We describe the vision of being able to reason about the design space of data structures.
We break this down into two questions: 1) Can we know all data structures that is possible to …

This thesis investigates the specifics of modeling data for spatial, temporal and
spatiotemporal applications (STOSTA) in the presence of object-relational database systems …

In this paper we consider aggregate predicates and their support in database systems.
Aggregate predicates are the predicate equivalent to aggregate functions in that they can be …

In this article we present a concept for simplification of user-defined indexing for user-
defined data types in object-relational database systems. The concept is based on a …

In order to generate efficient execution plans for queries comprising spatial data types and
predicates, the database system has to be equipped with appropriate index structures, query …

One-and multidimensional extended objects represent a vital foundation of many non-
standard database applications, including temporal databases, geographic information …

There is often a need to get quick approximate answers from large databases. This leads to
a need for data reduction. There are many di erent approaches to this problem, some of …

Multidimensional access methods are considered to be a promising approach for providing
acceptable performance to analysis-centric applications. However, despite the large body of …

Many scientific applications deal with spatial, spatiotemporal and other multidimensional
indexing structures, typically managing millions of objects with arbitrary and complex …

Approaches to indexing and searching feature vectors are an indispensable factor to
support similarity search effectively and efficiently. Such feature vectors extracted from real …
