    • The system of the present invention provides for a method and apparatus of displaying portions of text from multiple documents over multiple databases related to a search query. The initial step in this method is to identify a search query. Based on this identification, a search against multiple databases is initiated. In particular, the computer system identifies auxiliary databases either within a network or between networks that are likely to contain documents relating to terms in the search query. Upon identification of these databases, the databases are then searched to identify those documents relating to the identified query. The various sets of identified documents from multiple databases are then returned and processed to create an ordered ranking for the returned documents. Text portions from the highest ranking documents across the multiple databases are then automatically displayed to the user.
    • 本发明的系统提供了一种在与搜索查询相关的多个数据库上显示来自多个文档的部分文本的方法和装置。 该方法的初始步骤是识别搜索查询。 基于此识别,启动对多个数据库的搜索。 特别地,计算机系统在网络内或可能包含与搜索查询中的术语相关的文档的网络之间识别辅助数据库。 在识别这些数据库之后,搜索数据库以识别与所识别的查询相关的那些文档。 然后返回并处理来自多个数据库的各组已识别文档,以便为返回的文档创建一个排序顺序。 然后,跨多个数据库的最高排名的文档的文本部分将自动显示给用户。

    • The present invention is a computer system for modifying a database which comprises a computer that modifies records stored in a database. In the process for modifying records in the database, addresses to memory locations in a disk storage unit are accessed during the commit phase by first checking the address space in a transaction log. The computer system of the present invention operates by committing transactions without locking out readers. This is possible because any changed data in the database is reflected in the transaction log and the log must be accessed prior to reading from the disk storage unit. As a result, the user sees changed data when the log is accessed, or if data has not been changed, the log merely directs the computer to the address in the original database storage where unchanged data is stored.
    • 本发明是一种用于修改数据库的计算机系统,该数据库包括修改存储在数据库中的记录的计算机。 在修改数据库中记录的过程中,通过首先检查事务日志中的地址空间,在提交阶段访问磁盘存储单元中的内存位置的地址。 本发明的计算机系统通过提交交易而不锁定读取器来操作。 这是可能的,因为数据库中的任何更改的数据都反映在事务日志中,并且在从磁盘存储单元读取之前必须访问日志。 因此,当访问日志时,用户看到已更改的数据,或者数据未被更改时,日志只会将计算机指向原始数据库存储中存储未更改数据的地址。
