other computing systems supported by IEEE 1175.3-2004, but it goes fur- ther, providing a basis for repre
34、senting a wider variety of computing systems. Specifically, IEEE P1175.4 provides the necessary semantic elements for describing general hardware/software systems, including hardware-only, software-only, or mixed system components, and it allows these different types of components to be treated in a
35、 consistent manner. IEEE P1175.5 Standard for CASE Tool InterconnectionsSyntax for Transferring Behavior Specifications IEEE P1175.5 provides a structured syntax and a specific set of data elements that can be exchanged as a text stream or text file with users or other tools. This syntax permits des
36、cribing a systems operational behavior as an instance of the ref- erence meta-model in IEEE P1175.4. The figure below illustrates the relationship between the IEEE P1175.4 meta-model and the IEEE P1175.5 XML syntax in the context of the tooltool exchange of a computing system description. IEEE P1175
37、.5 also provides a logically equivalent human-readable syntax.
