面向对象数据库无缝的C^＋＋应用编程界面

关系数据库与程序设计语言之间的松散耦合存在着编程范型及类型系统两方面的失配，是提高数据库应用软件之质量和生产率的极大障碍，面向对象数据库（ＯＯＤＢ）与程序设计语言（ＰＬ）的无缝结合旨在消除这种失配，本文以面向对象数据库管理系统原型ＯＳＣＡＲ为背景，提出ＯＯＤＢ与ＰＬ无缝结合的基本准则，ＯＯＤＢ无缝Ｃ＾＋＋应用编程界面的对象持久性模型，以及实现ＯＯＤＢ无缝Ｃ＾＋＋应用编程界面的关键技术。     

利用.PLT文件和PLOT绘制工程图形

ＰＬＯＴ是ＳＵＲＦＥＲ软件中一个图形输出程序，．ＰＬＴ文件则是由ＴＯＰＯ和ＳＵＲＦ形成的绘图文件。在ＳＵＲＦＥＲ绘图过程中发现，ＰＬＴ文件是由一组绘图命令组合的。根据其结构可以用高级语言编制类型众多的绘图程序，扩展了ＳＵＲＦＥＲ的绘图功能。本文就．ＰＬＴ文件的形成和ＰＬＯＴ绘制图形作了探讨。

Rule-Based Programming with Diaplan

Diaplan is a language for programming with graphs and diagrams that is currently being designed and implemented by the authors. In this paper, a programming example, declaration grids, shall illustrate how Diaplan supports a functional and object-oriented style of programming. The example also indicates which features are needed beyond those discussed in previous work on the language [B. Hoffmann, Abstraction and control for shapely nested graph transformation, Fundamenta Informaticae 58 (2003) 39–56].     

Reactive C: An extension of C to program reactive systems

Reactive systems are interactive programs that react continuously to sequences of activations coming from the external world. Reactive programming leads to a new programming style where one programs in terms of reactions to activations and reasons in a logic of instants. This paper describes an extension of the C programming language called RC (for ‘Reactive C’) to program reactive systems. The language RC is described, then some programming examples are given to illustrate the reactive approach. The main RC notions come directly from the Esterel synchronous programming language. Finally, the Esterel and RC languages are compared.     

Indent软件在编程风格教学中的应用

程序设计基础课程要注重培养学生良好的编程风格及习惯,但是现在编程风格教学现状却不容乐观。为使教师从繁重的指导工作中解脱出来,我们在编程风格教学中试验性地引入开源软件Indent,提高学生对编程风格学习的兴趣。     

Q'Nial: A portable interpreter for the nested interactive array language,Nial

The Q'Nial interpreter combines ideas from APL and Lisp implementations to provide a rich programming environment that supports several paradigms of programming. The interpreter is structured to reflect the division of Nial semantics into levels corresponding to zero-, first-and second-order objects. The paper describes the design of the interpreter, discusses constraints imposed by the desire to achieve portability and comments on what has been learned in building an interpreter in this style.

Cognitive Differences Between Procedural Programming and Object Oriented Programming

Software development is moving from procedural programming towards object-oriented programming (OOP). Past studies in cognitive aspects of programming have focused primarily on procedural programming languages. Object-oriented programming is a new paradigm for computing. Industry is finding that programmers are having difficulty shifting to this new programming paradigm. Findings in prior research revealed that procedural programming requires Piaget's formal operation cognitive level. New from this research is that OOP also requires Piaget's formal operation cognitive level. Also new is that OOP appears to be unrelated to hemispheric cognitive style. OOP appears to be hemispheric style friendly, while procedural programming is preferential to left hemispheric cognitive style. The conclusion is that cognitive requirements are not the cause for the difficulty in shifting from procedural to OOP. An alternative possibility to the difficulty is proactive interference of learning procedural programming prior to learning object oriented programming.
