, 2018 The key idea behind Inspector Joins is that during the I/O partitioning phase of a hash-based join, we have the opportunity to look at the actual data itself and then use this knowledge in two ways: (1) to create specialized indexes, specific to the given query on the given data, for optimizing the CPU cache performance of the subsequent join phase of ...

Given a multigraph \(G\) and an even subset \(T\) of \(V(G)\), a \(T\)-join is a set \(J \subseteq E(G)\) such that \(G(V,J)\) has odd degree of the nodes of \(T\) and even degree of the nodes of \(V \backslash T\), where \(V = V(G)\). A cut \(\delta (S)\) of \(G\) is a \(T\)-cut if \(S \cap T\) is an odd set.

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 ...

In new application areas of relational database systems, such as artificial intelligence, the join operator is used more extensively than in conventional applications. In this paper, we propose a simple data structure, called a join index, for improving the performance of joins in the context of complex queries.

The clinical environment of the hospital ward and clinic is where medical students become physicians by engaging with patients under the tutelage of clinician teachers. These formative experiences guide the students' regard and respect for patients, shape their nascent medical identities, and influence their confidence in their chosen profession.

22nd International Conference on Data Engineering (ICDE'06), 2006
We present a secure network service for sovereign information sharing whose only trusted component is an off-theshelf secure coprocessor. The participating data providers send encrypted relations to the service that sends the encrypted results to the recipients.

Fifth International Conference on Very Large Data Bases, 1979., 1979
A new operator, the entity join, is proposed as an extension to the relational model. While similar to the traditional join, it is based on common entities rather than matching representations. The entity join avoids a number of problems arising from the loose correspondence between names and entities, it rationalizes the traditional join, and it ...
