摘要： A method, apparatus, and article of manufacture for providing transaction control for a computer-implemented database management system. The database management system manages one or more databases, wherein each of the databases contains one or more documents and each document contains one or more objects. The database management system also supports a file cache for those databases. A transaction control system provides transaction control for the databases, documents, and objects managed by the database management system, wherein the transaction control system monitors and controls the file cache to ensure that modified objects are stored on a data storage device in manner that reflects an accurate status for a log file maintained by the transaction control system.

摘要： A method, system, business method, and computer program product for retrieving and organizing networked data, wherein fetch rules and extraction rules enable a user to automatically collect and extract information from a remote network site. The fetch rules reproduce the interaction a client executes if interacting directly with the remote site, so a server cannot be shut out. The extraction rules allow the client, preferably via an applet, to glean relevant information from the acquired pages for presentation in a general interface. As an electronic commerce business method, information about remote site responsiveness, fetch rules, and extraction rules may be shared between server and client for a fee. The server accumulates vendor contacts, stores query rules, and provides common interface rules. The invention can gather statistics on vendor responsiveness and can resell information to vendors or others.
摘要翻译：一种用于检索和组织网络数据的方法，系统，业务方法和计算机程序产品，其中获取规则和提取规则使得用户能够从远程网站自动收集和提取信息。获取规则重现客户端直接与远程站点交互时执行的交互，因此无法关闭服务器。提取规则允许客户端，优选地通过小应用程序从所获取的页面中收集相关信息，以便在通用接口中呈现。作为电子商务业务方法，有关远程站点响应，获取规则和提取规则的信息可能会在服务器和客户端之间共享一段费用。服务器累积供应商联系人，存储查询规则，并提供通用接口规则。本发明可以收集关于供应商响应能力的统计信息，并可以向供应商或其他人转售信息。

摘要： A method, apparatus and article of manufacture, implementing the method, of determines a target data type in an environment having a plurality of levels. Zero or more intermediate levels are between the source level and the target level. A target data type representing the transformation of a data type of an associated datum as the datum passes from the source level through the zero or more intermediate levels to the target level is generated. In another aspect of the invention, the datum is assigned to the target level in accordance with the target data type. In yet another aspect of the invention, the target data type is passed with the associated datum, via the zero or more intermediate levels to the target level.

摘要： A database including vertical tables useful for storing large numbers of objects having potentially thousands of attributes in, e.g., e-commerce applications. To support querying the vertical database using conventional SQL, a horizontal view over the underlying vertical tables is defined, and then queries are posed against the view. The queries are automatically transformed and executed against the vertical tables. If desired, the query results can be transformed back to a horizontal format. In this way, it appears to the user that a conventional horizontal data format is being used.

摘要： In a multiprocessing system, multiple concurrently operating task execution units are operated to perform an aggregate task by using incremental and on-demand sub-task allocation. A command is received to perform a machine-executed task divisible into multiple sub-tasks, i.e., an “aggregate task”. A granularity is then established, for dividing the aggregate task into sub-tasks. Preferably, the granularity is not too large to permit potentially uneven sub-task allocation, and not too small to incur excessive overhead in allocating sub-tasks. Having established the granularity, multiple task execution units are independently operated on-demand to sequentially self-allocate and execute sub-tasks of the aggregate tasks. Each sub-task is sized according to the established granularity. Operating “on-demand”, each task execution unit sequentially allocates and executes one sub-task at a time, then proceeding to the next unexecuted sub-task. Thus, the multiprocessing system operates like multiple people drinking water from a common glass through individual straws—although each drinker works independently, all finish simultaneously, thus completing the aggregate task as expeditiously as possible.
摘要翻译：在多处理系统中，通过使用增量和按需子任务分配来操作多个并发操作任务执行单元来执行聚合任务。接收到用于执行可分为多个子任务（即，“聚合任务”）的机器执行任务的命令。然后建立粒度，将聚合任务划分为子任务。优选地，粒度不是太大，不能允许潜在的不均匀的子任务分配，并且不太小，在分配子任务时不会产生过多的开销。建立粒度后，多个任务执行单元按需独立运行，顺序自动分配和执行总任务的子任务。每个子任务的大小根据建立的粒度。每个任务执行单元按“按需”运行，一次顺序分配并执行一个子任务，然后进行到下一个未执行的子任务。因此，多处理系统通过个人吸管，像普通玻璃饮水一样运作，虽然每个饮酒者独立工作，但是同时完成，从而尽可能快地完成总体任务。
