This book was released on 1991 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Database programming languages like O2, E, and O++ include the ability to iterate through a set. Nested iterators can be used to express joins. This paper describes compile-time optimizations similar to relational transformations like join reordering for such programming constructs. This paper also shows how to use a standard transformation- based optimizer to optimize these joins. An optimizer built using the EXODUS Optimizer Generator [GRAE87] was added to the Bell Labs O++ [AGRA89] compiler. We used the resulting optimizing compiler to experimentally validate the ideas in this paper. The experiments show that this technique can significantly improve the performance of database programming languages."

This book was released on 1992 with total page 410 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Database programming languages like O2, E, and O++ include the ability to iterate through a set. Nested iterators can be used to express joins. Without program analysis, such joins must be evaluated using a tuple-at-a-time nested-loops join algorithm, because otherwise program semantics may be violated. Ensuring that the program's semantics are preserved during transformation requires paying careful attention to the flow of values through the program. This thesis presents conditions under which such transformations can be applied. This thesis then shows how to use a standard transformation-based optimizer to optimize these joins

Book excerpt: The analysis shows that the transformations can significantly reduce the number of I/Os performed, even when both the initial and transformed programs use the same join method."

Download or read book Database Programming Languages DBPL 4 written by Catriel Beeri and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fourth International Workshop on Database Programming Languages - Object Models and Languages (DBPL-4) took place in Manhattan, New York City, 30 August-1 September 1993. The areas of interest and the format of DBPL-4 focused on the integration of programming languages, object models, type systems and database systems. As in the previous DBPL workshops, the setting was informal, allowing the participants to actively discuss and argue about the ideas presented in the talks. The comments and remarks made by the participants during and after the presentations were taken into account in the preparation of the final versions of the papers. The result, we believe, is a set of excellent papers. The DBPL sequence is closely related to the sequence of International Workshops on Persistent Object Systems (POS), first started in 1985. While the DBPL workshops focus on language and model issues, the POS workshops have focused on implementation issues; thus the two sequences complement each other. Many researchers participate in both workshop series. The eight sessions of the technical program of DBPL-4 were as follows: 1. Bulk types and their query languages (two sessions). 2. Object models and languages. 3. Data types with order. 4. Mechanisms to support persistence, reflection, and extensibility. 5. Query optimization and integrity constraints. 6. Logic-based models. 7. Implementation and performance issues.
