  • 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»

    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»

    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 paper presents a reclustering algorithm for independent objects contained in multiple possibly overlapping collecti... View full abstract»

    Recent database applications are typically oriented towards a large set of non-expert users and therefore they need to be equipped with suitable interfaces facilitating the interaction with the system. It has been pointed out that temporal data constitute a growing part of such recent applications. However, there are not many proposals of systems providing the user with a friendly and effective en... View full abstract»

    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»

    Online analytical processing (OLAP) technologies are being used widely, but the lack of effective means of handling data imprecision, which occurs when exact values are not known precisely or are entirely missing, represents a major obstacle in applying these technologies in many domains. The paper develops techniques for handling imprecision that aim to maximally reuse existing OLAP modeling cons... View full abstract»

    Many commercial database systems maintain histograms to efficiently estimate query selectivities as part of query optimization. Most work on histogram design is implicitly geared towards discrete or categorical attribute value domains. We consider approaches that are better suited for the continuous valued attributes commonly found in scientific and statistical databases. We propose two methods ba... View full abstract»

    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»

    The State University of New York at Buffalo is developing a geographic image retrieval system termed GiView. From a large-scale geographic image database, the system retrieves relevant images that contain parts similar to a given query image. The system extracts texture and color features of geographic images. One key design of the system is a practical image decomposition scheme called nona-tree ... 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»

    Data warehouses as well as a wide range of other databases exhibit a strong temporal orientation: it is important to track the temporal variation of data over several months or years. In addition, databases often exhibit append-only characteristics where old data is retained while new data is appended. Performing joins efficiently on large databases such as these is essential to obtain good overal... 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»
