Join Reordering by Join Simulation
2009 IEEE 25th International Conference on Data Engineering, 2009We introduce a framework for reordering join pipelines at runtime in a database system. This framework incorporates novel techniques for simulating the execution of a join pipeline using random samples and statistical summaries. Our simulation techniques provide accurate runtime cardinality estimates along all alternative execution paths of a join ...

Smart Joining/Smart Joining - Concept for Mechanical Joining 4.0
wt Werkstattstechnik online, 2016Der Fachbeitrag beschreibt Zusammenhänge zwischen verschiedenen – in einer Automobilproduktion relevanten – Randbedingungen und dem Fügeergebnis beim Halbhohlstanznieten in Form von mathematischen Modellen. Diese Modelle sowie neue Ansätze bei der Fügewerkzeuggestaltung bilden die Grundlage für die dargelegten Konzepte zur Weiterentwicklung der ...

Spatial applications frequently need to join two data sets based on some spatial relationship between objects in the two data sets. This operation, called a spatial join, is an expensive operation and in the past many algorithms have been proposed for evaluating the spatial join operation on a single processor system.

Understanding Joining — And Not Joining
2007Following the discussion of the growing professionalization in groups, this chapter presents two new sorts of evidence from surveys. First, it documents responses from group managers giving a top—down insider perspective on joining. Secondly, it reports on a survey of (environmental) non-members.

Semi-joins and anti-joins are two closely related join methods (options of join methods, actually) that the Oracle optimizer can choose to apply when retrieving information. The SQL language is designed to specify the set of data that the user wishes to retrieve, but to leave the decisions as to how to actually navigate to the data up to the database ...

Joined up thinking is the latest 'it' thing in strategy. joined-up thinking exudes low-brow simplicity and inclusivity, which in the current corporate climate is its philosophical and emotional strength. With past profit figures and share options increasingly viewed with suspicion, building or restoring a culture of trust is now high on the list of ...
