Visually querying object-oriented databases
… develop a visual query system for ODMG-compliant object-oriented databases, called QUIVER. QUIVER has a comprehensive expressive power; apart from supporting data types such as sets, bags, arrays, lists, tuples, objects and relationships, it supports aggregate functions, methods and sub-queries. …

Dynamic Online Data Clustering for Object -Oriented Databases
In this dissertation, we derive three models to clarify the relationships among the benefits and the penalties of dynamic online clustering, and database system parameters. The shortcomings of the existing implementations are discovered by qualitatively analyzing the resource consumption of each …

Adaptive Multi-Granularity Locking Protocol in Object -Oriented Databases
Object-oriented databases can be very useful for applications containing complex data models that are not well served by conventional databases. Although much research has been done on developing concurrency control protocols for conventional databases like relational databases over the last 30 …

Efficient indexing of spatial objects in object-oriented databases
… However, the index structures for standard databases are not suitable for the non-standard database applications such as geographical applications, CAD applications, VLSI designs and image processing. For non-standard databases, we need an index structure which preserves spatial …

Caching Derived Data in Object-Oriented Databases, and an Intelligent System Design for Selecting Their Materialization Strategies
To recompute from scratch, cache, or maintain a running-total is a database optimization question. The best answer depends in part upon usage patterns. For example, is total accessed frequently, or is the underlying table updated frequently? These usage patterns cannot necessarily be accurately …

A flexible approach for mapping between object-oriented databases and xml. A two way method based on an object graph.
… remain large amount of data held in structured databases and database management systems have been traditionally used for the effective storage and manipulation of large volumes of data. This raised the need for effective methodologies capable of smoothly transforming data between different …

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 …

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 …

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 …
