eXtremeDB Fusion Eembedded Database System

Compatible Operating Systems: All

Supported Architectures: Platform independent

In the race to offer advanced features, consumer electronics devices manage ever-growing volumes of increasingly complex data. MP3 players organize tracks via meta-data and user input such as playlists and ratings. Embedded gaming software demands concurrent data access, event notification and fast, flexible search. Set-top boxes offer a rich store of programming choices. Even cell phones must organize messages—often in multiple formats—logically, and retrieve them quickly.

Consumer electronics manufacturers rely on McObject’s eXtremeDB Fusion hybrid in-memory/on-disk embedded database system to meet the stringent performance, reliability and form factor demands, as well as the RAM and CPU limits, of new smart devices. eXtremeDB Fusion offers stability, scalability and extensibility proven in years of deployment. Its streamlined architecture—designed from scratch for embedded apps—makes for a code size as small as 50K. This tiny footprint enables use of less memory and lower-end processors, for manufacturing cost savings that drop to the bottom line.

Uniquely, eXtremeDB Fusion is optimized for in-memory and on-disk data storage in a single embedded database system, providing unparalleled flexibility. In-memory data management excels at real-time performance. Yet byte-for-byte, disk storage can be cheaper than memory. Disk storage can also take less physical space. So for small form-factor devices with large storage needs, such “spinning
memory” might be preferred.


  • Lower Costs – Streamlined architecture enables striking efficiency gains, leading to lower component (RAM and CPU) costs.
  • Hybrid data management – eXtremeDB Fusion combines in-memory and on-disk data storage in one embedded database system, to optimize applications for speed, persistence, cost and form factor.
  • Concurrent Access – Databases can be created in local or shared memory. Multiple processes and threads can share databases; a remote interface allows network access.
  • Better, Safer Code – Type-safe, intuitive C/C++ API shortens database learning curve, produces more easily maintained code, and eliminates costly run-time errors.
  • Industry-tested solution – Siemens, Philips, JVC, Genesis Microchip and other electronics leaders embed McObject’s database in their consumer devices.


  • Code size from 50K to 250K, depending on the platform and features.
  • Source code and object code licenses are available.
  • Transaction performance measured in microseconds.
  • Persistence via streaming to disk; non-volatile RAM (NVRAM or battery RAM) support; High Availability edition.
  • Multiple data and index types supported, plus sophisticated debugging features.
