Ontological modeling for software application development

The analysis of application for software development is usually guided and, hence, constrained by concepts and constructs of structured and object-oriented programming languages. It produces an analysis model that bears no essential difference from a software design. Here, we introduce an ontological Weltanschauung in application analysis for understanding essentials and novelties, which are obscured in structured and object-oriented methods of application analysis. The ontological viewpoint is reified with a systemic framework, or simply an ontology, which can be related to software design. Thus, we can apply ontological analysis in software development.     

Missing in action: information hiding

Information hiding is characterised by the idea of “secrets”-design and implementation decisions that a software developer hides from the rest of a program. It is part of the foundation of both structured and object-oriented design. In structured design, information hiding produces “black boxes”; in object-oriented design, it gives rise to the concepts of encapsulation and modularity, and is associated with abstraction. However, information hiding doesn't require or depend on any particular design methodology, and you can use it with any design approach. As incremental, evolutionary development styles become more popular, the value of information hiding can only increase     

The object-oriented structured design notation for software designrepresentation

The development of a notation that supports key software structure concepts and design principles, is discussed. The notation should let designers represent modules, interfaces, hidden information, concurrency, message passing, invocation of operations and overall program structure in a comprehensive way. The authors examine three categories of approach to architectural design: object-oriented design, functional decomposition, and data structure design. They present their design notation, called object-oriented structured design (OOSD) which achieves the above-stated goal. They discuss classes in OOSD, its handling of asynchronous processes, and its design methods and rules. Automated support for OOSD is considered     

A tutorial and review of object-oriented design of manufacturing software systems

Object-oriented design represents a relatively new method of software system design that provides a means for the development of robust software systems. This approach is what software developers need to deal with the dynamic nature of the manufacturing organization and the processes contained within. This paper presents a tutorial which focuses on the application of object-oriented design and programming to manufacturing software development. This essay begins with an examination of object-oriented software design (OOD) and how it compares with traditional algorithmic design. The discussion reviews the major elements of an object-oriented system and discusses how these elements support the development of complex software systems using examples from manufacturing as support. This is followed by a discussion of the steps to use as one approach to object-oriented design. The paper concludes with a review of object-oriented manufacturing systems reported in the literature.

Object-oriented design and programming in medical decision support.

The concept of object-oriented design and programming has recently received a great deal of attention from the software engineering community. This paper highlights the realisable benefits of using the object-oriented approach in the design and development of clinical decision support systems. These systems seek to build a computational model of some problem domain and therefore tend to be exploratory in nature. Conventional procedural design techniques do not support either the process of model building or rapid prototyping. The central concepts of the object-oriented paradigm are introduced, namely encapsulation, inheritance and polymorphism, and their use illustrated in a case study, taken from the domain of breast histopathology. In particular, the dual roles of inheritance in object-oriented programming are examined, i.e., inheritance as a conceptual modelling tool and inheritance as a code reuse mechanism. It is argued that the use of the former is not entirely intuitive and may be difficult to incorporate into the design process. However, inheritance as a means of optimising code reuse offers substantial technical benefits.     

Object-oriented design: A goal-driven and pattern-based approach

In recent years, the influences of design patterns on software quality have attracted increasing attention in the area of software engineering, as design patterns encapsulate valuable knowledge to resolve design problems, and more importantly to improve the design quality. One of the key challenges in object-oriented design is how to apply appropriate design patterns during the system development. In this paper, design pattern is analyzed from different perspectives to see how it can facilitate design activities, handle non-functional requirement, solve design problems and resolve design conflicts. Based on the analysis, various kinds of applicability of design patterns are explored and integrated with a goal-driven approach to guiding developers to construct the object-oriented design model in a systematic manner. There are three benefits to the proposed approach: making it easy to meet requirements, helping resolve design conflicts, and facilitating improvement of the design quality.     

Intelligent simulation code generator: a relational database management approach

Although many studies have illustrated AI-based simulation, the concept of combining databases with AI and simulation is relatively new. Complementing AI and simulation with databases aids in the development of a completely integrated simulation environment that spans the whole simulation life cycle. This study illustrates the design of a simulation program generator, the intelligent simulation code generator (ISCG), which uses a database management system as the user-oriented interface, an object-oriented system to develop the knowledge base and simulation environment, and a target simulation language as the simulation software. The ISCG offers data independence, system independence, simulation-specific transparency, and target language neutrality. Furthermore, the ISCG offers system design flexibility.

We summarize work on WebComposition, a model for Web application development, then introduce the WebComposition Markup Language, an XML-based language that implements the model. WCML embodies object-oriented principles such as modularity, abstraction and encapsulation

Computer simulation of neural networks is an important part of this investigation. This paper applies concepts from an important trend in software engineering research, namely object-oriented programming, to model neural networks.The design and implementation of a software object library is crucial to obtaining the full benefits of object-oriented programming. In this paper we discuss the design and implementation of a foundation library of software objects for the purpose of simulating and validating different network architectures and learning rules. The library contains objects that implement various types of nodes and learning rules.
