    • A method for obtaining parallel instruction execution (PIE) for frequently used programming operations, such as database record compression or expansion, cryptographic encoding/decoding, page moving, etc., for which a hardware-assist may be provided. These functions can be performed in parallel with CPU processing by a PIE processing facility (PIE-PF). The method is hardware/microcode based and uses software control in supervisory mode. The preferred embodiment is controlled by privileged subsystem software under an operating system, and does not use I/O channel oriented off-load processing. When the CPU is interrupted during an incomplete parallel operation by the PIE-PF, it is checkpointed in main storage in a manner accessible to the subsystem. The subsystem (after completing a current CPU operation, such as a database record predicate evaluation, can check for the completion of the PIE-PF operation by examining an indicator in a control block in shared storage. Furthermore, if the parallel operation has not completed, the CPU can: a) continue the PIE-PF processing in parallel with other processing in the CPU, b) halt the parallel PIE-PF asynchronous operation and have the CPU do the rest of the operation synchronously, or c) resume the parallel operation in the processor or a hardware assist if an interruption caused the PIE-PF parallel operation to be checkpointed.
    • 用于获得可以提供硬件辅助的频繁使用的编程操作(诸如数据库记录压缩或扩展,加密编码/解码,页面移动等)的并行指令执行(PIE)的方法。 这些功能可以与PIE处理设备(PIE-PF)的CPU处理并行执行。 该方法是基于硬件/微代码,并以监控模式使用软件控制。 优选实施例由操作系统下的特权子系统软件控制,并且不使用I / O通道定向的卸载处理。 当CPU在PIE-PF的不完全并行操作期间中断时,它将以子系统可访问的方式在主存储中进行检查。 子系统(完成目前的CPU操作,如数据库记录谓词评估)可以通过检查共享存储器中的控制块中的指示符来检查PIE-PF操作的完成情况,此外,如果并行操作未完成 CPU可以:a)与CPU中的其他处理并行执行PIE-PF处理,b)停止并行PIE-PF异步操作,并让CPU同步执行其余操作,或c)恢复并行 如果中断导致PIE-PF并行操作被检查点,则处理器中的操作或硬件辅助。

    • A client-server relational database system, wherein data from the client computer is encrypted by the client computer and hosted by the server computer, the encrypted data is operated upon by the server computer, using one or more operators selected from a group of operators comprising: (a) inequality logic operators, (b) aggregation operators, and (c) wildcard matching operators, to produce an intermediate results set, the intermediate results set is sent from the server computer to the client computer, and the intermediate results set is decrypted and filtered by the client computer to produce actual results. The group of operators is limited because the encrypted results set, when decrypted, includes inaccuracies therein. The client computer applies a set of correction procedures to the decrypted results set to remove the inaccuracies therein.

    • A method and system for providing a database as a is disclosed. In a first aspect, the method comprises the steps of accessing the database over a public network by a browser without downloading software. The method further includes controlling access to the database on an agreed-upon schedule. In a second aspect, a database service for use on a public network is disclosed. The database service comprises a presentation layer, the presentation layer including a browser, a web server coupled to the public network and a web application platform coupled to the web server. The database includes an application layer comprising a user interface (UI) application. The UI application is executed on the web application platform and is capable of communicating with the browser through a standard program code. Finally, the database service includes a database management layer. The database management layer includes at least one database which communicates with the UI application. Accordingly, a database can be managed centrally while resources of the database can be consumed individually and globally.

    • A method, apparatus, and article of manufacture for a computer implemented scaleable set-oriented classifier. The scalable set-oriented classifier stores set-oriented data as a table in a relational database. The table is comprised of rows having attributes. The scalable set-oriented classifier classifies the rows by building a classification tree. The scalable set-oriented classifier determines a gini index value for each split value of each attribute for each node that can be partitioned in the classification tree. The scalable set-oriented classifier selects an attribute and a split value for each node that can be partitioned based on the determined gini index value corresponding to the split value. Then, the scalable set-oriented classifier grows the classification tree by another level based on the selected attribute and split value for each node. The scalable set-oriented classifier repeats this process until each row of the table has been classified in the classification tree.
