Implementation Of SaaS Cloud Computing Services On E-Learning Applications (Case Study: PGRI Foundation School)

Learning activities in PGRI Foundation schools, especially in SMA PGRI Kudus still use the conventional model that is directly face to face, so it is necessary to develop online learning media or what is now often referred to as e-learning to help teachers and students take material and do assignments by online. With online learning, teachers are expected to be able to update learning material and students can access it without constraints on place and time, besides assignments to students can be well controlled. In general, all PGRI Foundation schools in Kudus district have the same business process as well as the information system and technology requirements. But in reality, each school develops its architecture and information system separately. On the other hand, the majority of schools do not have enough budget to procure infrastructure to support the information systems needed specifically for learning activities such as e-learning. Cloud computing is often referred to as a new paradigm in the world of information technology related to resource efficiency. Cloud Computing has a service layer known as Software as a Service (SaaS). SaaS has several advantages and conveniences offered, including those related to resource efficiency and speed in developing an application. With SaaS, an application can be used at the same time by many tenants, with each tenant still being protected, so that application development costs can be further reduced. This research uses object-oriented system development methods with UML tools. This research aims to help schools in the Kudus Regency PGRI foundation improve the quality of learning by utilizing e-learning media without the need to think about the process of procurement, installation and configuration of hardware or software.

Generating Use Case Models from Arabic User Requirements in a Semiautomated Approach Using a Natural Language Processing Tool

AbstractAutomated software engineering has attracted a large amount of research efforts. The use of object-oriented methods for software systems development has made it necessary to develop approaches that automate the construction of different Unified Modeling Language (UML) models in a semiautomated approach from textual user requirements. UML use case models represent an essential artifact that provides a perspective of the system under analysis or development. The development of such use case models is very crucial in an object-oriented development method. The main principles used in obtaining these models are described. A natural language processing tool is used to parse different statements of the user requirements written in Arabic to obtain lists of nouns, noun phrases, verbs, verb phrases, etc., that aid in finding potential actors and use cases. A set of steps that represent our approach for constructing a use case model are presented. Finally, the proposed approach is validated using an experiment involving a group of graduate students who are familiar with use case modeling.

The Concept of Object and its Relation to Human Thinking: Some Misunderstandings Concerning the Connection between Object-Orientation and Human Thinking

All throughout the computer science community object-orientation is accepted as being built upon the same basic concepts that human beings use to apprehend reality. This misconcep- tion, as we think, is what we focus on in this paper. To show this we analyse two well-recognised object-oriented systems development methods. We try to pinpoint in what way these methods do not correspond to the way human beings apprehend reality in terms of objects. We show that the methods do not use the concepts of object or class in a manner that corresponds to the way hu- man beings use them to apprehend reality. Furthermore the method-creators do not separate the notion of an object and its representation in a model. We also suggest a better adaptation of the searching-for-objects model based on how human beings apprehend reality. When analysing, one should focus on the purpose of the actions and the two different modes with which an object can be treated: present-at-hand and readiness-to-hand. This will increase the conformity between object- orientation and the way human beings apprehend reality.

데이터 가변성 기반 모바일 자가적응 커스터마이제이션 기법

기존 객체지향 개발 방식과 컴포넌트 개발 방식에서의 재사용성 문제는 모바일 개발에서도 해결해야하는 문제이다. 모바일 어플리케이션에서 기능을 변경하는 것은 모바일 어플리케이션 전체를 업그레이드 할 필요가 있는데, 이는 모바일 어플리케이션이 디바이스 내의 다른 어플리케이션들과 연계된 서비스와의 문제를 발생시킨다. 따라서 모바일 어플리케이션 내에 변경 가능성이 있는 기능들에 대해 재사용성을 고려하여 개발되어야 한다. 본 논문에서는 모바일 어플리케이션이 다양한 요구사항에 대해 재사용성을 높일 수 있는 커스터마이제이션 기법을 제안한다. 가변성 중에 데이터 기반의 가변성을 적용하여 변경을 요구하는 기능에 대해 자동으로 변경될 수 있는 자가적응 커스터마이제이션 기법을 제시한다. The reusability problems in the existing object-oriented development method and component development method is the problem that should be also resolved in the mobile development. Changing the function in mobile applications need to upgrade the entire mobile application, which can cause problems in mobile application in conjunction with other applications within the device. Thus, the changable functions in mobile application should be developed by considering their reusability. In this paper, we propose the customization technique that can be improved reusability for a variety of requirements of mobile application. We propose the self-adaptable customization technique that can change dynamically for the function to require changes by applying the data variability among variabilities.

Traceability-centric model-driven object-oriented engineering

Context Object-oriented (OO) development method is a popular paradigm in developing target systems. However, the current practices of OO analysis and design (OOAD) and implementation largely rely on human developers’ experience and expertise, making it possible less efficient and more error-prone. Hence, there is room for improving the development efficiency while preserving high quality of programs. Objective Model-driven development (MDD) is a promising approach to developing programs by machine-assisted model transformation, saving human efforts and reducing the possibility of introducing program faults. Hence, it is appealing to apply key disciplines of MDD in developing OO programs. Method In this paper, we propose a comprehensive framework for applying MDD on OO program engineering in a rigorous and formal fashion. The framework consists of: (1) a hybrid engineering model of human and machine, (2) meta-models of OOAD artifacts, (3) traceability map with trace links, and (4) transformation rules. Results We identified five platform independent models and two platform specific models, and defined formal representations for them. We identified 16 traceability links and accordingly 16 transformation rules among the eight artifacts. Through the case study, we showed that our work is feasible and applicable. We assessed our work and concluded that our work is sound, complete, and extendable. Our work established the foundation toward automatic generation of OO programs based on the traceability framework. Conclusion It is concluded that it is essential to identify the OOAD artifacts, traceability links, and transformation rules for automatic generation of OO programs. It is also important to understand the human involvement nature in MDD and to explicitly treat them in the model transformation.

An object-oriented development method for Customer Knowledge Management Information Systems

For the advances of Internet technologies in recent years, electronic commerce (EC) has gained many attentions as a major theme for enterprises to keep their competitiveness. Among all possible endeavors for the EC, research has shown that effective management of customer relationships by taking advantage of customer knowledges is a major source for keeping competitive differentiation. Therefore, it is commonly recognized as an important goal for an enterprise to promote its managerial effectiveness on customer relationships through a prospective customer knowledge-based information system to achieve the so-called Customer-Oriented EC. In this paper, we present an object-oriented method for the development of such a Customer Knowledge Management Information System (CKMIS). The method starts from the identification of customers and their desired knowledge-accessed behaviors, through the recognition of a system architecture that supports the identification and realization of these behaviors, and finally ends with the analysis and design of the architectural classes/objects that collaborate to identify and realize these behaviors. The method is use case driven with UML notations utilized and extended as its modeling tool. To illustrate, the method is applied to an exemplified CKMIS for a book publishing company.

Object-oriented development of the embedded system based on Petri-nets

Embedded systems are an emerging field that has commanded attention and support from the industrial community. They have been a part of daily life today. However, complex behaviors and a lack of reusability and modularization have been obstacles to the development of successful embedded systems. A typical issue or challenge of embedded system design lies on the synthesis of software and hardware. Currently, a paradigm shift towards object-oriented (OO) techniques has been advocated in hope of increasing the reusability and modularization. In this paper, an object-oriented development method of the embedded system based on Petri-nets is proposed. The concurrent ability of Petri-nets assists the concurrent co-design of embedded systems synchronously. In addition, the paper applies the reachability tree and the generalized label-correcting (GLC) algorithm to analyze and to validate the designed processes in object-oriented Petri-net models. This solution approach is novel in a sense that by combining various operators and comparators, different types of developing problems in embedded systems can be solved with one algorithm for different values of the initial node.

HASoC--Towards a New Method for System-on-a-Chip Development

We present a novel method (HASoC) for developing embedded systems that are targeted at system-on-a-chip implementations. The object-oriented development method is based on the experiences of using our existing MOOSE technique and supports a lifecycle that explicitly separates the behavior of a system from its implementation technology. The design process, whichuses a notation based on extensions to UML-RT, begins with the incremental development and validation of an abstract executable model of a system. Subsequently, this model is partitioned into hardware and software sub-systems to create a committed model, which is mapped onto a system platform that defines the implementation environment. The methodology emphasizes the reuse of pre-existing hardware and software platforms to ease the development process. A partial example application is presented in order to illustrate the main concepts in our methodology.

Revolution or Evolution? A Comparison of Object-Oriented and Structured Systems Development Methods

This paper examines the changes engendered when moving from a structured to an object-oriented systems development approach and reconciles the differing views concerning whether this represents an evolutionary or revolutionary change. Author co-citation analysis is used to elucidate the ideational and conceptual relationships between the two approaches. The difference in conceptual distance at the analysis and design level compared to that at the programming level is explained using Henderson's framework for organizational change. The conceptual shift during analysis and design is considered architectural, whereas for programming it is deemed merely incremental. The managerial implications of these findings are discussed and suggestions for improving the likelihood of success in the adoption of object-oriented systems development methods are provided.

Object oriented development method for reconfigurable embedded systems

The authors present a novel method for developing reconfigurable systems targeted at embedded system applications. The paper shows how an existing object oriented design method (MOOSE) has been adapted to include reconfigurable hardware (FPGAs). Previous research on reconfigurable computing has concentrated on the efficient mapping of algorithms to FPGAs. It must be realised that reconfigurable hardware usually forms part of much larger embedded systems, which include other hardware components, memories, and processors executing significant software tasks. The paper represents a significant advance over current embedded system design methods in that it integrates the use of reconfigurable hardware components with a systematic design method for complete systems including both hardware and software. The development techniques are illustrated by a practical example. Although the enhanced methodology is applicable to some reconfigurable computing systems, further work is planned to extend our design technique to exploit the potential benefits of embedded systems which can be dynamically reconfigured at system run-time. The final objective is to produce an object oriented design methodology where system objects can be seamlessly implemented in either software or reconfigurable hardware.

GENERATION OF OBJECT-ORIENTED SOFTWARE PROCESS USING MILESTONES

One of the major problems in object-oriented software projects is the lack of management's ability to comprehend and control the development progress of a project. This is because traditional phases of software development are not appropriate for object-oriented development. The project manager's "road map" is likely to be different with different phases, different milestones, and different checkpoints. This paper proposes a new framework which gives us a guideline for generating software process with relevant milestones for object-oriented development methods. The framework provides algorithms for identifying development phases and baseline products based on relationships among activities and products of the development method. In addition, the framework defines a software process model to manage a development progress in which milestones are established at the end of each phase in order to check the baseline product and establish goals for the following phase. Results of the application of the proposed framework show that the framework can generate a software process customized for well-known object-oriented development methods in a systematic way.
