This paper presents the establishment of the information of metadata for an Authorization tool of UML class diagram. When it comes to modeling classes in UML class diagram, the paper defines expressed classes and the relationship. The class represents the concept of an object, which defines Name, Attribute and Operation. The relationship is between classes, which defines the name and the type of the Relationship, From Class and To Class. And it suggests how to handle and process the information of metadata for an authorization tool of UML class diagram.

The UML(Unified Modeling Language) Class Diagram which is a part of structure of UML is fit for Object Modeling, and more recently, as the appearance of UXF(UML eXchange Format) UML Class Diagram by itself, can be exchanged in many other different system document. So this paper suggest the conversion system from UML Class Diagram to XML DTD. As this we can easily transformation and saving the UML Class Diagram that is the standard of Modeling Language to XML document which is so reusable. Also it can give a flexible method for the representation to the logical structure of document in various way because of converting XML DTD.

This study suggested ways to control UML diagram and to make design of database and to retrieve diagram information by giving questions. The study classified elements of the diagram. For instance, class diagram was made of classes, and class was done of class name and attribute operator. The elements were transformed to be database table having basic key and foreign key information. The ways suggested had advantages of users' sharing of model information and reuse of the model. This study investigated cost saving, time saving and UML model construction by database. We had designed integrated and relation database that could save and manage UML diagram, and suggested retrieval. For instance, we classified class diagram into elements to make tables and kept relation of each element by using not only basic key of relation database but also foreign key information. We made database of modeling depending upon methods to give users convenience.

In the systems and software modeling field, a conceptual model involves modeling with concepts to support development and design. An example of a conceptual model is a description developed using the Unified Modeling Language (UML). UML uses a model multiplicity formulation approach, wherein a number of models are used to represent alternative views. By contrast, a model singularity approach uses only a single integrated model. Each of these styles of modeling has its strengths and weaknesses. This paper introduces a partial solution to the issue of multiplicity vs. singularity in modeling by adopting UML use cases and class models into the conceptual thinging machine (TM) model. To apply use cases, we adopt the observation that a use-case diagram is a description that shows the internal structure of the part of the system represented by the use case in addition to being useful to people outside of the system. Additionally, the UML class diagram is recast in TM representation. Accordingly, we develop a TMUML model that embraces the TM specification of the UML class diagram and the internal structure extracted from the UML use case. TMUML modeling introduces some of the advantages that have made UML a popular modeling language to TM modeling. At the same time, this approach supplies UML with partial model singularity. The paper details experimentation with TMUML using examples from the literature. Our results indicate that mixing UML with other models could be a viable approach.

In this paper, we implement the XML and data modeling by the UML tool, in which the class diagram is constructed from the sequence diagram after making the use case diagram. For the XML modeling. the guiding line will be presented to transform the UML class into the XML document, and then an example to draw the XML DTD from the UML class will be also shown. Furthermore, through the proposed data modeling, the integrated design methods for the transformation of the UML class into relational database schema. object-relational database schema and object-oriented database schema also will be proposed. Finally, we will be presented schema for each database system.

A messenger program in this paper was designed and implemented using Use Case Diagram, Class Diagram, Activity Diagram, and Sequence Diagram. We selected total 7 major functionalities such as PC server, login, friends management, chatting, file transfer, account management, etc. The followings are various implementation results from this paper. First, developers could easily understand the desired product and programming flow from using UML Diagrams. Second, PDA users could communicate with developers for a long time without time constraints. Third, there was high usability of UML Diagram in the phase of objected-oriented analysis. Forth, it was easy to update and maintain a program.

This paper suggests the design of MVC model for an authorization tool of UML class diagram. In the design of MVC model, it is designed to define view, controller and model and perform the individual role of each component. The View represents GUI and the Controller is responsible for data input and output and the Model is to handle the business logic. The MVC model design for an authorization tool of class diagram gives the role independently and tries to be flexible with system by dividing into the suitable features of each component.

소프트웨어 산업계에서 재사용 단위가 객체보다 더 큰 컴포넌트 기반의 개발에 관심이 집중되고 있다. 그래서 모델링 언어인 UML과 컴포넌트가 운용되는 유연하고 확장성 높은 기반 아키텍처인 EJB를 이용한 기업형 시스템 개발이 요즘 기업에서 활발해지고 있다. UML과 EJB 각각에 대한 연구는 많이 진행되었지만, UML Model을 이용한 EJB Model 구현시의 mapping 기법에 관한 연구는 아직 미흡한 실정이다. 그래서 본 논문에서는 UML Modeling을 통해 Class diagram에서 추출된 Class들이 EJB로 구현될 때 실제로 어떤 Bean으로 Mapping 되는지에 대해 제시한다.

UML class diagrams are used to visualize the static aspects of a software system and are involved from analysis and design to documentation and testing. Software modeling using class diagrams is essential for software development, but it may be not an easy activity for inexperienced modelers. The modeling productivity could be improved with a dataset of class diagrams which are classified by domain categories. To this end, this paper provides a classification method for a dataset of class diagram images. First, real class diagrams are selected from collected images. Then, class names are extracted from the real class diagram images and the class diagram images are classified according to domain categories. The proposed classification model has achieved 100.00%, 95.59%, 97.74%, and 97.77% in precision, recall, F1-score, and accuracy, respectively. The accuracy scores for the domain categorization are distributed between 81.1% and 95.2%. Although the number of class diagram images in the experiment is not large enough, the experimental results indicate that it is worth considering the proposed approach to class diagram image classification.

This paper presents a technique of contstructing and processing the metadata information, which is for UML class authorization tool. Construction of the information authorization tool defines Classes and Relationship based on the elements of the consisting of UML class diagram. Definition of the information class is a visibility of Class, a name of Class, an attribution of Class and an operation of Class. Definition of the relationship with information is a name of Relationship, a type of Relationship, a FromClass and a ToClass. In this paper, for a class authorization tool, it suggests a technique to save and read information from information Storage based on the constructed information.
