TAILIEUCHUNG - The Lowell Database Research Self Assessment

Object Oriented (OO) and Object-relational (OR) DBMSs showed how text and other data types can be added to a DBMS and how to extend the query language with functions that operate on these extended data types. Current database systems have taken their first steps toward supporting queries across text and structured data; but they are still inadequate for integrating structured data retrieval with the probabilistic-reasoning characteristic of information. | The Lowell Database Research Self Assessment By Authors June 2003 1 Summary A group of senior database researchers gathers every few years to assess the state of database research and to point out problem areas that deserve additional focus. This report summarizes the discussion and conclusions of the sixth ad-hoc meeting held May 4-6 2003 in Lowell Mass. It observes that information management continues to be a critical component of most complex software systems. It recommends that database researchers increase focus on integration of text data code and streams fusion of information from heterogeneous data sources reasoning about uncertain data unsupervised data mining for interesting correlations information privacy and self-adaptation and repair. 2 Introduction Some database researchers have gathered every few years to assess the state of database research and to recommend problem areas that deserve additional focus. This report follows a number of earlier reports with similar goals including Laguna Beach California in 1989 1 Palo Alto California Lagunita in 1990 2 and 1995 3 Cambridge Massachusetts in 1996 4 and Asilomar California in 1998 5 . Continuing this tradition 25 senior database researchers representing a broad cross section of the field in terms of research interests affiliations and geography gathered in Lowell Mass. in early May 2003 for two days of intensive discussion on where the database field is and where it should be going. Several important observations came out of this meeting. Our community focuses on information storage organization management and access and it is driven by new applications technology trends new synergies with related fields and innovation within the field itself. The nature and sources of information are changing. Everyone is aware that the Internet the Web science and eCommerce are enormous sources of information and information-processing demands. Another big source is coming soon cheap microsensor technology that will
