Database system reliability encompasses protection from loss of database availability, safeguards on data integrity, and resistant to database corruption caused by application software defects. Read a list of features to look for in a reliable database management system.

eXtremeDB offers built-in data management security at rest and in transit. Cyclic Redundancy Check (CRC) on the database page level detects any unauthorized modification to stored data.  AES encryption employs a user-provided cipher to prevent access or tampering.

eXtremeDB Multi-version Concurrency Control (MVCC) transaction manager boosts speed and scalability in multi-threaded, multi-core environments, which are increasingly the norm in energy industry applications.

eXtremeDB supports standard SQL/ODBC/JDBC, but also offers faster native C/C++, Java and C# (.NET) APIs. Information is stored as C/C++ data types (including structures, vectors and arrays), eliminating the overhead of conversion to SQL data types.

eXtremeDB offers elastic scalability when databases are partitioned (“sharded”), with each partition/shard managed by an instance of the DBMS server. Shards are typically distributed on a storage array (which may be a SAN) – with each server keeping a CPU core busy – or distributed across different physical servers with their own storage systems.

Traditional DBMSs bring rows of data into the CPU cache for processing. But time series data is naturally columnar, and handled more efficiently by a column-based layout. eXtremeDB stores time series data with a columnar layout, and “normal” data with a conventional row-based layout. The result is higher performance, resulting from a database system that best leverages the CPU cache speed and avoids costly (in performance terms) fetches from main memory.
