Embedded Databases: Building In ‘Always On’ High Availability

This Webinar about High Availability for Embedded Databases, highlights the issue of operational continuity. It answers the questions: how can a database system survive the failure of the software or hardware environment in which it operates? How can it deliver high performance as well as fault-tolerance? Led by McObject CEO Steve Graves, this Webinar presents development solutions. Learn how to address the “always on” needs of fault-tolerant systems, while taming these applications’ growing data complexity.

If operational continuity is important to your project we invite you to learn more about eXtremeDB High Availability.

We are a dedicated group of specialists.

Our only focus is database management systems. Did you find the Webinar about High Availability interesting? We invite you to review additional research, and evaluate our free trial software.

Is it an in-memory database system, or not?

When you hatch a database management system, it will, by design and implementation, be either an in-memory database system or an on-disk database management system. The choice affects the fundamental optimization strategies that will be baked into the database system code. To optimize an on-disk database is to minimize disk I/O, so its design will use extra CPU cycles and extra memory if doing so will reduce or eliminate I/O. Conversely, IMDSs by definition eliminate all disk I/O; their optimization is all about delivering the highest performance at a given level of processing power, thus reducing demand for CPU cycles is a key objective. And since memory is storage for an IMDS, reducing memory overhead (i.e. RAM consumed for anything other than storing data) is also a key objective.

A hybrid database

eXtremeDB enables the developer to combine in-memory and on-disk paradigms in a single database system. Specifying that data will be stored in memory (transient), or on disk (persistent), requires a simple database schema declaration. The resulting system retains in-memory strengths (speed, footprint, etc.), yet leverages the potential cost savings and durability of an on-disk database.

Mumbai-based 63 Moons, a global leader in offering technology and domain expertise in creating next-generation market solutions, has adopted the eXtremeDB IMDS in its real-time financial software. 63 Moons deployed eXtremeDB in its Microsoft Windows Server-based DOME (Distributed Order Management Engine) trading platform and in other products.

“eXtremeDB replaces the relational database management system (RDBMS) that previously supported middle-tier functions in existing products….A growing volume of data at this level of the system is what prompted our company to seek a database solution that offers greater efficiency than traditional RDBMS software, which has been a staple of financial markets for several decades.” – 63 Moons

BAE Systems integrates the eXtremeDB in-memory database for avionics in the Panavia Tornado GR4 combat jet. Within the aircraft’s Tornado Advanced Radar/Map Display Information System (TARDIS), eXtremeDB manages tactical information and is updated in real-time from multiple sources. The company chose eXtremeDB rather than developing its own database in order to reduce costs and shorten time-to-market.
