In this paper, we employ the view model given by Bertino to propose a new design approach for a secure multi-level object-oriented database system. The central idea is to provide the user with a multi-level view derived from a single-level secure object-oriented database. Hence the database operations performed on the multi-level views are decomposed into a set of operations on the single-level...

Today there are unmistakable signs that database technology is moving from pure relational technology and pure object-oriented technology toward a unified object-oriented and relational (object-relational, for short) database technology. The basis of unifying relations and objects is the view that the relational model is merely a special case of an object-oriented model. The objective of this a...

View integration is an important technique for developing software systems built upon large databases independent which paradigm is used for realizing the database. We analyzed to which extent traditional view integration methods cover all aspects of object-oriented datamodels and found, in particular, that the integration of methods is hardly supported. We present a methodology for integrating...

Object-oriented view mechanisms have received much attention in the literature in recent years, since they provide powerful mechanisms for addressing tasks such as customized tool interfacing to object-oriented databases (OODBs) and interoperability of heterogeneous databases. However, little progress has been made thus far on addressing the topic of view materi-alization in object-oriented dat...

The purpose of this paper is to provide a theoretical framework for Maritime Informatics from a serviceoriented ecosystem view. We propose to go beyond the traditional service provider-user dyad view to provide a richer understanding of Maritime Informatics using a case study. Relying upon the ServiceDominant (S-D) logic framework, this paper presents how this service-oriented ecosystem view he...

The economic relevance of IT risks is increasing due to various operational, technical as well as regulatory reasons. Increasing flexibility of business processes and increasing dependability on IT require continuous risk assessment, challenging current methods for risk management. Extending IT risk management by a business process-oriented view is a promising approach for taking the occurring ...

Since the size and overall complexity of the software system have been increasing, the existing program has to be modularized on the basis of separation of concerns, so aspect oriented programming tries to address the existing program by modularizing the crosscutting functionality into more precise and manageable modules known as aspects. We have proposed a tool Aspect-CAM (Clustering-based Asp...

The consideration of Product information or Knowledge management, product traceability or genealogy, and product life cycle management implies new strategies and approaches to manage flows of information that relate to flows of material managed in shop floor level. Moreover, throughout product lifecycle coordination needs to be established between reality in the physical world (physical view) a...

Multiple dispatching provides increased expressive power over single dispatching by guiding method lookup using the values of all arguments instead of only the receiver. However, existing languages with multiple dispatching do not encourage the dataabstraction-oriented programming style that is encouraged by traditional single-dispatching languages; instead existing multiple-dispatching languag...
