COMPARATIVE ASPECTS OF SOFTWARE COMPLEXITY METRICS AND program modules - A MULTIDIMENSIONAL-SCALING APPROACH

SOFTWARE QUALITY JOURNAL 1992年第3期1卷 159-173页

作者： KHOSHGOFTAAR, TM MUNSON, JC RAVICHANDRAN, S FLORIDA ATLANTIC UNIV BOCA RATONFL 33431 UNIV W FLORIDA PENSACOLAFL 32514

A multivariate statistical procedure called multidimensional scaling is used to study the relationship of various software complexity metrics and program modules. The program modules that make up a software system are analysed and their effects towards the overall characteristics of a software are viewed. This multidimensional scaling technique is applied to a sample data set. The scaling procedure clustered the similar and dissimilar software complexity metrics. program modules with low complexity and few errors clustered together, while modules which were complex were isolated. This technique shows promise in the identification of complex modules that potentially contain disproportionate errors prior to the testing phase. The ability of the scaling techniques to cluster similar and dissimilar characteristics is explained and graphically presented.

Measuring nesting

Nesting is a fundamental and very commonly used programming construct. In many cases, the wise use of nesting contributes significantly to a programming team elegantly designing a solution to a difficult problem. However, the ease with which nesting constructs may be created and the essentially unlimited depth and breadth to which they may exist also enable a programming team to create programs that may be extremely difficult to understand and maintain. In this paper, nesting and nesting metrics are examined. The authors begin the nesting examination/discussion with a precise definition of the scope of programme selection nodes. The term 'nodes' instead of 'statements' is used because this work is done on control flow graphs of programme modules. Although there has been much work done on metrics related to nesting, there has not been significant work done on metrics that focus entirely on nesting. Explicit definitions for nesting depth and nesting breadth metrics are given for programme modules. The metrics are validated by comparing them to probably the best known nesting metric, the MaCabe cyclomatic metric. Also, the metrics are compared to the standard lines of code metric. Further, a new nesting concept, the nesting tree, is discussed and it is proposed that nesting trees themselves could be useful nesting measurement values.

TRIFORM programS

引用

COMMUNICATIONS OF THE ACM 1981年第6期24卷 344-350页

作者： CROCKETT, DW 908 North M Place Lompoc CA

The concept that three process functions—initialization, production, and completion—and a separate supervisory control function are sufficient to describe the execution of a program is the basis for Triform program design. Triform programs are composed of modules arranged in a trifurcate tree structure with each branch devoted to the performance of one and only one of the process functions. The root of the program tree is a control module which supervises process-function execution. Such trifurcate tree structures are shown to be minimum complexity structures.

Categorical ML - Category-theoretic modular programming

引用

Formal Aspects of Computing 1993年第4期5卷 337-366页

作者： Dennis-Jones, Esther Rydeheard, David E. Department of Computer Science The University Manchester M13 9PL Oxford Road United Kingdom

We consider an extension of the functional programming language Standard ML with a modular structure based upon concepts in category theory such as categories, functors, natural transformations and adjunctions. In essence, we are following the categorical imperative of considering arrows as well as objects. This is intended to enforce a certain mathematical rigour on the programmer, so that the only programs that can be expressed are those with a categorical significance. The essentially algebraic nature of category theory means that we may generate equational correctness conditions for the modular structure of programs, thus separating the correctness of individual functions from that of modules. We describe this programming language, give examples of its use, and explain how it is implemented in a type system. © 1993 BCS.

Designing Financial Information Systems for Auditability

引用

Journal of Management Information Systems 1984年第1期1卷 50-62页

作者： Lockman, Abe Minsky, Naftaly Assistant Professor Department of Computer Science Rutgers University Associate Professor Department of Computer Science Rutgers University

:Abstract:The auditing of results produced by computer-basedFinancial Information Systemsrequires that auditors be able to evaluate the internal controls of such systems. Because of the integrated nature of the components in current large systems, this has proven to be a quite formidable task. We propose the simplification of such evaluations through the incorporation,during the initial design of the system, of the sorts of basic control disciplines which are used in manual systems. Our approach involves the use of a powerful Authorization Mechanism control environment (based on computer science techniques for authorization and protection) to specify and enforce such control disciplines in a manner which is easily verifiable during the audit process.
