The first Chinese large general relational database to be used in the overseas education sector.
Dameng exceeded the client’s initial service requirements in terms of improving performance indicators, optimizing query efficiency, reducing development costs, intensifying risk prevention and control and all other areas, significantly improving the service efficiency and levels of Thailand’s education sector.
The Thailand Education Cloud Project’s full name was the “Thailand Handheld Wireless Device Cloud Computing and Cloud Content Management Platform”. This project was mastered by the Thai Ministry of Education, with the Ministry of Information Industry assisting with its joint launch, and was based on the OTPC plan proposed by the Thai government (One Tablet Per Child Policy) in its implementation. The leading Thai TOT enterprise joined hands with Dameng to create this educational cloud platform and by upgrading and maintaining this educational cloud platform, comprehensively improved the quality of information sharing and general interest in elementary and secondary education.
The Thailand Education Cloud Platform is comprised of the client-side and service center. The service center is aimed at educational software developers and provides a digital library, the E-Lib, the educational software release platform APP-store and other customized software. It provides the client-side with online digital book downloads, reading, interactive study and other services. Over two million tablets have been issued, and because student class times are concentrated, the database needed to process concurrent data from over two million platforms simultaneously. Because there are a large number of platform subsystems on this platform service, with a large quantity of data and of differing data types, and involves the fusion of relative and non-relative data, there were strict functionality and performance requirements for the database.
With the Thailand Education Cloud facing a wide range of user groups, a gradually increasing volume of books, a continuous increase of front-end users, a vast number of user visits and other service demands, Dameng’s team adopted the data watch cluster software (DMDataWatch) for its service system database and the read/write separation cluster software (DMRWC) for its analysis system database, with both pieces of software using the real-time data synchronization software (DMHS) to conduct data transfer.
In order to guarantee that its millions of users could gain smooth access at the same time, the project adopted the DM7 original ecology MVCC’s relational database underlying technology, column storage, intelligent indexing, high efficiency compressor and other technology to upgrade the system’s access efficiency during periods of high concurrency; to cope with the constant increase in the volume of users, the current DMRWC adopted the “one primary two standby” model, and capacity can be expanded by dynamically adding standby nodes in the future depending on the actual situation.
To guarantee the stable operation of the platform and service data security, the project uses automatic scheduled backup and combines that with DMDataWatch to upgrade the system’s disaster recovery capabilities.
This project began operating online in October 2013 and has brought operation subsystems online since then. It has exceeded the client’s initial service requirements in terms of improving performance indicators, optimizing query efficiency, reducing development costs, intensifying risk prevention and control and all other areas, significantly improving the service efficiency and levels of Thailand’s education sector.
1. Easily coped with high concurrency demands: Met the requirements to simultaneously serve two million elementary and secondary school users studying online.
2. Effectively guarantees high system availability: With the support of Dameng’s data protection technology, the cloud platform can effectively dispose of various fault risks and realize the swift recovery and failover of services;
3. Significantly improved various core performance indicators: With the support of Dameng’s read/write separation technology, the cloud platform can fully meet the current high concurrency, high load, dynamic increase of resources and other demands.
4. Significantly reduce secondary development costs: Relying on the comprehensive ANSI SQL syntax support capacity, Dameng swiftly migrated the cloud platform’s data from SQL server 2005 to the Dameng database, with relatively few modifications to the original application.
