Regular readers who are familiar with my blog will be also familiar with my interest in NuoDB. It is a very innovative new age database which follows 100% SQL, ACID and Elastically Scalability. Here is an earlier article on this subject where we explain why sharing will no more required due to the implementation of the NuoDB.
Each NuoDB database consists of at least three or more processes that enable a single database to run across multiple hosts. These processes include a Broker, a Transaction Engine and a Storage Manager. Brokers are responsible for connecting client applications to Transaction Engines and maintain a global view of the network to keep track of the multiple Transaction Engines available at any time. Transaction Engines are in-memory processes that client applications connect to for processing SQL transactions. Storage Managers are responsible for persisting data to disk and serving up records to the Transaction Managers if they don’t exist in memory.
