New C# Interface for eXtremeDB In-Memory Database System (IMDS) Accelerates .NET Framework Development & Applications

April 27, 2011 — McObject®, an innovator in database systems for real-time applications, has released a C#/.NET Framework application programming interface (API) for its eXtremeDB® In-Memory Database System (IMDS) and related product family. The new API streamlines Windows software creation by enabling developers to work naturally with eXtremeDB entirely within C#’s object-oriented domain, while delivering eXtremeDB’s unparalleled run-time speed and efficiency.

For organizations already using C# and .NET, the new eXtremeDB API delivers the speed of a compiled C language database run-time, with the convenience of using a familiar development environment. Developers work with the real-time database entirely from within C#. There is no external database definition, and no requirement to compile a database schema. Instead, the API relies on C#’s reflection capability to discover database classes and their fields that are defined in the application, in the class definition syntax. This streamlines coding, and the developer's experience is one of working with plain old C# objects.

Optionally, the C# class definitions can be used to generate a schema that, in turn, can be processed by McObject’s schema compiler, so that C/C++ and C# programs can use the same database.

With the new API, eXtremeDB delivers the fastest possible DBMS solution for C# applications. The interface reduces development time and accelerates run-time performance across software categories, from real-time enterprise systems to embedded solutions.

“Microsoft Windows represents a key platform for performance-intensive and mission critical applications. The .NET framework’s benefits include enhanced developer productivity, stability and performance,” McObject Co-Founder and CEO Steve Graves said. “McObject’s new C# interface greatly improves eXtremeDB’s integration with a powerful and increasingly popular .NET language, bringing significant value to developers of demanding Windows applications such as trading platforms and industrial control.”

eXtremeDB’s breakthrough performance stems from its streamlined architecture that manages data entirely in main memory and within the application’s address space, eliminating file I/O, cache management, inter-process communication and other overhead found in database systems that incorporate disk storage and/or a client-server architecture. The resulting minimal latency has driven eXtremeDB’s adoption in performance-intensive applications ranging from telecom call routing and combat jet avionics, to securities trading platforms and social network news feeds. eXtremeDB’s simplified design also reduces CPU demands, extracting maximum performance from a given chipset – and enabling use of less powerful (and less expensive) hardware, when cost-containment is important.

The reflection capability in C# is used to discover database classes and their fields that are defined in the application, via class definition syntax.


With the eXtremeDB C# API, C# class definitions use attributes (defined by brackets) to indicate a database characteristic.

With eXtremeDB’s new interface, C# developers obtain the following features:
  • Database responsiveness measured in microseconds
  • eXtremeDB In-Memory Database System core in-memory architecture
  • Flexible on-disk and hybrid storage (eXtremeDB Fusion)
  • Multiple database indexes: B-tree, R-tree, Hash, Custom, Patricia trie, KD tree
  • Highly scalable via 64-bit support and a multi-version concurrency control (MVCC) transaction manager
  • Distributed database capability (eXtremeDB Cluster)
  • Fault-tolerance (eXtremeDB Cluster and eXtremeDB High Availability)
  • Transaction logging
  • Small footprint of 150K or less
  • ACID (Atomic, Consistent, Isolated and Durable) transactions
