Certainly, the success of the Unified Modeling Language (UML) as the de facto standard for modeling software systems does not imply closing the door on scientific exploration or experimentation with modeling in the field. Continuing studies in this area can produce theoretical results that strengthen UML as the leading modeling language. Recently, a new modeling technique has been proposed called thinging machine (TM) modeling. This paper utilizes TM to further understand UML, with two objectives: (a) Fine issues in UML are studied, including theoretical notions such as events, objects, actions, activities, etc. Specifically, TM can be used to solve problems related to internal cross-diagram integration. (b) TM applies a different method of conceptualization, including building a model on one-category ontology in contrast to the object-oriented paradigm. The long-term objective of this study is to explore the possibility of TM complementing certain aspects in the UML methodology to develop and design software systems. Accordingly, we alternate between UML and TM modeling. A sample UML model is redesigned in TM, and then UML diagrams are extracted from TM. The results clarify many notions in both models. Particularly, the TM behavioral specification seems to be applicable in UML.

Software development methods have continued to evolve in response to changes in the environment. Structural methodology, information engineering methodology, and object-oriented methodology are the major trends of this change. Each methodology has its own characteristics and advantages, and its applied fields are different. Engineers performing practical work are familiar with applying each methodology, but are not familiar with applying structural methodologies or information engineering methodologies in an integrated manner. Therefore, the maximum effect of the methodology cannot be obtained. With this in mind, we would like to organize and present examples of how to integrate and apply structural methodology and information engineering methodology to the target of each methodology.

One of the important applications in Enterprise Resource Planning(ERP) systems is the Manufacturing Resource Planning(MRPII) system using Bill of Material(BOM). The manufacturing resource planning determines the quantity and timing of the production or purchase of subassemblies and raw materials needed to support the Master Production Scheduling(MPS). The bill of material is the recipe, a list of the materials needed to make a product. This paper intends to suggest a component-based materials management system using Unified Modeling Language(UML), as an application system for automobile part industry. Applying component based materials management systems designed with UML methodology, we analyzed the workflow and the document on materials management process from production planning to inventory management, and implemented a prototype of efficient materials management system, as a surrogate of existing material requirement planning(MRPI) system. To produce many other assemblies for a automobile part firm, component parts are assembled into subassemblies that are joined to assemble the finished product. Through the system suggested in this study, the level of inventory has cut down and the cost of inventory management has decreased. Also, the development method using UML makes the analysis and design phase to shorten in implementation period of MRPII system. The implementation of materials management system using CBD shows the ease of use in software reuse and the interoperability with corporate Internal information system. The result of applying object-oriented CBD technique is to minimize the risk of life cycle and facilitate the reuse of software as mentioned to limitation of information engineering methodology.

In searching and locating a collection of components on the Web, users require a Web browser. Since the Web libraries tend to grow rapidly, there needs to be an effective way to organize and manage such large libraries. Traditional Web-based library(retrieval) systems provide various classification scheme and retrieval services to store and retrieve components. However, these systems do not include invaluable services, for example, enabling users to grasp the overall contents of the library at the beginning of retrieval. This paper discusses a Web-based library system, which provides the efficient management of object-oriented components and a set of services beyond simple component store and retrieval. These services consist of component comprehension through a reverse engineering process, automated summary extraction, and comprehension-based retrieval. Also, The performance of an automated cluster-based classification scheme adopted on the system is evaluated and compared with the cluster-based classification scheme adopted on the system is evaluated and compared with the performance of two other systems using traditional classification scheme.

In this paper, a mobile banking system which can provide banking services is introduced. Since a PDA has excellent features like a small-size computer and provides mobility, it has been widely used by salesmen. Therefore, if general banking services can be provided with PDA by using wireless technology, it will be very useful. In addition, it is easy to develop and maintain the client software of PDA because it uses Windows-based operation systems. In this paper, a PDA banking system is introduced. The system is designed and developed based on the techniques of wireless network, security and PDA programming to be used for mobile banking and a prototype system is developed. Moreover, we used the object-oriented modeling technique, UML and Java Beans for programming.

객체 지향 소프트웨어의 확장과 더불어 소프트웨어의 재사용성의 중요도가 부각되면서 소프트웨어를 콤포넌트 단위로 구현하는 추세이다. 따라서 콤포넌트 기반의 소프트웨어 개발에서의 통합 테스트가 중요한 이슈로 떠오르고 있다. 그러나 콤포넌트들의 통합 테스트에 대한 연구는 미흡한 상태이다. 본 논문에서는 UML을 기반으로 체계적인 통합 테스트 모형을 제안하고. 나아가 본 논문에서는 "멀티미디어 정보처리 시스템"의 사례를 본 논문의 콤포넌트 통합 테스트 모형에 적용한 결과를 분석하여 기술한다. 콤포넌트 통합 테스트 모형은 UML(Unified Modeling Language)의 순서도(sequence diagram)와 협력도(collaboration diagram)를 이용하여 전체 시스템에서 UML의 사건흐름을 구성하는 콤포넌트들 사이의 인터페이스 영역에 존재하는 오류들을 추출한다. 그리고 UML을 기반으로 통합 테스트를 수행함으로써, 테스트 준비 작업을 줄이고, 기존의 UML 지원 도구들과 연계하여 테스트 자동화 도구의 구현을 앞당길 수 있다. 또한 시스템의 순차적 흐름 뿐 아니라, 동시에 수행되는 흐름에 대한 정보까지 모두 수용하여 테스트함으로써, 콤포넌트 기반의 분산 환경의 특성에 적합하다. Abstract As the object-oriented approach to software development becomes more mature, software development from pre-existing, independently developed components becomes an important aim of software engineering. Therefore, integration testing becomes an important aspect of component-based software development. However, there has been little work done in the area of the component-based integration testing. In this paper, we propose the "component integration test model" which is based on UML. Furthermore, we describe a case study on "Multimedia Information Processing System" conducted to analyse the result from which our model is applied. Our model extracts the faults, which exist in interfaces of components, using sequence diagram and collaboration diagram of UML(Unified Modeling Language). As our model is based on UML, the preparation effort for testing is reduced and its test-tools can be implemented more easily through linking existing UML tool. And our model accepts the information of concurrent flow represented by collaboration diagram as well as sequential flow, so it is more suitable to component-based distributed environment.based distributed environment.

The purpose of this study is to provide a quantitative evaluation index of object-oriented software development productivity for EJB 3.0 and EJB 3.1. A lightweight container architecture is a newly-developed architecture in order to solve demerits that N-Tiers enterprise architecture has and to support merits therein. A lightweight container architecture is not as heavy as EJB(Enterprise JavaBeans) architecture is, whereas it provides all the functionality of the EJB container. However, there have been insufficient studies on a performance evaluation of EJB 3.0 and EJB 3.1 on an identical platform. Since a quantitative analysis has been performed only with respect to a partial LoC(Line of Code) analysis, there have been insufficient objective evaluation indeces and guidelines for a new specification released. Accordingly, there has been limited evaluation of software development productivity and on new innovations in a project. Therefore, this study designed and implemented a movie reservation system in EJB 3.0 and EJB 3.1, which was based on the same development platform environment. This study then intends to provide evaluation guidelines for an objective software development productivity cl LoC(Lineand standardization thereof by development platform environment.

Over the past decade, building information modeling (BIM) has gained a foothold in the construction sector. However, as digital data generated in the virtual space of a computer environment, BIM-based data have an inherent limitation in their application efficacy under field conditions. To overcome this, the present study employs augmented reality (AR) to reduce the discrepancy between the digital data generated in virtual spaces and real-world conditions. We assessed the potential applicability of an AR-based interface by analyzing existing examples of Apple, Google, and Facebook, which reflect the recent developments of technologies focusing on user experience. We then proceeded with an AR study, restricting the scope of application to a mobile environment in which an efficient information transmission between a digital model and real life can take place. Object-oriented software engineering was employed to ensure an efficient implementation of a BIM-based AR system for campus space management (CSM) in a mobile environment. Finally, we conducted a module test to check the reliability of the CSM method by using an AR-based mobile system with a prototype of the model used in university campuses, and extracted and itemized the supplementary requirements for CSM by using BIM tools for running AR applications.

The concept of integrated product information has been universalized so that many manufacturing industries have applied the concept to their production system. The field of PDM (Product Data Management), which is one of the core components of the integrated product information, is not an exception. Therefore, various PLM (Product Lifecycle Management) software providers are in process of suggesting the PDM solutions. As the PDM solution is widely adopted in the manufacturing industries, the successful application of the solution has been gathering more strength in manipulation of the product information. However, the standardized implementation methodology is stuck in the basic level contrast with the enhanced PDM's functionality and capability. Present study refers to the application of UML (Unified Modeling Language), which is an object oriented modeling description, to PDM system development procedure. The advantage of UML is its efficiency and effectiveness in handling complex requirement often found in PDM implementation works. This paper shows the integration of PDM and UML proposes a philosophy for the support of requirement analysis throughout the full implementation of PDM system.

Appliciltion systems focusing class units, as component abstraction based on source code, has insufficient benefit of independency and reuse of elements. Only few effects are acquired, because it is only inclined implementation. We need design pattern to represent not only the problem abstraction but also information and relationship between system elements for generic solutions of specific domain Also, it is essential to software reverse engineering to catch the correct system through examming the cxisting system and utilizing the acquired knowledges as reusable resource. Namely, software reverse engineering for extracting the design pattern is very important because it improves the understand ability for system analysis and design through extracting the design structure of object-oriented system, and provides rich and high leIel reusabilitv through grasping the standard idioms and relationships between components. In this paper, we defined the extraction algorithm for design patterns with standardized, packaged and quantitative measlIIul thruugh applying reyerse engineering into existing ubject Olicnted system.
