IBMs DB2 spatial extender: Managing geo-spatial information within the DBMS
free download
EXECUTIVE SUMMARY IBM has focused research efforts on creating an extensible data- management infrastructure for more than a decade. The results of these efforts have become a major component of IBMs DB2 Universal Database (UDB), the companys flagship object
A cost-effective method for providing improved data availability during DBMS restart recovery after a failure
free download
We present a cost-effective method for improving data availability during restart recovery of a data base management system ( DBMS ) after a failure. The method achieves its objective by enabling the processing of new transactions to begin even before restart recovery is Since the early 90, Geographical Information System (GIS) has become a sophisticated system for maintaining and analysing spatial and thematic information on spatial objects. DBMSs are increasingly important in GIS, since DBMSs are traditionally used to handle
The SAMOS active DBMS prototype
free download
We describe SAMOS, an active object-oriented database management system prototype. SAMOS offers a powerful rule definition language, including a small yet powerful set of event definition facilities. It is able to detect primitive and composite events automatically and
Integration of GIS and CAD at DBMS level
free download
ABSTRACT CAD and GIS have been designed for different applications but a tendency for convergence is increasing in the last years. For many different tasks integrations of GIS and CAD models are required. Currently there is no system that can easily integrate models from
Transparent integration of continuous media support into a multimedia DBMS
free download
ABSTRACT Multimedia Database Management Systems (MMDBMS) have to efficiently provide the specific functionalities required by time-dependent multimedia data types. During presentation playout, this requires support for continuous data delivery and media
ACOOD: An Approach to an Active Object Oriented DBMS .

A nactive DBMS ischaracterizedbyitsa bilitytomonitor and react to both database and nondatabase events in a timely and efficient manner [CHA89]. Research on active database systems can be found in the POSTGRES project [STON87a],[STON87b],[STON90], the
Maintaining reality: modelling 3D spatial objects in a Geo- DBMS using a 3D primitive
free download
The title of this report is Maintaining Reality. This title seems a little odd, but refers to the goal and final result of the research that is described in this report. The subtitle is Modelling 3D spatial objects in a Geo- DBMS using a 3D primitiveand says more about the contents of
Fuzzy analytic hierarchy based DBMS selection in turkish national identity card management project
free download
ABSTRACT Database Management Systems ( DBMS ) play an important role to support enterprise application developments. Selection of the right DBMS is a crucial decision for software engineering process. This selection requires optimizing a number of criteria
DBMS architecture-the layer model and its evolution
free download
The resulting abstraction hierarchy hides some properties of a system level (an abstract machine) from higher-layer machines. Furthermore, the implementation of higher-level operations extends the functionality of an abstract machine. System evolution is often
Ss-db: A standard science dbms benchmark
free download
In this paper, we propose a new benchmark for scientific data management systems called SS-DB. This benchmark, loosely modeled on an astronomy workload, is intended to simulate applications that manipulate array-oriented data through relatively sophisticated
Building a laboratory information system around a C++-based object-oriented DBMS
free download
MapBase is a laboratory information system that has been supporting a high-throughput genome-mapping operation for the last three years. We chose to build MapBase around a C++-based OODBMS because, like CAD, CASE, and GIS applications, MapBase must be
A rule-based query rewriter in an extensible dbms
free download
Query optimizers transform user submitted queries into a canonical form and then translate the canonical form into an efficient access plan. The first step of query optimization is known as query rewriting. This paper describes an integrated approach for query rewriting in an
Storing and using scale-less topological data efficiently in a client-server DBMS environment
free download
In this paper we present a data structure that stores the results of a generalisation procedure efficiently as a scale-less map inside a spatial DBMS . This structure makes is possible to interactively visualize polygonal subdivisions on any scale efficiently. This is done by
Implementation of honeytoken module in dbms oracle 9ir2 enterprise edition for internal malicious activity detection
free download
Information stored in companies databases is often the most valuable one and as a result database security is of great importance. It is a very complex task, however, to ensure database security without limiting capabilities and productivity of legal users. Honeytokens
The TEXTURE benchmark: measuring performance of text queries on a relational DBMS
free download
We introduce a benchmark called TEXTURE (TEXT Under RElations) to measure the relative strengths and weaknesses of combining text processing with a relational workload in an RDBMS. While the well-known TREC benchmarks focus on quality, we focus on
Management and 3D visualisation of pipeline networks using DBMS and AEC software
free download
Management and visualization of underground utilities have been always of a great concern in many countries. Insufficient, inaccurate and unclear information about location and depth of cables and pipelines cause various problems and even result in tragic
Monetdb, a novel spatial columnstore dbms
