eXtremeDB 6.0 official release: increased scalability and distributed query Speed _ database other

Federal Road, Washington, October 27, 2014----mcobject® Company, as an innovative database system software developers, announced its extremedb® memory database version 6.0 and related products have been officially released. This upgrade increased the distributed query function, through the use of processing power, memory and multiple hardware nodes to perform query function bandwidth to improve the database processing speed and scalability. 6.0 other improvements, both for ease of development and for operating system support, can benefit both developers and end users. Using distributed query processing, eXtremeDB divides the whole database into distributed query processing through multiple servers, CPUs or CPU cores. In some cases, using multiple hosts to perform database operations in parallel, the performance of the database will be greatly improved.

Steve Graves, CEO and founder of McObject, said: "This ' horizontal segmentation ' may be designed into a new system, and it is also a device that can be derived and incorporated into the interconnected ' IoT ' of proprietary embedded systems. This device allows aggregation of data collected from different places. "There is a strong demand for distributed query processing across the market, but it is limited to areas related to automation and control." eXtremeDB has demonstrated its superior performance in these areas, "Graves said," The application scenarios include: Applications in intelligent power Station systems, querying data from the accelerometer on wind turbines to measure ' Vibration, can also be queried from the temperature sensor that can display the bearing damage, and in the application of the intelligent transportation system to optimize traffic flow based on data collected from thousands of vehicles and infrastructure control points.

New eXtremeDB 6.0 Other features also improve database systems for developers and end users, including:

Support Python

eXtremeDB 6.0 can be integrated using Python. Python is a high-level language for fast algorithms, especially for prototyping. Using Python, coupled with extremedb Dynamic Data definition Language DDL, developers can quickly implement their ideas by testing the changes in the code, database tables and indexes for rapid optimization.

Support Avionics Platform

This upgrade adds to the compatibility of the VxWorks 653 commercial off-the-shelf Platform (COTS) VxWorks cert. The VxWorks 653 platform supports integrated Modular avionics (IMA) applications that are demanding for security. The VxWorks cert is designed to permit strict industrial standard certificates, including RTCA DO-178 and Eurocae ED-12, revision B and C.

Ternary Model Database Index

Facilitates "blur" and proximity matching of text characters. This feature of eXtremeDB is specifically designed to read license numbers and applications that require the use of wildcard features for partial crawl data.

More flexible transaction scheduling

In addition to using EXTREMEDB transaction priorities, its multiple read single write (MURSIW) transaction manager can override the default "FIFO" scheduling policy at the priority level to support read-only or read-write logging.

Data compression

The 6.0 version increases the memory and disk database data compression capabilities, reducing storage costs and thus reducing acquisition costs.

Overwrite index options

eXtremeDB 6.0 adds the ability to store key values in the memory Database B-tree index. Typically, such indexes contain only reference values to reduce storage footprint; The upgrade developer can store the values in the index when applying the data usage pattern to optimize this.

Evolution Enhancement of binary structure

With this feature, eXtremeDB can save the database as a binary image and recover it with a changed schema or design. The 6.0 version extends this feature to the eXtremeDB cluster component as well.

Encryption extension

Supports RC4 encryption, which uses a user-supplied password to organize unauthorized access. The 6.0 version uses this encryption in a database that is fully managed by the main memory.
