Systems designed for efficient retrieval of conventional data can be very inefficient at retrieving documents. Documents have more complex structure than conventional data, and th...
Text is a pervasive information type, and many applications require querying over text sources in addition to structured data. This paper studies the problem of query processing i...
In conventional database systems, performance is primarily measured by the number of transactions completed within a unit time. In real-time applications, timing and criticality c...
Modern object-relational database systems are capable of managing multimedia data, e.g. image, video and audio. In this paper we study how such universal database systems can be u...
Real-time database systems incorporate the notion of a deadline into the database system model. USUally, deadlines are associated with transactions, and the system attempts to exe...

This paper attempts to de ne an object-oriented database system. It describes the main features and characteristics that a system must have to qualify as an objectoriented databas...
We describe the integration of a structuredtext retrieval system (TextMachine) into an object-oriented database system (OpenODB). We use the external function capability of the da...
We present the PPOST-architecture (Persistent Parallel Object Store) for main-memory database systems on parallel computers, that is suited for applications with challenging perfor...
This paper describes issues encountered in the design and implementation of a parallel object-oriented database system. In particular, we find that the design of a client/server ...
Aggregation in traditional database systems is performed in batch mode: a query is submitted, the system processes a large volume of data over a long period of time, and, eventual...
