This article mainly introduces "what is the improvement of eXtremeDB 6.0". In the daily operation, I believe that many people have doubts about the improvement of eXtremeDB 6.0. the editor has consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the questions of" what improvement is there in eXtremeDB 6.0"! Next, please follow the editor to study!

Federal Road, Washington, Oct. 27, 2014-McObject ®, a developer of innovative database system software, has announced the official release of its eXtremeDB ®in-memory database version 6.0 and related products. This upgrade adds a distributed query function to improve the data processing speed and scalability of the database by making use of processing power, memory and the bandwidth of multiple hardware nodes to perform query functions. Other improvements in version 6.0 benefit both developers and end users in terms of ease of development and operating system support. Using distributed query processing, eXtremeDB divides the whole database and processes distributed queries through multiple servers, CPU or CPU cores. In some cases, the performance of the database will be greatly improved by using multiple hosts to perform database operations in parallel.

Steve Graves, founder and founder of McObject CEO, said: "this' split horizon 'may be designed into new systems, as well as devices that are naturally derived from autonomous embedded systems and incorporated into the interconnected' Internet of things'. This device allows data collected from different places to be aggregated." There is a strong demand for distributed query processing throughout the market, but it is limited to areas related to automation and control. EXtremeDB has demonstrated its super performance in these areas, "Graves said." Application scenarios include applications in smart power station systems, where data are queried from the accelerometer of wind turbines to measure 'flutter', or from temperature sensors that can show bearing damage. The application of intelligent transportation systems optimizes traffic flow based on data collected from thousands of vehicles and infrastructure control points.

Other features of the new eXtremeDB 6.0also improve the database systems of developers and end users, including:

Support for Python

EXtremeDB 6.0can be integrated with Python. Python is a high-level language for fast algorithms, especially prototypes. Using Python, coupled with eXtremeDB's dynamic data definition language DDL, developers can quickly implement their ideas and quickly optimize database tables and indexes by testing code changes.

Support for avionics platform

This upgrade increases compatibility with VxWorks 653Commercial off-the-shelf platform (COTS) VxWorks CERT. The VxWorks 653 platform supports integrated modular avionics (IMa) applications with stringent security requirements. VxWorks CERT is designed to permit strict industry standard certificates, including RTCA DO-178 and EUROCAE ED-12, revised B and C.

Ternary model database index

Facilitate the "blur" and proximity matching of text characters. This feature of eXtremeDB is specially suitable for application scenarios that read license plate numbers and require partial crawling data to use wildcard functions.

More flexible transaction scheduling

In addition to using eXtremeDB's transaction first function, its multiple read single write (MURSIW) transaction manager can override the default "first in first out" scheduling policy within the priority level to support read-only or read-write logging.

Data compression

Version 6.0 adds the data compression function of memory and disk database, which reduces the storage cost and thus the purchase cost.

Override Index option

EXtremeDB 6.0adds the function of storing key values in b-tree indexes of in-memory database. Usually such indexes contain only reference values to reduce storage footprint; this upgrade developer can store values in the index when applying data usage patterns to optimize this.

Evolution and improvement of binary structure

With this feature, eXtremeDB can save the database as a binary image and restore it with a changed schema or design. Version 6. 0 extends this feature to eXtremeDB cluster components.

Encryption extension

Support for RC4 encryption, which uses user-supplied passwords to organize unauthorized access. Version 6.0 uses this encryption in databases that are managed entirely by main memory.

At this point, the study of "what is the improvement of eXtremeDB 6.0" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
