Johann Christoph Freytag. Part of the Lecture Notes in Computer Science book series (LNCS, volume 261).

Johann Christoph Freytag. Chapters Table of contents (7 chapters). About About this book. This book investigates the problem of translating relational queries into iterative programs using methods and techniques from the areas of functional programming and program transformation. The first part presents two algorithms which generate iterative programs from algebra-based query specifications.

Johann Christoph Freytag, Translating relational queries into iterativeĀ . Notes on the FP Style of Functional Programming. The first algorithm translates query specifications into recursive programs

Johann Christoph Freytag, Translating relational queries into iterative programs (transformation, evaluation), 1985. In Functional Programming and its Applications. The first algorithm translates query specifications into recursive programs. Those are simplified by sets of transformation rules before the algorithm generates the final iterative form. The second algorithm uses a two-level translation that generates iterative programs faster than the first algorithm.

Computer systems are exceptionally good at crunching numbers, producing exact parameterisations and exploring large numbers of alternatives

Computer systems are exceptionally good at crunching numbers, producing exact parameterisations and exploring large numbers of alternatives. An ideal data mining system should, we would argue, offer the above characteristics and use the best features of both the user and the computer in producing its answers.

Lecture Notes in Computer Science is a series of computer science books published by Springer Science+Business Media since 1973. The series contains proceedings, post-proceedings, and monographs. In addition, tutorials, state-of-the-art surveys, and "hot topics" are increasingly being included. Two sub-series are: Lecture Notes in Artificial Intelligence. Lecture Notes in Bioinformatics. Monographiae Biologicae, another monograph series published by Springer Science+Business Media.

This book investigates the problem of translating relational queries into iterative programs using methods and techniques from the areas of functional programming and program transformation. The first part presents two algorithms which generate iterative programs from algebra-based query specifications. While the first algorithm is based on the transformation of recursive programs, the second uses functional expressions to generate the final iterative form. In the second part the same techniques generate efficient programs for the evaluation of aggregate functions in relational database systems. In several steps, programs which perform aggregation after sorting, are transformed into programs which perform aggregation while sorting. The third part then investigates the Lisp-dialect T as a possible implementation language for database systems. The book describes all transformations by transformation rules. The reader can expect a formal treatment of the proposed transformations which provide the basis for proving the correctness of the algorithms and, at the same time, give important insight into the techniques and methods developed for the transformation. Additionally, the high-level, detailed description of the algorithms immediately leads to their implementation and allows their extension to meet new requirements. Overall, the use of transformation rules and transformation methods introduces a new approach to query processing in relational database systems.
