Application integration is a strategic activity and a technology set that can enable an organization to run much more efficiently, and thus provide a significant competitive advantage. Today, in the emergence of many new technologies based on Web services, there are still more approaches for application integration each approach having its limitations and opportunities. We have analyzed the lim...

An aspect-oriented design model consists of a set of aspect models and a primary model. Each aspect model describes a feature that crosscuts elements in the primary model. Aspect and primary models are composed to obtain an integrated design view. In this paper we describe a composition approach that utilizes a composition algorithm and composition directives. Composition directives are used wh...

In this paper, we describe an integrated document management system based on the object-oriented database system OMS. The underlying idea is to replace the current vision of a le system with that of a document database system, thereby ooering higher-level user support for the management of all forms of computer-stored information and work activities. The object-oriented database system provides...

Many issues exist in the communities based on Product Data Management. To address and solve the issues, many applications are being developed and applied. One importnat and quite useful application develops from the Artificial Intelligence. In this research paper we address the importance of Product Data Management (PDM) with respect to the industrial contributional point of view. Moreover we a...

This paper adopts the economic organization framework to the study of industrial dynamics in an international context. We formulated the evolution of solar photovoltaic technology in terms of a stage-gated innovation cycle and studied the institutional requirements for the transition across different stages of development. The objective of organization of the industry, taken technology as given...

Web service search is an important problem in service oriented architecture that has attracted widespread attention from academia as well as industry. Web service searching can be performed by various stakeholders, in different situations, using different forms of queries. All those combinations result in radically different ways of implementation. Using a real world web service composition exa...

Choreographies and Contracts are important concepts in Service Oriented Computing. Choreographies are the description of the behaviour of a service system from a global point of view, while contracts are the description of the externally observable message-passing behaviour of a given service. Exploiting some of our previous results about choreography projection and contract refinement, we show...

Web services registries are a cornerstone for the emerging service-oriented architecture and constitute a critical resource for Web services. Based on a case study we systematically illustrate and evaluate current registries and compare different approaches regarding their architectures and data models in the context of two views: the human and machine (service) based views. The human view on W...

Oracle Materialized Views (MVs) are designed for data warehousing and replication. For data warehousing, MVs based on inner/outer equijoins with optional aggregation, can be refreshed on transaction boundaries, on demand, or periodically. Refreshes are optimized for bulk loads and can use a multi-MV scheduler. MVs based on subqueries on remote tables support bidirectional replication. Optimizat...
