Model-View-Controller (MVC) pattern is very useful and popular design pattern that separates the modeling of the domain, the presentation, and the actions based on user input into three separate classes. The model acts as the domain that software is built around, the view as the visual representation of a model. It is usually the resulting markup that the framework renders to the browser and the controller...
Although the popularity of activity-centric process management systems (PrMS) has increased during the last decade, there still exist business processes that cannot be adequately supported by these PrMS. A common characteristic of these processes, which is neglected by current activity-centric PrMS, is their need for object-awareness, i.e., the explicit processing of business data and business objects...
The use of spreadsheets to implement Information Systems is widespread in industry. Scripting languages and ad-hoc frameworks (e.g., Visual Basic for Applications) for Rapid Application Development are often exploited by organizations to quickly develop Spreadsheets-based Information Systems for supporting the information management of their business processes. Maintenance tasks on these systems can...
The code reuse technology based on the MVC framework is studied while implementing a project named "The comprehensive service system of fishing vessel inspection." Based on the concept of MVC, common reuse methods used in the project is illustrated from seven aspects, i.e. the inheritance reuse of master page in the View, layout code reuse in the web page design, login reuse in the Controller,...
Pen-based e-form is a style of office software in the era of Post-WIMP interface. It is complicate and difficult to utilize the existing development tool to implement pen-based user interface, so that pen-based e-form only can be designed and implemented by the professional developers, which make it is difficult for the pen-based e-form software to adapt to the changing user requirements. Given the...
Testing a database application is a challenging process where both the database and the user interaction have to be considered in the design of test cases. This paper describes a specification-based approach to guide the design of test inputs (both the test database and the user inputs) for a database application and to automatically evaluate the test adequacy. First, the system specification of the...
User Interface UI is an old subject, but is still a hot research topic. A lot of efforts were put into making the life of designers and authors of UI easier. Declarative UI languages were a major approach for defining and developing UI. The integration and implementation of a standardized presentation layer is the main focus of the work presented here. This paper presents some new development for...
Program development concepts are highly dependent on software architecture, complexity of algorithm, re-usability purposes, efficiency, efficacy, etc. The evolution of SAP development concepts reflects the changes through important milestones, such as mainframe, client-server and service-oriented architecture. Those issues can easily be resolved by making new programs which were impossible to handle...
The technique of vertical slicing was introduced as a mechanism to combat our agile software development teams developing tendency toward building software in horizontal layers, building one service at a time, or grouping stories then breaking them down into layers. Those practices resulted in sprint reviews where no functionality could be demonstrated to the users and several iterations before all...
An increasingly important class of software-based systems is platforms that permit integration of third-party components, services, and tools. Service-Oriented Architecture (SOA) is one such platform that has been successful in providing integration and distribution in the business domain, and could be effective in other domains (e.g., scientific computing, healthcare, and complex decision making)...
In today' intensely competitive environment, traditional application systems such as ERP, lacks the autonomy and flexibility required by dynamic market. Given that, more and more companies are offering their software by Software as a Service (SaaS) application platform. Most SaaS platforms are implemented by traditional J2EE programming. This paper introduces a new well-designed SaaS application platform...
Performance engineering for informational and transactional distributed systems must take into account both the development and runtime information about the target system and its environment. At development time, the architects have to choose from many architecture styles and consider all performance requirements across a multitude of workload. At runtime, an Autonomic Manager has to compensate for...
The digital museum of university is conducive to the preservation and utilization of precious cultural assets. This thesis describes the framework of a digital museum platform of university based on DSpace, including data models, metadata, searching and browsing, user interface, as well as the secondary development of DSpace platform and localization work. The platform, put into application in Beijing...
This article presents paradigms for mobile applications and introduces a model-based development process, by which they can be effectively developed. With the proliferation of mobile devices such as Apple® iPhone® or BlackBerry®, business processes may be implemented in a mobile environment. Mobile applications operate in environments that place high demands on ergonomics and performance and are very...
The integration of services into business applications within enterprise services is needed in on-premise settings as well as in upcoming on-demand enterprise settings. Today, it is typically performed in manual integration projects by highly skilled integration experts on the consumer side. As consumers demand flexible and adaptable enterprise systems with lower total cost of ownership (TCO), enterprise...
Efficiency in data manipulation is of vital importance to ERP systems. A Flexible data manipulation application programming interface (API) helps to address a number of acute needs of application developers and eventually end users. Building on the notions of business objects and Web services, this paper contributes the design and implementation of a business object query language (BOQL). Essentially,...
As the progress of information technology, some financial systems used for long time can no longer meet the requirement of customers in both user interface and business process, and need reengineering imminently. In order to save the human resource and financial effort, this article raises a reengineering approach by encapsulating the back-end data access code of legacy system and only refactoring...
SOA (service-oriented architecture) is a component model, which can integrate the different function modules by defined interfaces in system. SOA technology has been used wildly in the field of enterprise realized the enterprise applications integration. Struts is an structure of MVC based on SOA, using J2EE based on the combination of Struts framework and Web application to develop information management...
PHP is one of the leading Web development languages, however, the development model of existing PHP organizes without a structure, which mixes the code of data access, the processing of business logic , and Web presentation layer together, as a relult, it brought about many problems in the Web applications , meanwhile, it could not meet the rapid development of Web apply any more. In this paper, a...
The complexity of data-intensive business processes is typically reflected in the user interfaces of the information systems supporting them. To facilitate ease of use despite the visual and semantic complexity of dialog forms, users should be guided in ways such as highlighting and describing invalid input, showing/hiding or enabling/disabling particular UI widgets. Manual implementation of the rules...
