Oracle公司发布内存级数据库更新程序

Oracle aims at mainstream with updated in-memory database

Oracle Corp. today released an update to the TimesTen in-memory database it acquired a few months ago and plans to promote the product to a broader audience of enterprise customers.

In-memory databases typically reside in the midtier alongside applications and store data in main memory rather than on disk, allowing it to be retrieved very quickly. They are used for applications where extremely fast response times are critical, such as in the financial services, telecommunications and networking industries.

Investment houses use TimesTen to store current stock price information, for example, which they need to quickly make trading decisions. Mobile operators use the software for billing, so that they can quickly determine whether a caller has enough prepaid credit to place a call.

AMTeam.org消息：Oracle公司今天准备发布它的名为TimesTen的内存级数据库更新程序，并且准备把这个产品推广到更多的企业级用户。

内存级数据库通常位于整个应用程序的中间层，它存储在内存中，而不是硬盘中，这样它的响应时间可以非常的短。因此，这种数据库特别适合金融，电信和网络企业，这些需要响应时间极为苛刻的行业。

举例来说，投资公司利用TimesTen的内存级数据库来存储股票价格信息，通过这个数据库，可以很快的把需要的信息读出来，并且进行投资决策。移动手机用户在线支付帐单的时候，需要首先检查是否有足够的金额来支付。

市场目前对此表示了积极的态度。
