We have developed a method to address the problem of object identification from two different directions: 1) building an object model of the application based on system documentation to ensure the creation of application-semantic classes; and 2) analyzing the source code to identify potential class candidates on the basis of compound data types and data flow analysis. Object model classes are bound to class candidates to prepare a forward biased and thus semantically meaningful program transformation at the source code level. In this paper; we define a similarity measure for classes to enables the binding process. We also describe the constraints and benefits of human intervention in this process. We have applied this method to a real-world embedded software system to identify potential classes; results from the case study are given in the paper.","PeriodicalId":252030,"journal":{"name":"Proceedings.

Componentware or CBSE (Component-Based Software Engineering) is promising to change the way we develop software. A variety of software components are available at different levels of software architecture. To explore the matching of components across the different technology groups, we have conducted a number of experiments in part of the Software CALS NGSE (Next Generation Software Engineering Program) in Japan. We developed a single prototype application with multiple combinations of technologies such as ActiveX-and-CORBA, multiple CORBAs, CORRA-Web and CORBA-and-legacy-code. Major problems we encountered include: 1) different interface models; 2) poor interface information such as behavior information; 3) poor interface-centric design methodology and architecture design methodology; 4) poor non functional information of components.","PeriodicalId":252030,"journal":{"name":"Proceedings.

Hence, the static as well as the dynamic structure of the system has to be represented in a structured way. Graph transformation systems support static and dynamic modeling through a single computational framework for the sake of correctness, maintainability, and integrity. The framework introduced along with the corresponding tool, UPGraDE (Universal Programmed Graph Grammar Development Environment), which is based on the universal graph language GRASP (GRAph grammar with Set Productions). Any type of system can be specified through a minimal set of operations (syntax) and rules to specify the behavior of any type of software (semantics). The UPGraDE Environment, consisting of several totally transparent interconnected modules, performing well defined tasks, is a highly modular and extensible environment suited for nearly every GRASP development purpose.","PeriodicalId":252030,"journal":{"name":"Proceedings.

The effective performance of collaborative work distributed among several locations requires that information be replicated and freely updated in each distributed server. This is difficult to achieve with existing information-sharing methods such as the WWW and workflow. Our optimistic lock control method enables the direct updating of replicated information in any server while maintaining consistency among all the servers. A server failure is not critical to other servers because there is no master server. This method differs from the traditional master-slave method in which updates are performed in a specific master server. This paper also addresses the dynamic deployment of a new server. Our method is being used on a trial basis for an international software development project between Japan and India.","PeriodicalId":252030,"journal":{"name":"Proceedings.

Introducing the representation of business processes in the database schema allows the execution histories of business processes to be maintained in the database for supporting queries on how business processes are executed. In this work, we incorporate finite state machines into the entity-relationship (ER) model for representing business processes in the database schema. Analytical systems can be developed in the proposed representation to assist decision-makers in observing the business processes.","PeriodicalId":252030,"journal":{"name":"Proceedings.

To overcome the challenge, the new trend is to adopt component based software engineering (CBSE). The key difference between CBSE and traditional software engineering is that CBSE views a software system as a set of off-the-shelf components integrated within an appropriate software architecture. CBSE promotes large scale reuse, as it focuses on building software systems by assembling off-the-shelf components rather than implementing the entire system from scratch. CBSE also emphasizes selection and creation of software architectures that allow systems to achieve their quality requirements. As a result, CBSE has introduced fundamental changes in software development and maintenance.","PeriodicalId":252030,"journal":{"name":"Proceedings.
