In-memory Database System for Java

eXtremeDB JNI in-memory database provides the fastest database solution in Java.

The in-memory database system (IMDB) for the fastest and most efficient Java applications.

Use of in-memory database systems (IMDSs) has grown rapidly, as developers of enterprise as well as embedded software seek the benefits of “real” database features without the overhead inherent in saving records to permanent media.

IMDSs store records in main memory, resulting in performance an order of magnitude faster than traditional, file system-based database management systems (DBMSs). In-memory databases’ streamlined design can also greatly reduce code and CPU footprint.

McObject, developer of the eXtremeDB in-memory database, offers the following information resources, to help determine whether an IMDS is right for your Java application.

Built for speed and reliability

eXtremeDB was designed from the beginning to maximize database speed, flexibility and reliability for professional developers.  Review these lists of features to look for it speed matters to your project, and if reliability is important.

Introducing the eXtremeDB JNI in-memory database system

The eXtremeDB In-memory database system with its Java Native Interface (JNI) provides the fastest database solution in Java.

eXtremeDB manages data entirely in main memory, eliminating file I/O, cache management and other overhead of disk-based database systems. With the JNI, developers work with eXtremeDB (which is written in C/C++) entirely from within Java, leveraging Java’s reflection capability to discover database classes and their fields that are defined in the application, via class definition syntax.

The result is that the database runtime executes with the speed of compiled C/C++ code, while the developer’s experience is of working with plain old Java objects (POJOs).
