For hard real-time systems
A reliable database for the energy industry
At the very core of fast, flexible embedded and real-time systems.
eXtremeDB is a proven solution for managing the “always on” demands of energy and smart grid database management.
Up and down the energy industry supply chain, emerging solutions are generating a flood of data that must be captured and analyzed.
With help from McObject’s eXtremeDB, optimization technology can dramatically boost utilities’ power generation yields. Distribution networks can become self-healing and even bi-directional, enabling end-users to contribute power back to the grid. Buildings, factories and residences can fine-tune their consumption through intelligent control systems.
eXtremeDB/rt is the first (and currently only) hard real-time deterministic database management system, ideal for sensor data fusion. Learn what makes a DBMS hard real-time.
eXtremeDB is found in military, satellite and safety systems around the world that can’t afford to fail. Learn about High Availability for 99.999% uptime.

Why is the energy industry choosing the eXtremeDB product family for systems ranging from nuclear plant safety to solar power optimization?
Reliability
Robust
Software coding errors can compromise safety. eXtremeDB’s type-safe API is a key tool that eliminates a common category of bugs. Other advanced debugging features add the further stability demanded by smart grid data management.
Data integrity
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.
Fault-tolerance
Power generation and transmission applications are mission-critical. The eXtremeDB High Availability module provides a proven, “always on” database solution that can survive hardware and/or software failure.
Multi-layered security
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.
Performance
Core in-memory database system
With a core in-memory database system (IMDS) architecture eXtremeDB delivers responsiveness measured in microseconds, which is critical for applications that are responsible for grid or plant safety, or for making real-time decisions to optimize energy production.
Multi-core optimized
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.
Efficient
With a tiny footprint eXtremeDB is a practical choice for field-based devices that incorporate minimal hardware resources. Also runs in Kernel mode.
Scalability
Distributed query processing
Distributed query processing across multiple servers, CPUs and/or CPU cores accelerates performance – dramatically, in some cases – via parallel execution of database operations and by harnessing the combined processing power, memory and I/O bandwidth of many nodes rather than just one
Sharding
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.
Flexibility
A hybrid persistent and in-memory database
eXtremeDB is a hybrid database offering the strengths of the on-disk and all-in-memory approaches to data management in a single database system. Applications can blend persistent (i.e. flash or hard disk) and in-memory storage, enabling optimization for persistence and performance as well as cost and form factor. eXtremeDB began as an in-memory database system. Learn why this is important.
Columnar / Hybrid layout
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.
Open replication
Facilitates fine-grained data-sharing with enterprise systems (such as energy companies’ billing, analysis and commerce applications) with eXtremeDB Data Relay.
