TLDR
The history of database system research in the US is one of exceptional productivity and startling economic impact Barely twenty years old as a basic science research field, database research conducted with Federal support in the nation's universities and in its industrial research laboratories has fueled an information services industry estimated at $10 billion per year in the USA alone.Abstract:
The history of database system research in the US is one of exceptional productivity and startling economic impact Barely twenty years old as a basic science research field, database research conducted with Federal support in the nation's universities and in its industrial research laboratories has fueled an information services industry estimated at $10 billion per year in the US alone This industry has grown at an average rate of 20 percent per year since 1965 and is continuing to expand at this rate Achievements in database research underpin fundamental advances in communications systems, transportation and logistics, financial management, knowledge-based systems, accessibility to scientific literature, and a host of other civilian and defense applications They also serve as the foundation for considerable progress in basic science in various fields ranging from computing to biologyread more

An Efficient Algorithm for Mining Association Rules in Large Databases
TL;DR: This paper presents an efficient algorithm for mining association rules that is fundamentally different from known algorithms and not only reduces the I/O overhead significantly but also has lower CPU overhead for most cases.

Query evaluation techniques for large databases
TL;DR: This survey describes a wide array of practical query evaluation techniques for both relational and postrelational database systems, including iterative execution of complex query evaluation plans, the duality of sort- and hash-based set-matching algorithms, types of parallel query execution and their implementation, and special operators for emerging database application domains.

Knowledge discovery in databases: an overview
TL;DR: After a decade of fundamental interdisciplinary research in machine learning, the spadework in this field has been done; the 1990s should see the widespread exploitation of knowledge discovery as an aid to assembling knowledge bases.

Hilbert R-tree: An Improved R-tree using Fractals
Ibrahim Kamel,Christos Faloutsos +1 more
TL;DR: In this article, the Hilbert R-tree structure is proposed to facilitate the deferred splitting in R-trees by proposing an ordering on the R -tree nodes, in the sense that it should group similar data rectangles to gether, to minimize the area and perimeter of the resulting minimum bounding rectangles.

Overview of multidatabase transaction management
TL;DR: It is argued that the multidatabase research will become increasingly important in the coming years and basic research issues in multid atabase transaction management are outlined, followed by a discussion of open problems and practical implications.
