Performance Measurement Of Three Commercial Object-Oriented Database Management Systems, Timothy J. Halloran
Performance Measurement Of Three Commercial Object-Oriented Database Management Systems, Timothy J. Halloran
Theses and Dissertations
The goal of this thesis was to study the performance of three commercial object-oriented database management systems. The commercial systems studied included Itasca, sold by Itasca Systems Incorporated Matisse, sold by Intellitic International and ObjectStore, sold by Object Design Incorporated. To examine performance of these database management systems two benchmarks were run the OO1 benchmark and a new AFIT Simulation benchmark. The OO1 benchmark was designed, implemented, and run on all three database management systems. ObjectStore was our top performer on all configurations of the OO1 benchmark. 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 …
A Distributed Object-Oriented Database Application Design, Hsin-Feng Edward Wu
A Distributed Object-Oriented Database Application Design, Hsin-Feng Edward Wu
Theses and Dissertations
The purpose of this study is to analyze and develop a distributed object-oriented database management system (DOODBMS) application to support parallel software development of the Parallel Algorithms and Applications Group (PAAG) at AFIT. By following the software lifecycle of object-oriented paradigm, this thesis investigation is intended to generate requirements analysis, design, implementation, user interface design and implementation, and integration of the database application with the user interface. ITASCA, an existing DOODBMS platform, has been chosen to prototype the application for its distribution functionalities and object-oriented modeling power. The user interface of the database application is based on X-window OSF/Motif front-end …
Object-Oriented Database Access From Ada, Li Chou
Object-Oriented Database Access From Ada, Li Chou
Theses and Dissertations
Ada embodies many modern software engineering principles, namely, modifiability, efficiency, reliability, and understandability. Its powerful data abstraction allows programmers to easily model objects in the real world. A database management system (DBMS) provides long term storage. It provides a convenient and efficient environment to manipulate data. Currently, with Ada access to a DBMS is typically done through the use of a language extension and a preprocessor to convert the extensions to library calls appropriate for the DBMS. However, these systems are limited on more complex applications, such as computer-aided engineering design. Object-oriented design (OOD) is a new way of thinking …
