Object Relational Mapping For Enterprise Application Architecture, Musafare Machisa
Object Relational Mapping For Enterprise Application Architecture, Musafare Machisa
Regis University Student Publications (comprehensive collection)
This project investigates the patterns/techniques used and issues that are encountered in developing object-oriented (OO) to relational data mappings for enterprise application architectures. The research will identify the different techniques of object relational data mapping as documented by Martin Fowler in "Patterns of Enterprise Application Architecture" (text for MSCS 630). A prototype implementation will be developed using the techniques found in this research. The goal of the project is to analyze and understand Martin Fowler's patterns and other object relational mapping patterns used in industry and to recommend a set of "best practices".
A Graphical Query Language For Object Oriented Databases, Ramiji Vandara
A Graphical Query Language For Object Oriented Databases, Ramiji Vandara
Electronic Dissertations and Theses
Object Oriented Database Management Systems(OOBMS)became popular in the mid-eighties, as a result of the sharply increased popularity of the object oriented programming languages. Many query languages for a number of OODB systems have been proposed, but most of them are similar, in spirit to SQL, which was designed for a relational database model. In an effort to emulate SQL functionality most of the new languages fail to exploit the fact that data in database is arranged intuitively in an OODB. The need for a more intuitive organization of data increased in recent years with the advent of more complex and …
Using A Distributed Object-Oriented Database Management System In Support Of A High-Speed Network Intrusion Detection System Data Repository, Phillip W. Polk
Using A Distributed Object-Oriented Database Management System In Support Of A High-Speed Network Intrusion Detection System Data Repository, Phillip W. Polk
Theses and Dissertations
The Air Force has multiple initiatives to develop data repositories for high-speed network intrusion detection systems (IDS). All of the developed systems utilize a relational database management system (RDBMS) as the primary data storage mechanism. The purpose of this thesis is to replace the RDBMS in one such system developed by AFRL, the Automated Intrusion Detection Environment (AIDE), with a distributed object-oriented database management system (DOODBMS) and observe a number of areas: its performance against the RDBMS in terms of IDS event insertion and retrieval, the distributed aspects of the new system, and the resulting object-oriented architecture. The resulting system, …
Extensible Multi-Agent System For Heterogeneous Database Association Rule Mining And Unification, Christopher G. Marks
Extensible Multi-Agent System For Heterogeneous Database Association Rule Mining And Unification, Christopher G. Marks
Theses and Dissertations
The Probabilities, Expert System, Knowledge, and Inference (PESKI) System uses the data mining of association rules to fill incompleteness in the knowledge of an expert system. The rules are mined from transactional data sources and then incorporated using an existing link to PESKI. One method of providing a system that will easily allow new data sources to be added is using an information gathering agent-based system. This research first develops a methodology for designing and creating a multi-agent system. It then applies this methodology to design a platform independent means of data mining data sources of any format. The use …
Net-Centric Design And Analysis Of Information Systems, Timothy R. Schmoyer
Net-Centric Design And Analysis Of Information Systems, Timothy R. Schmoyer
Theses and Dissertations
This thesis presents a unique methodology merging state of the art Internet and distributed database technology to support distributed simulations with programming language and platform independence. Standardized models of Command, Control, Communications, Computers, and Intelligence (C4I) systems using Integrated Definition (IDEF) models and executable simulation objects are placed in database repositories which can be accessed and implemented over a distributed simulation network using the Common Object Request Broker Architecture (CORBA). The CORBA distributed simulation network accesses heterogeneous distributed databases, performs distributed processes, and supports portability and reuse of simulation objects and interoperability across operating systems and programming languages.
A Methodology For Reengineering Relational Databases To An Object-Oriented Database, Pedro A. Linhares Lima
A Methodology For Reengineering Relational Databases To An Object-Oriented Database, Pedro A. Linhares Lima
Theses and Dissertations
This research proposes and evaluates a methodology for reengineering a relational database to an object-oriented database. We applied this methodology to reengineering the Air Force Institute of Technology Student Information System (AFITSIS) as our test case. With this test case, we could verify the applicability of the proposed methodology, especially because AFITSIS comes from an old version of Oracle RDBMS. We had the opportunity to implement part of the object model using an object-oriented database, and we present some peculiarities encountered during this implementation. The most important result of this research is that it demonstrated that the proposed methodology can …
Designing And Implementing An Ada Language Binding Specification For Odmg-93, Stephen R. Lindsay
Designing And Implementing An Ada Language Binding Specification For Odmg-93, Stephen R. Lindsay
Theses and Dissertations
Object-oriented database management systems (ODBMSs) represent the latest advancement in database technology, combining the reusability and maintainability of the object-oriented programming paradigm with the ability to efficiently store and retrieve a wide range of data types as well as code to manipulate stored data. Unfortunately, programmers developing software in the Ada programming language do not have the ability to interface to object databases without significant customized code development. One important reason for this has been the absence of a standard defining the constructs accessing ODBMS functionality. This thesis documents the creation of an Ada language binding to the ODMG-93 standard …
Using Object-Oriented Database Technology To Develop A Multiple Domain Capability For Domain-Oriented Application Composition Systems, Alfred W. Harris Jr.
Using Object-Oriented Database Technology To Develop A Multiple Domain Capability For Domain-Oriented Application Composition Systems, Alfred W. Harris Jr.
Theses and Dissertations
This thesis describes the design and implementation of a multiple domain capability for a domain-oriented application composition system, named Architect. The research goal was to show how object-oriented database management system (OODBMS) technology can be used to provide simultaneous access to multiple domain-oriented knowledge bases. Since the Architect system was originally designed using the object-oriented paradigm, insertion of OODBMS technology was relatively simple and many of the object-oriented concepts, such as inheritance and aggregation, proved beneficial. Inheritance was used to encapsulate domain knowledge by defining each domain as a subclass of Architect's software architecture. Aggregation was used to allow applications …
A Format For Storing And Managing Multiple Level Of Detail Terrain For Simulated Environments, Keith L. Meissner
A Format For Storing And Managing Multiple Level Of Detail Terrain For Simulated Environments, Keith L. Meissner
Theses and Dissertations
This study investigated a method of storing, managing and rendering terrain data, while addressing conflicting goals of. rendering speed, display detail and memory usage. A data structure is presented to store terrain data, with an object oriented system to manage the data stored in the structure. The structure stores terrain data in a compact form which is converted into rendering structures in real time. The structure uses levels of detail to maintain display detail. The structure is compared against an existing format for storing terrain data, MultiGen Flight. The system managing the structure is shown to decrease memory usage and …
Translation Of Semantic Aspects Of Oodini Graphical Representation To Onto Oodb Data Definition Language, Xiaoyong Wang
Translation Of Semantic Aspects Of Oodini Graphical Representation To Onto Oodb Data Definition Language, Xiaoyong Wang
Theses
In this thesis we present a system to translate the semantic elements in the graphical schema language of OODINI from API of OODAL to the Type definition of ONTOS DB. To translate semantic constraints of the graphical language, we patch more information to existent class data structure in API of OODAL. After a brief review of OODINI, ONTOS DB and the existent translator without the ability to translate semantic constraints, we describe in detail the methods to translate the essential relationship. dependent relationship, multi-valued essential relationship and multi-valued dependent relationship. We employ an Inverse Reference to a "Set of" Type …

The AFIT Simulation benchmark was designed, implemented, and run on the ObjectStore database …
Using Database Technology To Support Domain-Oriented Application Composition Systems, Danny A. Cecil, Joseph A. Fullenkamp
Using Database Technology To Support Domain-Oriented Application Composition Systems, Danny A. Cecil, Joseph A. Fullenkamp
Theses and Dissertations
This research designed and prototyped an OODBMS technology base to store and retrieve various types of domain artifacts for domain-oriented application composition systems (DOACS). We developed object-oriented database schemas for a validating domain and the Object-Connection-Update software architecture. We implemented an inheritance relationship between the schemas so a domain model can inherit an architectural structure from an architecture model allowing us to isolate domain-specific knowledge from architecture-specific knowledge. We also developed a meta-model to formally define domain models in the database. We then developed a set of database methods to transform a domain model into a database schema for storing …
Graphical Deep Knowledge Representation In Vodak/Vml Object-Oriented Database, Jue Wang
Graphical Deep Knowledge Representation In Vodak/Vml Object-Oriented Database, Jue Wang
Theses
Applying Object-oriented concepts to the design of complex graphical interface has received great attention in the database and knowledge representation disciplines. Traditional CAD systems can not support efficient environments for design processes because they store information about all the objects for display purposes but do not store any knowledge for reasoning purposes. They are called "knowledge poor". "Graphical Deep Knowledge" in Artificial Intelligence has been proven successful to represent knowledge about objects for display purposes as well as reasoning purposes. We introduwd the theory of "Graphical Deep Knowledge" into the object-oriented database s stem VML to design a "Knowledge rich" …

Implementation Of An Object-Oriented University Database Using Vodak/Vml Prototype-2/C++, Bheeman Lingan, Madhumathi Tulasiram
Theses
Object-oriented database (OODB) technology has become very popular and successful in recent years. Currently, there are many commercial object-oriented database systems available that are used for developing large and complex real world applications. In addition, there are many research prototypes of object-oriented databases available. In a joint research project of the CIS Dept at NJIT and GMD-IPSI an object-oriented data model called the Dual Model was developed. Using this Dual Model a university environment database schema was designed. This univesity database schema was implemented using the VODAK/VML OODB prototype - 1. The university database was then reimplemented using the C++ …
Graphical Image Persistence And Code Generation For Object Oriented Databases, Subrata Chatterjee
Graphical Image Persistence And Code Generation For Object Oriented Databases, Subrata Chatterjee
Theses
Attached is the detailed description of the design and implementation of graphical image persistence and code generation for object oriented databases. Graphical image persistent is incorporated into a graphics editor called OODINI. OODINI creates and manipulates graphical schemas for object-oriented databases. This graphical image on secondary storage is then translated into an abstract, generic code for dual model databases. This abstract code, DAL can then be converted into different dual model database languages. We provide an example by generating code for the VODAK Data Modeling language. It is also possible to generate a different abstract language code, OODAL from a …
