    Summary form only given, as follows. Data mining applications deployed in industry are aimed at satisfying two problems organizations face: customer intimacy and better utilization of data assets. These applications can be divided into those that use micro-mining, i.e. single-mining-component desktop systems, and those who use macro-mining, i.e. multi-component server-based systems. The macro-mini... View full abstract»

    Summary form only given, as follows. Over the past few years, OLAP vendors have engaged in a debate regarding relational versus multidimensional data stores. This debate has obscured the more significant problems facing today's OLAP customers: managing the exponential growth generated by multidimensional pre-aggregations, and architectural support for a wide array of OLAP data models.

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (81 KB)

    Summary form only given. ROL (Rule-based Object Language) is a deductive object-oriented database system. It provides a uniform language for defining, querying and manipulating a database. The ROL language integrates important features of deductive databases and object-oriented databases with well-defined declarative semantics. ROL also supports structured values, treating them as first-class citi... View full abstract»

    Algebraic transformation and optimization techniques have been the method of choice in relational query execution, but applying them in object-oriented (OO) DBMSs is difficult due to the complexity of OO query languages. This paper demonstrates that the problem can be simplified by mapping an OO data model to the binary relational model implemented by Monet, a state-of-the-art database kernel. We ...

    Virtual database (VDB) technology makes external data behave as an extension of an enterprise's relational database (RDBMS) system. VDB technology enables the rapid deployment of applications with at least one of the following characteristics: large numbers of data sources; data sources that are autonomous (i.e. there is no centralized control); or data sources that can have a mixture of structure...

    Advocates a desktop virtual reality (VR) interface to a geographic information system (GIS). The navigational capability to explore large topographic scenes is a powerful metaphor and a natural way of interacting with a GIS. VR systems succeed in providing visual realism and real-time navigation and interaction, but fail to cope with very large amounts of data and to provide the general functional... View full abstract»

    We propose a new compression algorithm that is tailored to database applications. It can be applied to a collection of records, and is especially effective for records with many low to medium cardinality fields and numeric fields. In addition, this new technique supports very fast decompression. Promising application domains include decision support systems (DSS), since fact tables, which are by f... View full abstract»

    The association of timestamps with various data items such as tuples or attribute values is fundamental to the management of time varying information. Using intervals in timestamps, as do most data models, leaves a data model with a variety of choices for giving a meaning to timestamps. Specifically, some such data models claim to be point based while other data models claim to be interval based. ... View full abstract»

    The utility and functionality of active capability (event-condition-action or ECA rules) has been well established in the context of databases. Today, most of the commercial relational database management systems (RDBMSs) offer some form of ECA rule capability. In addition, there are several research prototypes that have extended the ECA rule capability to object-oriented database management syste... View full abstract»

    Query languages for data with irregular structure use regular path expressions for navigation. This feature is useful for querying data where parts of the structure is either unknown, unavailable to the user, or changes frequently. Naive execution of regular path expressions is inefficient however, because it ignores any structure in the data. We describe two optimization techniques for queries wi... View full abstract»

    Image data is structurally more complex than traditional types of data. An image can be viewed as a compound object containing many sub-objects. Each sub-object corresponds to image regions that are visually and semantically meaningful (e.g. car, man, etc.). We introduce a hierarchical structure for image modeling that supports image retrieval, at both the whole-image and object levels, using comb... View full abstract»
