    • The present invention provides a method for managing a database connection, comprising the steps of: in responsive to a connection request of a first application, allocating an available connection for the first application; if there is no available connection, selecting a held connection being used by a second application; backing up connection context of the held connection; releasing the held connection; and allocating the held connection for the first application. Since connection context of the application has been restorably backed up, a connection of the application can be cut off and the connection re-scheduled when necessary. As a result, the connection utilization rate is enhanced. The present invention further provides a device and system that can manage a database connection based on the technology of connection pools.

    • 本发明提供了一种用于管理数据库连接的方法,包括以下步骤:响应于第一应用的连接请求,为第一应用分配可用连接; 如果没有可用连接,则选择由第二应用使用的保持连接; 备份所连接的连接上下文; 释放持有的连接; 以及为所述第一应用分配所保持的连接。 由于应用程序的连接上下文已被可修改地备份,所以应用程序的连接可以被切断,并且必要时重新安排连接。 结果,连接利用率提高。 本发明还提供一种可以基于连接池的技术来管理数据库连接的设备和系统。 (图5)

    • Seed keywords are leveraged to provide expanded keywords that are then associated with relevant advertisers. Instances can also include locating potential advertisers based on the expanded keywords. Inverse lookup techniques are employed to determine which keywords are associated with an advertiser. Filtering can then be employed to eliminate inappropriate keywords for that advertiser. The keywords are then automatically revealed to the advertiser for consideration as relevant search terms for their advertisements. In this manner, revenue for a search engine and/or for an advertiser can be substantially enhanced through the automatic expansion of relevant search terms. Advertisers also benefit by having larger and more relevant search term selections automatically available to them, saving them both time and money.
    • 使用种子关键字来提供扩展的关键字,然后与相关的广告商相关联。 实例还可以包括根据扩展的关键字定位潜在的广告客户。 采用反向查找技术来确定哪些关键字与广告商相关联。 然后可以使用过滤来消除该广告客户的不合适的关键字。 然后,这些关键字会自动向广告客户显示,作为其广告的相关搜索字词。 以这种方式,可以通过自动扩展相关搜索词来大大增强搜索引擎和/或广告商的收入。 广告商也可以通过自动获得更大更多相关的搜索词选项来获益,从而节省时间和金钱。
