Debugging on computer program is a complex cognitive activity. Although it is complex, it’s still one of the popular issues in computer programming task. It is a difficult task, which is to understand what the error is and how to solve such error? In computer programming the difficulty is to understand the Object-Oriented programming concept together with the programming logic. If the programming logic is incorrect, the program codes will have such error named as logic error and can caused highly maintenance cost. Logic error is a bug in a program that causes it to operate incorrectly, without terminating or crashing the program. It will produce unintended output or other behavior than what we are expecting. Method that use to develop a propose model Object Oriented Debugger is Unified Modeling Language (UML). It is the best choice model and suitable to design the Object Oriented Debugger which will be developed in an object oriented programming environment. The model will provide an ability to capture the characteristics of a system by using notations in the process of designing and implementing the system. The model of Object Oriented Debugger has been successfully implemented. This model has been developed using Unified Approach methodology, which consists of two methods such as Object-Oriented Analysis (OOA) and Object-Oriented Design (OOD). The model developed is to capture the structure and behavior of the Object Oriented Debugger by using the UML diagram. The model also can ease the readability of the documentation for the maintenance purposes. The design of the Object Oriented Debugger Model has been developed using the UML notation. It’s consisting of two parts that are object-oriented analysis and object-oriented design. All the developing and designing are based on the model in UML.

in particular. Data management for muzaki, acceptance, and distribution and its report has been computerized, but have the disadvantage that is not integrated with one another and still use a computer that will reduce the efficiency of time management plus a few features that are less like making a donation receipt and report.

This article proposes a prototype development of ET (Embedded technology) rescue robot that follows an object-oriented analysis and design methodology (OOADM) by using a UML (Unified modeling language) as a tool in the process. The idea is to improve the robot application development process to be efficient, rapid, and conformable with the standard by using the UML. The ET rescue robot prototype comprises of the two systems; a robot control system and a victim discovering system. The robot operation control is performed by a computer that interconnects the robot via a Bluetooth network. The operator monitors the robot operation by using video, sound, and temperature data that are captured through a camera, sound sensor, and temperature sensor installed on the robot to discover the victim, respectively. The robot was tested and experimented under the environment imitated the victim discovery in disastrous scenario. The result reflected that the prototype of ET rescue robot can be developed in the application level by following the OOADM as specified in the requirements.

Recently, a formal development process of robot in an application level has not been sufficiently encouraged and promoted. This leads an insufficient procedure to improve the robot development process in the application level. This article introduces an object-oriented analysis and design methodology (OOADM) that is applicable to the robot development process, i.e., a field sensing robot, in the application level. The Unified Modeling Language (UML) is used as a tool for analysis and design of the field sensing robot. The Mindstorms Lego model RCX is deployed as the main robot hardware and the C++ programming language is employed as the software tool for implementing the field sensing robot application. The tasks of robot are defined to move across the fields, to avoid the obstacles, and to reach the end point, according to the requirement. The robot employs the light sensor to detect the field surfaces in order to specify different types of movement, i.e., moving on a normal surface, increasing and reducing speed across a slop surface, and moving within a boundary. In addition, the robot uses the touch sensors to detect the obstacles during its movement toward the end point and to dodge the obstacles when hitting them. The robot operation is completed when the end point is detected. By following the formal standard development process using the UML model, the application of robot can be implemented rapidly and efficiently.

In recent years, agent-based systems have received considerable attention in both academia and industry. The agent oriented paradigm can be considered a natural extension to the object oriented (OO) paradigm. In spite of the fact that there are many OO analysis and design methods, there is very little work reported on design and analysis of agent-based systems. Agents differ from objects in many issues which requires special modeling elements. In this paper, we propose a software engineering process for agent-based systems based on existing object-oriented software engineering concepts. We extend the Unified Modeling Language (UML) to model agents (static and mobile).

The main purpose of this paper is to present knowledge-based Enterprise model (EM) sufficiency as data repository for Unified Modelling Language (UML) models generation. UML models are one of the most usable modelling languages in system lifecycle design stage, despite the problem domain of the system. UML models can be generated from Enterprise Model by using particular transformation algorithms presented in previous researches. Generation process from Enterprise model is represented by certain Hospital Information Management process example. Generated UML dynamic Use Case, Activity, Sequence and State models of different perspectives of Hospital Information Management process prove sufficiency of stored information in Enterprise model.

The Unified Modeling Language (UML) is becoming widely used for software and database modeling, and has been accepted by the Object Management Group as a standard language for object-oriented analysis and design. For data modeling purposes, UML includes class diagrams, that may be annotated with expressions in a textual constraint language. Although facilitating the transition to object-oriented code, UML’s implementation concerns render it less suitable for developing and validating a conceptual model with domain experts. This defect can be remedied by using a fact-oriented approach for the conceptual modeling, from which UML class diagrams may be derived. Object-Role Modeling (ORM) is currently the most popular fact-oriented approach to data modeling. This paper examines the relative strengths and weaknesses of ORM and UML for data modeling, and indicates how models in one notation can be translated into the other.Request access from your librarian to read this article's full text.

The unified modeling language (UML) is one of the most commonly used modeling languages in the software industry. It simplifies the complex process of design by providing a set of graphical notations, which helps express the objectoriented analysis and design of software projects. Although UML is applicable to different types of systems, domains, methods, and processes, it cannot express certain problem domain needs. Therefore, many extensions to UML have been proposed. In this paper, we propose a framework for integrating the UML extensions and then use the framework to propose an integrated unified modeling language-graphical (iUML-g) form. iUML-g integrates the existing UML extensions into one integrated form. This includes an integrated diagram for UML class, sequence, and use case diagrams. The proposed approach is evaluated using a case study. The proposed iUML-g is capable of modeling systems that use different domains.

To ease the development of distributed systems, the visual notions for the structural aspects of object-oriented analysis and design should be combined with techniques for handling concurrency and distribution. A novel approach and language for the visual design of distributed software systems is introduced and illustrated by means of an example. The language of OCoNs (Object Coordination Nets) is integrated into the structuring mechanisms of the UML (Unified Modeling Language) standard for object-oriented analysis and design. Such an object-oriented notation is crucial for handling complex software systems and can be extended with the graphical expressive power of Petri nets to also describe concurrency and coordination. The same visual language is used to specify the interfaces and contracts of software components, the resource handling within a component as well as the control flow of services.

Unified Modeling Language (UML) has emerged as the software industry’s dominant modeling language. It is the de facto modeling language standard for specifying, visualizing, constructing, and documenting the components of software systems. Despite its prominence and status as the standard modeling language, UML has its critics. Opponents argue that it is complex and difficult to learn. Some question the rationale of having nine diagramming techniques in UML and the raison d’être of those nine techniques in UML. Others point out that UML lacks a comprehensive methodology to guide its users, which makes the language even more convoluted. A few studies on UML can be found in the literature. However, no study exists to provide a quantitative measure of UML complexity or to compare UML with other object-oriented techniques. In this research, we evaluate the complexity of UML using complexity metrics. The objective is to provide a reliable and accurate quantitative measure of UML complexity. A comparison of the complexity metrical values of UML with other object-oriented techniques was also carried out. Our findings suggest that each diagram in UML is not distinctly more complex than techniques in other modeling methods. But as a whole, UML is very complex–2-11 times more complex than other modeling methods.

The Web Services Choreography Description Language (WS-CDL) is a specification developed by the W3C and can be viewed as a blueprint for the development of end-point services. Consequently, it is worth providing a systematic approach for its modeling, analysis and verification. The Unified Modeling Language (UML) is an industry standard for modeling. Applying UML to model WS-CDL is obviously a promising solution to bring together academics and practitioners through a unique standard language. In this paper, we propose to use different UML diagrams to model WS-CDL. UML Component Diagram is used to model the underlying structure of WS-CDL. UML Sequence Diagram is utilized to model the activities in WS-CDL. UML State Machine Diagram is utilized to model the behaviors of each role participating in a WS-CDL specification. We then enrich the UML State Machine Diagram with data by the use of UML Class Diagram. Given the UML specification of WS-CDL, we then provide a systematic way of formally analyzing and verifying WS-CDL against desired properties. Some experiments show that our approach can verify structural, behavioral and data properties in a middle-scale data-enriched WS-CDL specification.

In this chapter, we provide the essential theory and practical details of employing the principles of Object Orientation (OO) in system architecture modeling. We do not attempt to provide an exhaustive OO tutorial, since there exists a very large literature on this subject (see the references to this chapter). Our goal, instead, is to give the reader the level of understanding needed to master the MBSAP methodology and apply it to practical system architecting challenges. First, we present the rationale for OO and define the essential concepts and terminology, stressing the benefits it delivers in dealing with complex entities. Although we use the Systems Modeling Language (SysML) as the basis for this book, we begin by discussing and illustrating the primary diagrams of the Unified Modeling Language (UML), which is the root language standard for OO. This is then followed by a description of the changes to UML introduced by the SysML, which is defined as a Profile of UML. The reality is that a large part of the SysML is taken directly from the UML language specification. We believe understanding of this material is enhanced by first considering the parent UML and then explicitly showing how UML modifies and extends the language. We include generic UML and SysML diagrams that illustrate important principles and syntax and that can serve as format samples in developing real architecture models. Appendices A and B are concise references to UML and SysML, respectively, intended to give readers a quick and easy way to look up the details. Chapter objective: the reader will be able to create and read UML and SysML diagrams and to describe the role of each.
