ANTs Data Server (ADS) is a product of ANTs Software that uses 7 patented algorithms (which, if they are to be relevant, should be listed) in the only parallel transaction processing engine that does not use locks at any database level. The vendor claims that elimination of all data-locking allows for database performance 15 times greater than conventional database systems. ADS is universally compatible with Oracle, SQL-Server, and Sybase (although, if it doesn't do any data locking, this means that its behavior will be necessarily considerably different from any of these systems).

Possible Patents

6,760,726 System and method of managing concurrent operations on linked lists

There only seem to be two patents assigned to ANTs Software...

Concurrent tri-mode operation

ADS has three modes of operation, each optimized for specific workloads and hardware configurations. A single instance of ADS maximizes throughput by running in all three modes concurrently regardless of hardware configuration.

Client-Server mode provides multi-user access, scalability, and fault tolerance

Local (IPC) mode for faster application access to data co-located on the same server

Embedded (in-memory) mode links directly with your Java or C application, eliminating IPC costs, but correspondingly eliminating multiuser and fault tolerant access mechanisms

Platform Support

ADS is designed to be a standalone database, it can also be used to accelerate conventional database systems by offloading "hot spot" tables to the ANTs Data Server.
