Comparison of RDBMS, OODBMS and ORDBMS

The presentation of the similarities and differences between relational modeling of data and the object oriented modeling of data is of great importance both for data base designers and for users. By being well acquainted with the relational model and by noting the similarities and differences between the two approaches to data modeling, designers will be able to turn into account and to make use of the already acquired experience as an important basis for understanding and learning the methodology of designing object oriented databases. At the time if designers know the similarities and differences between these two approaches they have the possibility to convert a relational model into an object oriented model and inverselyRDBMS, OODBMS and ORDBMS comparatively

Object-oriented Programming Laws for Annotated Java Programs

Object-oriented programming laws have been proposed in the context of languages that are not combined with a behavioral interface specification language (BISL). The strong dependence between source-code and interface specifications may cause a number of difficulties when transforming programs. In this paper we introduce a set of programming laws for object-oriented languages like Java combined with the Java Modeling Language (JML). The set of laws deals with object-oriented features taking into account their specifications. Some laws deal only with features of the specification language. These laws constitute a set of small transformations for the development of more elaborate ones like refactorings

An Object Oriented Approach for Business Process Reengineering

Successful Business Process Reengineering (BPR) projects depend on the appropriate business process modeling techniques. On the other side, Information technology (IT) is considered as a key enabler of BPR. Since the object-oriented technique became the most common approach for implementing information systems, the object oriented approach to business process modeling seems to be the best way for more successful BPR projects. This work aims to develop a modeling method for BPR. This method should fill the gap between modeling business process and creating a supportive information system for the redesigned processes in BPR. The present work introduces BPR modeling method that links object orientation with business process modeling. The proposed method integrates an object-oriented modeling method (An Extended object-oriented modeling method) with object-oriented modeling language (Unified Modeling language UML). Design science methodology was used to develop the proposed modeling method. The proposed method was implemented into two types of business process case studies. The implementation showed a promising modeling technique for representing the business process and linking business process modeling with the development of the supportive information system

Proposal for an Object Oriented Process Modeling Language

Processes are very important for the success within many business fields. They define the proper application of methods, technologies and company structures in order to reach business goals. Not only manufacturing processes have to be defined from the start point to their end, also other processes like product development processes need a proper description to gain success. For example in automotive industries complex product development processes are necessary and defined prior to product development. Over the last decades several product modeling languages have been developed moving to object oriented modeling languages, such as UML, but the used process modeling languages are still procedural. The paradigm shift caused by object oriented description within product modeling languages has to be transferred to process modeling languages. This paper introduces an object oriented approach for process modeling. Using UML as a starting point an object oriented process modeling method is differentiated. The basic concepts which are needed for process modeling are put into an object oriented context and are explained. The paper also deals with the most important methods behind object oriented process modeling and gives an outlook, what can be achieved by this approach

High-Order Object Model Based Software Analysis

The integration of object oriented modeling and structured analysis (SA) for developing a well structured object oriented software system is a challenge for requirements analysts and software designers. Some of the existing object oriented modeling techniques adopt approaches that are very different from SA, and others have clumsily stayed with SA after a few modifications. Our High Order Object Modeling Technique (HOOMT) however, attempts to strike a mean between both extremes while at the same time provides an effective modeling method. HOOMT consists of two models, the High Order Object Model and the Object Information Flow Model. By using the familiar divide and conquer concept and functional decomposition, our approach also ensures a less stressful migration of SA analysts to object oriented platforms. The paper introduces HOOMT, its concepts, and notations
