通过积累的技术提供优越的数据库管理系统

有一个问题总被提及:“你们比某某到底强在哪儿….”,考虑到ALTIBASE,是唯一真正将内存的速度与磁盘的存储特性,完美融合起来的混合架构数据库,这个问题很难回答,因为在我们所能达到的领域现在还没有人可以达到。因此这个问题的答案,需要从两个不同的方面去说。

Performance Advantage:

  • 相对于传统的磁盘数据库管理系统,Altibase的性能经常可以达到其10-20倍。在最近的一项针对MySQL的测试,ALTIBASE HDB的SELECT返回数据的速度是其77倍。这基本是把数据库迁移到ALTIBASE后,您可以期望的效果。

Other In-Memory Database Vendors:

  • 内存数据库领域竞争激烈,TimesTen,VoltDB,SolidDB和memcached等都表现出了其优秀的一面。但是经过对比测试,ALTIBASE的性能被一次又一次地证明不仅更快,而且更稳定可靠,无数据丢失。这背后的原因是,ALTIBASE HDB从开始就是基于内存来设计数据库,并在过去20年间不断进行完善。

The Hybrid Benefit:

  • 我们最大的优势,就是我们的引擎结合了内存与磁盘这两种不同的技术,并将其统一成一个引擎。Altibase使用统一的数据库引擎同时满足高速存取和大容量需求,无需应用程序开发人员通过程序来解决两者之间的配合问题。

 

请浏览下面一些具体的细节,并将我们的数据库与市场上的其它产品进行比较。如果您有任何具体问题,请随时联系Altibase的团队,我们将非常乐意为您提供帮助。
