DataBlitz is a general purpose main memory database management system, developed by Lucent Bell Labs Research from 1993 to 1995. It replaced various home-grown database products used throughout Lucent beginning in 1997. It was originally named "Dali", and provided recovery and concurrency control features. Later, Dali was renamed as "DataBlitz". DataBlitz provides a platform for building high-performance shared memory applications that can survive failures or organize large amounts of data with features suited to many applications. Applications for DataBlitz include: * Switching and call routing in telecommunications * Real-time billing * High-performance Web servers * Financial trading applications * Data caching ==Features of DataBlitz== *Architecture for high performance * *No disk access for read operations and limited disk access for write operations * *All algorithms optimized for memory rather than disk * *Direct shared memory access to data * *Native C++ API for faster data access * *Support Multithread applications. *Full Transaction Semantics * *Atomicity * *Consistency * *Isolation * *Durability *High Availability * *Data replication to enhance availability and redundancy * *Asynchronous and Synchronous data replication * *Multi level Recovery to handle all kinds of failures * *Enhanced Fault Tolerance * *Code-word and Memory protection to detect and prevent data corruption due to stray application pointers *Fuzzy checkpoints that only minimally interfere with transaction processing *Relational C++ interfaces to optimize CPU cycles *Supports a broad subset of ANSI SQL 99, using Dharma SQL engine *Support SQL, ODBC and JDBC through Dharma SQL engine. *On-line backup and restore facility 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Datablitz」の詳細全文を読む スポンサード リンク
