City of Hope National Medical Center serves as the data-coordinating center (DCC) for the first NCCN shared outcomes research project. A Web-based database system has been designed and implemented over the Internet. Cancer centers located all over the United States are submitting data to this system that accommodates varying levels of database expertise and capabilities. The application is browser independent and incorporates several unique design, confidentiality, and security features, such as the use of \"ghost buttons\" and a \"secret agent\" approach to security. New SQL and Web-enabled features in the SAS statistical software package are integrated into this system as well. A demonstration of the NCCN database system is presented.","PeriodicalId":120937,"journal":{"name":"Proceedings. Tenth International Conference on Scientific and Statistical Database Management (Cat.

A workflow describes the individual tasks performed in these procedures and their interrelationships. Current workflow management systems (WFMSs) use a database management system (DBMS) to store task descriptions, and implement all workflow functionality in modules that run on top of the DBMS. Motivated by scientific workflows, we propose a much more DBMS-centric architecture, in which conventional database technology provides much of the desired scientific WFMS functionality. A key element of our approach is viewing the workflow as a web of data objects interconnected with active links that carry process descriptions. The workflow is fully defined as a database schema, and its execution is the gradual buildup of an instance of this schema through the active object links. For our work, we use the modeling and querying tools of Horse, the object-oriented DBMS that we have developed in the context of the Zoo Desktop Experiment Management Environment.","PeriodicalId":120937,"journal":{"name":"Proceedings.

This allows the more \"interesting\" areas of the problem space to be investigated in more detail than other areas. We present efficient ways for AMR-type applications to do input/output on the IBM SP2. We propose a disk layout that minimizes I/O costs for checkpoint/restart operations and investigate several allocation approaches to decluster grid data to multiple disks to enhance I/O parallelism for timestep/visualization operations. The experiments on the SP2 show that our strategies can help to shorten the I/O time to meet the performance requirements of the two types of I/O operations.","PeriodicalId":120937,"journal":{"name":"Proceedings.

Efficient information management and access systems are essential if the benefits of large-scale data capture programmes are to be realised. Data from existing ground-based monitoring systems are frequently under-used because of the difficulty of accessing the data and assessing whether they contain anything of relevance, and because of the delay between data capture and availability. The UK Environmental Change Network (ECN) is taking an integrated approach to information management which aims to achieve a seamless transition from data capture through to access and interpretation tools for the detection of patterns of change. The ECN is the UK's multi-disciplinary, long-term monitoring network, established to provide comparable, reliable, long-term runs of data on environmental change. Data quality standards are maintained through quality control, assessment and validation procedures, and rules for managing the resulting information within the data and meta-database. Rapid access to ECN meta-information and summary data is provided over the Internet using the World Wide Web with direct database links. A WWW prototype system for providing interpreted information based on simple models showing the main patterns in the data has been developed, with the eventual aim of providing an environmental information and interpretation system.","PeriodicalId":120937,"journal":{"name":"Proceedings.

As a result, modern database systems should be able to efficiently support that type of data. Towards this goal, appropriate extensions of multidimensional access methods can be exploited in order to index and retrieve spatiotemporal objects, satisfying users' demands. This paper introduces the basic specifications such a spatiotemporal index structure should follow, evaluates existing proposals with respect to the above specifications, and illustrates issues of interest involving object representation, query processing, and index maintenance.","PeriodicalId":120937,"journal":{"name":"Proceedings.

This area may benefit from the functionality offered by data warehousing. However, the special nature of clinical applications poses different and new requirements to data warehousing technologies, over those posed by conventional data warehouse applications. This article presents a number of exciting new research challenges posed by clinical applications, to be met by the database research community. These include the need for complex data modeling features, advanced temporal support, advanced classification structures, continuously valued data, dimensionally reduced data, and the integration of very complex data. In addition, the support for clinical treatment protocols and medical research are interesting areas for research.","PeriodicalId":120937,"journal":{"name":"Proceedings.

The paradigm is based on specifying and iteratively adjusting the Focus, Extent, and Density (FED) of the data attributes. The FED model supports highly complex queries of structured data in an intuitive fashion, and is augmented with a visual interface composed of a set of simple yet powerful user interface controls for query specification. In addition, statistical aggregations are supported by the model. Finally, the FED model is compared to the SQL paradigm, and is shown to be well suited for mapping to a direct-manipulation graphical interface.","PeriodicalId":120937,"journal":{"name":"Proceedings.

The next generation GISs should benefit from modern software engineering technologies. A component-based design encourages a fast \"assembly\" of applications from high-level software building blocks. Following this approach a complex general-purpose geo-information system can be substituted by a family of specialized subsystems which due to the common design basis are open for mutual data exchange. We introduce GeoToolKit component software intended for the development of 3D/4D geo-scientific applications. We also present our experience in building different types of geo-scientific applications on top of GeoToolKit. We show that common data types inherited by diverse applications from the GeoToolKit spatial class hierarchy create an excellent basis for the database-level integration of heterogeneous geo-scientific data.","PeriodicalId":120937,"journal":{"name":"Proceedings.
