  • 2D+ string: a spatial metadata to reason topological and directional relationships

    Publication Year: 1999, Page(s):112 - 121
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (118 KB)

    Spatial relationships have gained increasing attention in spatial databases. Reasoning spatial relationships is very expensive since it requires massive geometric computations. In particular, reading and comparing information to reason directional and topological relationships can be repeated as they are processed separately in previous works. In order to avoid the repetition and improve the perfo... View full abstract»

    Summary form only given. The LITCHI project (Logic-based Integration of Taxonomic Conflicts in Heterogeneous Information Systems) aims to develop software to enable the automated detection and, where possible, resolution of conflicts in taxonomic checklists. A taxonomic checklist is a list of the names of species (and other taxa) used within a particular biological database. Since species names ar... View full abstract»

    In many scientific domains, experimental devices or simulation programs generate large volumes of data. The volumes of data may reach hundreds of terabytes and therefore it is impractical to store them on disk systems. Rather they are stored on robotic tape systems that are managed by some mass storage system (MSS). A major bottleneck in analyzing the simulated/collected data is the retrieval of s...

  • Building a star join schema using SQL Server

    Publication Year: 1999
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (168 KB)

    We construct a star join schema and show how this schema can be created using the basic tools delivered with SQL Server 7.0. The major objectives are to keep the operational database unchanged so that data loading can be done without disturbing the business logic of the operational database. The operational database is an expanded version of the Pubs database (a sample database about a fictitious ... View full abstract»

    Presents DML (Data Model tools for L-systems). This work combines a novel application area with databases in bioinformatics. DML allows the specification of database structures and queries in terms of objects and relations that are specific to scientific L-system applications. L-systems have been used in many scientific areas. However, not much consideration has been given to persistent storage an... View full abstract»

    Over recent years, international initiatives such as the 1993 UN Convention on Biological Diversity have highlighted the need for information about species diversity on a global scale. However, attempts to build global information systems by integrating smaller, independently created biodiversity databases have been hampered by differences in the sets of species names used. Some databases use diff... View full abstract»

    Very long running queries in database systems are not uncommon in non traditional application domains such as image processing or data warehousing analysis. Query optimization, therefore, is important. However, estimates of the query characteristics before query execution are usually inaccurate. Further, system configuration and resource availability may change during long evaluation period. As a ... View full abstract»

    Different models to estimate the performance of tree-based index structures exist. Materialized aggregates in the inner nodes of such index structures are used to speed up range queries on aggregates. This is achieved by avoiding traversing the index tree down to the leaves through aggregates precomputed in the inner nodes. None of the existing models deals with these aggregated data. In this pape... View full abstract»

    Multidimensional analysis in online analytical processing (OLAP), and scientific and statistical databases (SSDB) use operations requiring summary information on multidimensional data sets. Most common are aggregate operations along one or more dimensions of numerical data values and/or on hierarchies defined on them. Simultaneous calculation of multidimensional aggregates are provided by the Data... View full abstract»

    The coming high energy physics experiments will store Petabytes of data into object databases. Analysis jobs will frequently traverse collections containing millions of stored objects. Clustering is one of the most effective means to enhance the performance of these applications.

    The response time of DSS (decision support system) queries is typically several orders of magnitude higher than the response time of OLTP (online transaction processing) queries. Since DSS queries are often submitted interactively, techniques for reducing their response time are becoming increasingly important. We argue that caching of query results is one such technique particularly well suited t... View full abstract»

    We present a query system that has been implemented in a practical biological database-GPCRDB. Distinguishing features of this system include: smart query relaxation and smooth integration of navigation with conventional language based query functions. Query relaxation is required due to the fact that queries are not always effective (in other words, expected results are frequently not achieved), ... View full abstract»

    Scientific databases must be able to efficiently run subset retrievals of multidimensional data sets. If the data sets are very large, significant retrieval speedups can be obtained via parallelism. In this paper, we present a new parallel distributed shared-nothing R-tree architecture. We provide experimental results demonstrating actual speedups for several synthetic and real data sets. In addit... View full abstract»

    The object-relational database management system (ORDBMS) offers many potential benefits for scientific, multimedia and financial applications. However work remains in the integration of domain-specific class libraries into ORDBMS query processing. A major problem is that the standard mechanisms for query selectivity estimation, taken from relational database systems, rely on properties specific t... View full abstract»
