A natural language query interface for databases provides the user friendliness in retrieving the desired information by querying in a native natural language. Up to now, many natural language query interfaces for conventional databases have been developed. However, the eld of natural language query interfaces for object-oriented databases which have recently started to emerge as the next-gener...

Smartphones are becoming increasingly ubiquitous both in general society and the workplace. Recent increases in mobile processing power have shown the current generation of smartphones has equivalent processing power to a supercomputer from the early 1990s. Many industries have abandoned desktop computing and are now entirely reliant on mobile devices. Given these facts it is logical that smart...

The demand for efficient software system is increasing day by day. Maintainability is considered as an important quality factor for developing the efficient software system. Recent trends show that mostly software systems are using object-oriented technique to develop the quality software products. Object-oriented approach enhances the maintainability of software system. In literature there are...

Background: Temporomandibular joint disorder (TMD) might be manifested as structural changes in bone through modification, adaptation or direct destruction. We propose to use Local Binary Pattern (LBP) characteristics and histogram-oriented gradients on the recorded images as a diagnostic tool in TMD assessment.Material and Methods: CBCT images of 66 patients (132 joints) with TMD and 66 normal...

This paper presents a new method for image retrieval using a graph object oriented database for processing the information extracted from the image through the segmentation process and through the semantic interpretation of this information. The object oriented database schema is structured as a classes hierarchy based on graph data structure. A graph structure is used in all phases of the imag...

A join index hierarchy method is proposed to handle the “goto’s on disk” problem in objectoriented query processing. The method constructs a hierarchy of join indices and transforms a sequence of pointer chasing operations into a simple search in an appropriate join index file, and thus accelerates navigation in object-oriented databases. The method extends the join index structure studied in r...

CEP and Databases share some characteristics but traditionally are treated as two separate worlds, one oriented towards real-time event processing and the later oriented towards long-term data management. However many real-time data and business intelligence analysis do need to confront streaming data with long-term stored one. For instance, how do current power consumption and power grid distr...

Nowadays, a major paradigm of large scale distributed processing is service-oriented computing (or SOA, Service Oriented Architecture). To improve availability and reliability of SOA based systems and applications, a Reliability Service (providing external support of web services recovery) is proposed.

This paper describes the active, object-oriented database system SAMOS being developed as a research prototype. Its main approach is the integration of rules in the sense of active database systems into a general object-oriented data model. Our effort is also focussed on integrating the rule system with transaction processing in a meaningful way.

Service-oriented architectures expose new chances and challenges for privacy and data protection. The potentially increased distribution of personal information across multiple domains make subject access requests difficult to handle. Which service did process what data? Whom to address for liability issues? At the same time, the service orientation offers a new approach for the granularity of ...
