Building a registered volume database

Both object-oriented and relational database management systems are referred to as DBMS. The web-scale is expanding at an incredible rate, and with it comes an increase in mobile applications, technologies, and social media platforms. The rapid growth of these technologies produces a variety of structured and unstructured data in various forms, each of which has various consequences for data security. Using RDBMS and OODBMS, this study's methodology outlines the development, installation, and management process of multiple and complicated data sets. This study gives a documented study comparing different kinds of data stored in databases by employing two types of database techniques: relational database method and object-oriented database technique. We use a different fingerprint database for the web and mobile devices. This database is also managed using different technologies, such as MySQL, and it accommodates data generated using distinct methods. In addition, this study explores the benefits and advantages of the various databases and determines the ideal database management system for organizations. According to the survey's findings, RDBMS stores data and the relationships between them in tables, but OODBMS stores data in objects, in a manner analogous to Object-Oriented Programming (OOP). According to the study's findings, the primary distinction between relational database management systems (RDBMS) and object-oriented database management systems (OODBMS) is that RDBMS is a Database Management System based on the relational model. In contrast, OODBMS is a Database Management System that facilitates creating and modeling data as objects.

Results and observations gathered while implementing the ANSI T1M1.5 GNM-T1.214 standard within an object-oriented database management system (ODBMS) framework are discussed. The generic network model (GNM) proposes a dynamic network modeling methodology that encompasses a wide spectrum of managed telecommunication network resources. Within the GNM, managed telecommunication resources are modeled from building blocks of lower-level resource elements (logical or physical). The complex relationships between GNM resource elements are described either by specialization/generalization or user/containment; therefore, an ODBMS is well suited for implementation of the GNM as compared to conventional database management systems. The ODBMS framework described also allows the database model to evolve with the GNM. It is demonstrated that a proposed refinement of the GNM into subclasses results in a functional database design that can model a large variety of network resources in accord with a standardized network view. >

We describe the implementation of a version manager on an object-oriented database management system. The version manager supports various version semantics and version derivation graphs. Especially, it supports the version propagation to effectively manage versions of design objects and the efficient storage management for versions. All functionalities of the presented version manager are integrated with an object-oriented database programming language seamlessly. Therefore, designers can simply develop their applications which manipulate design objects.

We present a strategy for the validation of an Object Oriented Database Management System (ODBMS), an off-the-shelf component software, when we deliberately introduced faults and observe its behavior in the presence of these faults. A tool designed for the injection of faults in OO applications, specially Java language systems, was used. This Software Fault Injection tool, Jaca, was developed at UNICAMP and has the ability to inject faults in objects’ attributes and methods. For the experiments we used an ODBMS performance test benchmark, Wisconsin OO7. The experiments were aimed at validating the robustness of the ODBMS component in the presence of errors originated at the application. For that purpose a fault injection strategy was proposed to help answer the questions: Where to inject? What error model to use? This strategy was applied, so some results and their analysis are presented. Improvement for Jaca were addressed as a experiments’ result.

Ripple down rules (RDR) is an incremental knowledge acquisition (KA) methodology, where a knowledge base (KB) is constructed as a collection of rules with exceptions. Nested ripple down rules (NRDR) is an extension of this methodology which allows the expert to enter her/his own domain concepts and later refine these concepts hierarchically. In this paper we show similarities between incremental knowledge acquisition and database schema evolution, and propose to use the F2 object-oriented database management system (OODBMS) to implement an NRDR knowledge based system. We use the existing non-standard features of F2 and show how multiple instantiation and object migration (known as multiobjects feature in F2), and schema evolution capabilities in F2 easily accommodate all the update mechanisms required to incrementally build an NRDR KB. We illustrate our approach with a KA session.

An object-oriented anthropometric database for developing a man model

In several working environments, production involves repeated executions of certain procedures. A workflow describes the individual tasks performed in these procedures and their interrelationships. Current workflow management systems (WFMSs) use a database management system (DBMS) to store task descriptions, and implement all workflow functionality in modules that run on top of the DBMS. Motivated by scientific workflows, we propose a much more DBMS-centric architecture, in which conventional database technology provides much of the desired scientific WFMS functionality. A key element of our approach is viewing the workflow as a web of data objects interconnected with active links that carry process descriptions. The workflow is fully defined as a database schema, and its execution is the gradual buildup of an instance of this schema through the active object links. For our work, we use the modeling and querying tools of Horse, the object-oriented DBMS that we have developed in the context of the Zoo Desktop Experiment Management Environment.

In this paper, we have described an accurate and efficient shadowing recognition method based on octree data structure for efficiently judging the illuminated regions in electrically large objects. The physical optics method is used to calculate a bistatic RCS curve for target VFY-218. The theory of shadowing recognition is a hybrid method consists of traditional method and the octree data structure. This novel method is able to analyze the shadowing relationship precisely with less calculation time when compared with traditional method. Finally, numerical experiments and results show the accuracy and efficiency of this method.

Object-oriented technology is an emerging information technology. Object-oriented database technology represents a breakthrough from the dominant relational model. Lacking the similar popularity and acceptance of SQL, object-oriented database management systems, however, are going through a difficult period of standardization. Due the complexity of object-oriented technology and the sophistication of distributed (Internet) computing, object database systems need an efficient and effective way to tackle the issue of heterogeneity and incompatibility. In this paper, we propose a syntax-based gateway model to bridge two key object standards of SQL3 and ODMU. The gateway model is methodological and systematic. The basic belief is that a real representation of the real world has to be discovered to resolve the middleware issue. In this method, we employ a set of general and generic components and constructs that compose a real world object system. We use the set to compare and contrast the composition of SQL3 and ODMG. We devise a limited set of conversion rules to convert the compositions one at a time. A transformation model is built. This approach is traceable and reversible because it is based on analysis design constructs. We have implemented the gateway model. The prototype is composed of an analyzing module, lexical scanner, and grammar parser.

XML is increasingly gaining acceptance as a medium for exchanging data between applications. Given its text-based structure, XML can easily be distributed across any type of communication channel, including the Internet. This article provides an overview of an efficient way to store XML data inside an object-oriented database management system (OODBMS). It first discusses the difference between XML data and XML documents, and then introduces an approach to integrate XML data into the Java/sup TM/ programming language and programming model. This integration is combined with the transparent persistence of Java objects defined by the ODMG.

For the last few years, the middleware industry, and particularly the CORBA project, have strongly integrated several aspects issued from databases: persistence, transaction management, security, etc. However, most object-oriented database management systems (OODBMS) and CORBA middleware have not integrated an essential component: the notion of views which allows various users to see and manage data from different viewpoints. Views provide a semantic structuring of a schema of classes. A lot of application domains are interested in this feature; data mining is a well-known example. The paper focuses on CORBA and proposes a complete software architecture in order to provide an efficient view mechanism for this middleware. This new software architecture provides solutions about evolution problems of available data. We experienced an original use of the IDL language and the IDL compiler which consists of defining for each client (view) a subset of the global server IDL description.

This paper describes our research toward the development a knowledge-based multimedia database system for bone age research. The prototype system is designed to allow users to query for information based on patient demographic profile, patient medical history, evolution constraints of the developing hand, image content, and fuzzy high-level terms and concepts. The major highlights of this work include: 1) object-oriented database management system, 2) graphical user interface for query formulation, 3) object-oriented data model which supports both traditional “Where-type” predicates and new object evolutionary and temporal predicates, and 4) cooperative query answering capabilities for intelligent query modification in the event of a null solution to the original query.

We present an architecture and techniques to manage the TDX-10 switching system based on the ITU-T TMN management model. We extend OSIMIS network management platform to implement generic TMN applications. The hierarchical fault management services/functions are implemented, incorporating the logical layered architecture concept of the TMN management model. The various components of the TDX-10 system are specified using a hybrid MIB modelling approach. The persistent MIB is realized using the UNISQL/M object-oriented database management system. In order to monitor and control the various components of the TDX-10 exchange, the external real resource access system has been built for the OSIMIS agent and TDX-10 system, which include the real resource access communication interface, database access interface, MIB loader and translator.

Data replication is a key issue in a Data Grid and can be managed in different ways and at different levels of granularity: for example, at the file level or object level. In the High Energy Physics community, Data Grids are being developed to support the distributed analysis of experimental data. We have produced a prototype data replication tool, the Grid Data Mirroring Package (GDMP) that is in production use in one physics experiment, with middleware provided by the Globus Toolkit used for authentication, data movement, and other purposes. We present here a new, enhanced GDMP architecture and prototype implementation that uses Globus Data Grid tools for efficient file replication. We also explain how this architecture can address object replication issues in an object-oriented database management system. File transfer over wide-area networks requires specific performance tuning in order to gain optimal data transfer rates. We present performance results obtained with GridFTP, an enhanced version of FTP, and discuss tuning parameters.
