End-User Computing in a CASE Environment

Computer-aided software engineering (CASE) tools are currently being used by IS professionals rather than by users. No matter how effective these tools may be, however, they will not be able to assist in the reduction of application backlogs without supporting user-driven applications. This article examines characteristics of a CASE environment from the various perspectives of decision support, identifies the advantages and limitations of end-user computing in this environment, and suggests how IS managers can realize the potentials of CASE for user applications.     

Software tools for safety-critical software development

We briefly present a software methodology for safety-critical software, developed over many years to cope with industrial safety-critical applications in the Canadian nuclear industry. Following this we present discussion on software tools that have been used to support this methodology, and software tools that could be used, but have not been used for a variety of reasons. Based on our experience, we also present and motivate a list of high-level requirements for tools that would facilitate the development of safety-critical software using the presented methods, together with a small number of tools that we believe are worth developing in the future.     

Porting Ada: a report from the field

With the constant barrage of new systems, porting software applications is inevitable. This article takes a look at the problems involved in porting an Ada/C application. The porting effort begins when the software architecture is defined and the code implemented. The task is completed with the successful execution of the software on all target platforms. The AFATDS porting effort to the HP RISC platform was completed successfully. The effort to port AFATDS to an InteVSCO Unix platform is still incomplete and is awaiting an Ada compiler upgrade that can pass the AFATDS messaging schema's large arrays to generic procedures. With the numerous operating systems available, the constant barrage of new operating system releases, and the continual hardware advancements, the need to port software applications is evident. The success of any porting effort depends on the maturation and reliability of the tools being used. If the Department of Defense's dual-use strategy is to succeed, DoD must also foster the development of reliable and affordable Ada tools     

Advances in software engineering

Software is the key technology in applications as diverse as accounting, hospital management, aviation, and nuclear power. Application advances in different domains such as these-each with different requirements-have propelled software development from small batch programs to large, real-time programs with multimedia capabilities. To cope, software's enabling technologies have undergone tremendous improvement in hardware, communications, operating systems, compilers, databases, programming languages, and user interfaces, among others. In turn, those improvements have fueled even more advanced applications. Improvements in VLSI technology and multimedia, for example, have resulted in faster, more compact computers that significantly widened the range of software applications. Database and user interface enhancements, on the other hand, have spawned more interactive and collaborative development environments. Such changes have a ripple effect on software development processes as well as on software techniques and tools. In this article, we highlight software development's crucial methods and techniques of the past 30 years

JSMAA: open source software for SMAA computations

Most software for multi-criteria decision analysis (MCDA) implement a small set of compatible methods as a closed monolithic program. With such software tools, the decision models have to be input by hand. In some applications, however, the model can be generated using external information sources, and thus it would be beneficial if the MCDA software could integrate in the comprehensive information infrastructure. This article motivates for the need of model generation in the methodological context of stochastic multicriteria acceptability analysis (SMAA), and describes the JSMAA software that implements SMAA-2, SMAA-O and SMAA-TRI methods. JSMAA is an open source and divided in separate graphical user interface and library components, enabling its use in systems with a model generation subsystem.

The article concludes with a listing of code for basic computer vision techniques.     

An experience report on the verification of autonomic protocols in the cloud

Cloud applications are often complex distributed applications composed of multiple software components running on separate virtual machines. Setting up, (re)configuring, and monitoring these applications are complicated tasks because a software application may depend on several remote software and virtual machine configurations. These management tasks involve many complex protocols, which fully automate these tasks while preserving application consistency as well as some key properties. In this article, we present two experiences we had in formally specifying and verifying such protocols. The first one aims at designing a reconfiguration protocol of a component-based platform, intended as the foundation for building robust dynamic systems. The second aims at automating the configuration task of a set of virtual machines running a set of interconnected software components. Both applications are specified using the LNT process algebra and verified using the CADP verification toolbox. The use of formal specification languages and tools was a success. We conclude with a number of lessons we have learned while working on this topic in the last 3 years.

When elephants dance, mice watch out! [legal issues]

Bristol Technology develops software tools-in particular cross-platform tools that software developers use to port applications software to Unix from other operating system platforms. Bristol had an agreement with Microsoft to get access to technical information about the Win98 application interfaces (APIs), the means for causing applications software to interact with the operating system. According to Bristol, its Wind/U tool was making it too easy for developers to write Unix programs that could also run under NT. Microsoft therefore used pretexts to deny Bristol access to the updated APIs for Windows NT 5, the operating system that will follow Win98 (probably under the name Windows 2000). Microsoft denies that it is doing any more than trying to gain a fair price for the crown jewels of its intellectual property. Yes; Microsoft is demanding four times as high a fee for access to the source code needed to use the NT APIs, but NT code is worth much more than that for Win98 or Win95. The article focuses on the ensuing legal battle between Microsoft and Bristol Technology     

Experiences developing architectures for realizing thin‐client diagram editing tools

Diagram‐centric applications such as software design tools, project planning tools and business process modelling tools are usually ‘thick‐client’ applications running as stand‐alone desktop applications. There are several advantages to providing such design tools as Web‐based or even PDA‐ and mobile‐phone‐based applications. These include ease of access and upgrade, provision of collaborative work support and Web‐based integration with other applications. However, building such thin‐client diagram editing tools is very challenging. We have developed several thin‐client diagram editing applications realized as a set of plug‐in extensions to a meta‐tool for visual design environment development. In this paper, we discuss key user interaction and software architecture issues, illustrate examples of interacting with our thin‐client diagram editing tools, describe our design and implementation approaches, and present the results of several different evaluations of the resultant applications. Our experiences will be useful for those interested in developing their own thin‐client diagram editing architectures and applications. Copyright © 2007 John Wiley & Sons, Ltd.

A framework for efficient and rapid development of cross-platform audio applications

In this article, we present CLAM, a C++ software framework, that offers a complete development and research platform for the audio and music domain. It offers an abstract model for audio systems and includes a repository of processing algorithms and data types as well as all the necessary tools for audio and control input/output. The framework offers tools that enable the exploitation of all these features to easily build cross-platform applications or rapid prototypes for media processing algorithms and systems. Furthermore, included ready-to-use applications can be used for tasks such as audio analysis/synthesis, plug-in development, feature extraction or metadata annotation. CLAM represents a step forward over other similar existing environments in the multimedia domain. Nevertheless, it also shares models and constructs with many of those. These commonalities are expressed in the form of a metamodel for multimedia processing systems and a design pattern language.     

Building a database design laboratory on the Internet

Commercial tools for software engineering include many development environments to support the design process. These integrated tools are usually distributed through traditional retail channels, with vendors increasingly giving customers the option of downloading products from the Web. The tools are installed on user client machines and are usually duplicated for actual tool use at customer sites. Users are responsible for installation, maintenance and upgrade procedures. We developed Web Lab as part of a project sponsored by the European Commission to advance rule-based, object-oriented technologies for developing database applications. The Web Lab was designed to help disseminate the research results. It enables remote use of a design environment for database applications, including a repository for application development that provides a protected workspace. However, as software becomes more and more a commodity, we expect vendors to begin selling software use rather than tools, an option that is particularly attractive in the context of thin clients running on network computers. Web Lab demonstrates the feasibility of this idea for commercial software distribution. We describe the Web Lab project, its implementation, and plans for further development     

Developing Java-AWT thin-client applications for limited devices

Developing software for personal wireless devices (PWDs) requires new methods and tools that address the restrictions introduced by these devices' mobile nature. The thin-client applications for limited devices (TCPTE) framework supports the development of thin-client applications for mobile devices with limited resources. Using TCPTE, we can execute Java applications on a server and display their AWT interfaces on a remote client. TCPTE combines the advantages of thin-client computing with the richness of client-server graphical interfaces and lets programmers develop applications for PWDs using the same processes and tools they typically use for desktop applications.
