Joins
Oracle Database provides several optimizations for joining row sets. This chapter contains the following topics: About Joins Join Methods Join Types Join Optimizations A join combines the output from exactly two row sources, such as tables or views, and returns one row source. The returned row source is the data set. A join is characterized by multiple tables in the WHERE (non-ANSI) or FROM ... JO
Parallel & Distributed Joins | www.systems.ethz.ch
Project Description The architectural changes introduced with multi-core processors have triggered a redesign of main-memory join algorithms for relational database systems. Join processing in database systems is a complex and a demanding operation. Traditionally, there have been sorting and hashing based approaches for implementing joins. However, in the last few years several diverging views hav

Designing algorithms for Map Reduce
Since the emerging of Hadoop implementation, I have been trying to morph existing algorithms from various areas into the map/reduce model. The result is pretty encouraging and I've found Map/Reduce is applicable in a wide spectrum of application scenarios. So I want to write down my findings but then found the scope is too broad and also I haven't spent enough time to explore different problem dom
