Constraint models for an object-oriented database
There has been much work in the area of object-oriented databases for engineering design applications. The ability to define and have enforced arbitrary semantic constraints to represent design rules and design intent factors is a useful attribute of such an engineering design database. There are a …

Supporting Local Autonomy in a Distributed Object-Oriented Database
Local autonomy of the individual databases in a distributed system is important as administrators of the individual databases often need to have complete control over how their data are structured, used and managed. Classical distributed databases support distribution transparency, replication …

An object-oriented database system for efficient information retrieval applications
This dissertation deals with the application of object-oriented database techniques to the problem of storage and access of information retrieval (IR) data, especially data that can be organized as a graph, such as a thesaurus encoded in semantic networks, or hypertext collections. Even traditional …

HOOD : a Higher-Order Object-Oriented Database model and its implementation
There is no accepted standard for the object-oriented database paradigm at present, which has led to different definitions of features and conformance requirements. HOOD is a Higher-Order Object-Oriented Database system which defines a meta-data model for specifying the requirements of an …

DMAS:A Display Measurement and Analysis System with an object-oriented database
… (DMAS) was designed and constructed using the object-oriented paradigm and object-oriented database (OODB) management techniques. The purpose of the system is to serve as a testbed for new generation measurement systems and for overcoming the limitations of conventional systems. This thesis …

Modelling of a temporal object-oriented geographic information system
… research has been performed in recent years in object-oriented technologies. First, object-oriented programming languages were developed and more recently object-oriented databases. Geographic information systems have also been the subject of research during this time. While many models have …

An interpreter for object comprehension query language
Object Comprehensions are a new query notation introduced in 1994 by Chan and Trinder to provide a declarative query language for object-oriented databases. Object Comprehensions allow queries to be expressed clearly, concisely, and processed efficiently, while incorporating many features that are …

A query language for information graphs
This thesis describes the Graph Object Access Language (GOAL) and optimization techniques to execute GOAL statements. GOAL can be used to retrieve information stored in an object-oriented database system modeled as an information graph. It is an extension of the LEND query language developed by …

Query optimization for Federated Database Systems: the Cyrano prototype
… processing of Cyrano, a prototype deductive object-oriented meta model for Federated Database Systems (FDBSs). The hypothesis was that query optimization techniques such as Semi-Naive algorithm and Magic-Sets Rewrite algorithm could be used to improve the performance of Cyrano prototype query …

The definition of a computer-based architecture for collaborative engineering design: Methodology, technology and implementation
… of reasoning techniques, extensions of current object-oriented database technology, and a team coordination methodology has been developed. This architecture has been implemented as a system called the Intelligent Design Environment for Engineering Automation (IDEEA). For reasoning, IDEEA …

Indeed: An active database for concurrent engineering
… This thesis describes a model for an active, object-oriented database which has been designed to support engineers involved in a joint design effort. This database provides the means to represent and manage information that has traditionally not been within the scope of computerized design …

Design and Implementation of XML in an Object-Relational Database
<p>Both RDBMS (Relational Database Management Systems) and ODBMS (Object- Oriented Database Management Systems) have their own advantages. For example, RDBMS is easy to understand and to access the data, and ODBMS has high performance to handle complex data. When we combine RDBMS and ODBMS's …

JPS : a distributed persistent Java system
Distributed persistent object systems provide a convenient environment for applications that need to manage complex long-lived data. Since Java has no persistence model built into it, the tremendous growth in the popularity of Java has generated a lot of interest in systems that add persistence to …
