Column-oriented RDBMS which supports  Data warehouses, data marts, and other business intelligence (BI) / analytic databases  General purpose reporting databases  Read-intensive segments of an overall application where read/search/lookup portions of the application are served by an analytic/query database and the transactional segments (e.g. order entry, etc.) are managed by a traditional relational database

4.  Column-oriented architecture  Multi-threaded design.  Automatic vertical and horizontal partitioning  High concurrency  High-speed data loader  DML support  Transactional support: ACID-compliant transactional support is provided along with deadlock detection

5.  Crash recovery: InfiniDB provides full crash recovery capabilities  MVCC design  No need for indexing  Low Maintenance  ALTER TABLE is supported (add, drop)  Platform Portability  Logical Data compression

6.  InfiniDB uses both horizontal and vertical partitioning  No special storage needs for horizontal partitioning  Use of both partitioning reduces IO cost in both directions  No user intervention  Automatic partition drop

7.  Multi Version Concurrency Control  Concurrency control method commonly used by database management systems to provide concurrent access to the database  Multiple versions stored, but only one is the latest  Query operations are never blocked on a table  Query will always see the data as it existed at the time the query was issued.
