    • A method and apparatus for receiving inbound data on an I/O device wherein a request to receive inbound data is received. A direct-data-placement request-tag is generated and associated with a pre-allocated buffer when the request requires direct data placement. A non-direct-data-placement request-tag is generated when the request does not require direct data placement. The received request is then augmented with a generated request-tag and directed to a data interface unit. A data packet that includes a reply-tag and a payload is then received in the data interface unit. The payload is directed from the data interface unit into a pre-allocated buffer when the reply-tag correlates with a request-tag that is associated with a pre-allocated buffer. Otherwise, the payload is retrieved from the data interface unit when the reply-tag does not correlate with a request-tag that is associated with a pre-allocated buffer.
    • 一种在I / O设备上接收入站数据的方法和装置,其中接收到接收入站数据的请求。 当请求需要直接数据放置时,生成直接数据放置请求标签并将其与预先分配的缓冲区相关联。 当请求不需要直接数据放置时,将生成非直接数据放置请求标签。 接收到的请求随后用生成的请求标签进行增强并被引导到数据接口单元。 然后在数据接口单元中接收包括应答标签和有效载荷的数据包。 当应答标签与与预先分配的缓冲器相关联的请求标签相关时,有效载荷从数据接口单元引导到预先分配的缓冲器中。 否则,当应答标签与与预分配缓冲器相关联的请求标签不相关时,从数据接口单元检索有效载荷。

    • A method for analyzing database records using sampling includes querying a recipient database for recipients with attributes that match one or more specified recipient attributes, querying a sampling database for transactions with attributes that match one or more specified transaction attributes, where the sampling database stores a subset of transactions that are also stored in a transaction database, intersecting the recipients resulting from the querying of the recipient database and the transactions resulting from the querying of the sampling database based on attributes thereof to create a set of joined sample results, and determining an approximate full count value by extrapolating a count value associated with the set of joined sample results based on both a total number of recipients in the recipient database and a total number of transactions in the transaction database.
    • 用于使用采样来分析数据库记录的方法包括:对具有与一个或多个指定的接收者属性匹配的属性的收件人查询接收者数据库,向采样数据库查询具有与一个或多个指定事务属性匹配的属性的事务,其中采样数据库存储子集 还存储在事务数据库中的与从接收方数据库的查询获得的收件人相关的事务以及根据其属性查询抽样数据库而产生的事务,以创建一组连接的样本结果,并确定一个近似值 基于收件人数据库中的收件人总数和交易数据库中的总计交易数量,通过外推与所连接的样本结果集相关联的计数值的完全计数值。
