Speedy transactions in multicore in-memory databases

Stephen Tu, Wenting Zheng, Eddie Kohler, Barbara Liskov, Samuel Madden
2013 Proceedings of the Twenty-Fourth ACM Symposium on Operating Systems Principles - SOSP '13  
Silo is a new in-memory database that achieves excellent performance and scalability on modern multicore machines. Silo was designed from the ground up to use system memory and caches efficiently.  ...  For instance, it avoids all centralized contention points, including that of centralized transaction ID assignment.  ...  Transactional memory Silo's goals (fast transactions on an in-memory database) resemble those of a software transactional memory system (fast transactions on arbitrary memory).  ...

2011 ACM Transactions on Database Systems  
In this article we describe MCDB, a database system that permits a wide spectrum of stochastic models to be used in conjunction with the data stored in a large database, without ever extracting the data  ...  Unfortunately, in practice this usually means extracting data from a database system into an external tool (such as SAS, R, Arena, or Matlab), and then running the analysis there.  ...  In our example, this might require going through each of the sales transactions for 2010 that are stored in the database.  ...
