XA Transactions (2 Phase Commit): A Simple Guide
In the early days of computing, there was no need for distributed transactions. As number of applications increased, synchronization of the data become an important issue. Companies paid a lot to maintain synchronized systems in terms of data flow. As a result, the 2 phase commit protocol referred to as XA(eXtended Architecture) arose. This protocol provides ACID-like properties for global transac

CockroachDB is a distributed SQL database. The primary design goals are scalability, strong consistency and survivability (hence the name). CockroachDB aims to tolerate disk, machine, rack, and even datacenter failures with minimal latency disruption and no manual intervention. CockroachDB nodes are symmetric; a design goal is homogeneous deployment (one binary) with minimal configuration and no r

If all these new DBMS technologies are so scalable, why are Oracle and DB2 still on top of TPC-C? A roadmap to end their dominance.
(This post is coauthored by Alexander Thomson and Daniel Abadi) In the last decade, database technology has arguably progressed furthest along the scalability dimension. There have been hundreds of research papers, dozens of open-source projects, and numerous startups attempting to improve the scalability of database technology. Many of these new technologies have been extremely influential---some

Transaction Processing Concepts and Techniques
This course covers both the theoretical and pragmatic issues addressed by transaction processing systems. The premise of the course is that RPC is the key to structuring distributed computations, and that transactional RPC is the best way to handle the inevitable exceptions that arise. This generalizes the transaction concept from its traditional database domain to the broader context of client-se

Our vision is to introduce Augmented Reality into the everyday lives of everyone on this planet. Augmented Reality is a technology that enhances human vision with computer generated graphics. In order to achieve our vision, it is imperative to merge three currently distinct research fields into one: Computer Graphics, Computer Vision, and Human-Computer Interaction.
