    • A system and method of retrieving data from a database comprising unstructured data comprises specifying a text analytic component in an unstructured text query at query runtime; submitting the unstructured text query to a web service database; filtering unstructured text data in the web service database based on constraints defined in the text analytic component in the query; and receiving the filtered unstructured text data based on the submitted query from the web service database, wherein the text analytic component comprises metadata requirements. Preferably, the constraints comprise any of positive sentiments regarding an unstructured text document and negative sentiments regarding the unstructured text document. Alternatively, the constraints may comprise any of name spotting constraints, address spotting constraints, date spotting constraints, and entity spotting constraints. The filtering preferably occurs using a web-based callback service specified in a WFQL XML document. The database is preferably run on a WebFountain platform.
    • 从包括非结构化数据的数据库检索数据的系统和方法包括在查询运行时指定非结构化文本查询中的文本分析组件; 将非结构化文本查询提交到Web服务数据库; 基于查询中文本分析组件中定义的约束,过滤Web服务数据库中的非结构化文本数据; 以及基于从所述Web服务数据库提交的查询接收所述经过过滤的非结构化文本数据,其中所述文本分析组件包括元数据要求。 优选地,约束包括关于非结构化文本文档的任何正面情绪以及关于非结构化文本文档的消极情绪。 或者,约束可以包括任何名称检测约束,地址检测约束,日期检测约束和实体检测约束。 过滤优先使用WFQL XML文档中指定的基于Web的回调服务进行。 数据库最好在WebFountain平台上运行。

    • A database management system and associated methods for parallelizing file archival and retrieval in an extended database management system. The system includes a set of copy agents that selectively acquire the backup tasks from a copy queue, and a set of retrieval agents that selectively acquire the restore tasks from a restore queue. The chances of contention between any two copy agents or any two retrieve agents acquiring the same copy or restore task is significantly minimized. Once specific copy agents are assigned backup tasks, the backup process is implemented to determine the optimal way to write the backup files to one or more targets, in parallel. In addition, the present system enables the efficient and expeditious retrieval of the desired files without having to search all the targets.
    • 一种用于在扩展数据库管理系统中并行化文件归档和检索的数据库管理系统和相关方法。 该系统包括一组从代理队列选择性地获取备​​份任务的复制代理,以及一组从还原队列中选择性地获取还原任务的检索代理。 任何两个复制代理或获取相同复制或还原任务的任何两个检索代理之间的竞争机会显着地最小化。 一旦为特定的副本代理分配备份任务,则实施备份过程以确定并行将备份文件写入一个或多个目标的最佳方式。 此外,本系统能够有效和快速地检索所需文件,而无需搜索所有目标。

    • Recovery of a filesystem directory structure is performed to restore it to any point in time and also to synchronize a database restore and a filesystem restore to bring the two restores to a database consistent state. A database management system (DBMS) manages external files and hierarchical directory structures to enable recovery and reconciliation of the files and filesystems, under DBMS control, after filesystem crashes. First, a database table, which recorded previous directory creations and deletions, is used to rebuild a filesystem's directory structure to any previous database state and then external file link information is used to restore files to that same state.
    • 执行文件系统目录结构的恢复,以将其还原到任何时间点,并且还可以同步数据库还原和文件系统还原,以使两个还原到数据库一致状态。 数据库管理系统(DBMS)管理外部文件和分层目录结构,以在文件系统崩溃后,在DBMS控制下启用文件和文件系统的恢复和协调。 首先,记录以前的目录创建和删除的数据库表用于将文件系统的目录结构重建为任何先前的数据库状态,然后使用外部文件链接信息将文件还原到同一状态。
