摘要： Many web applications require access to a relational database. The requirements of such web applications are different from conventional applications that access a database. Web applications need to have selective recoverability and need to have support for different transaction structures, other than the flat transaction structure of conventional database applications, including nested and chained transactions. To achieve this, an interface between the application and database has the following functional features: 1) the interface to the database is connection oriented, i.e., the connection is retained across several invocations of the application; 2) the backend of the interface is long living, i.e., it exists across multiple invocations; 3) state information about a session in progress is maintained, and more specifically, it is distributed between the backend of the interface and the hidden fields of the HTML output document.

摘要： A visual query system, and associated method and computer program product enhance and accelerate content-based querying, and present a new image similarity measure using known or available software applications and hardware components of video compression systems. The present system encodes images as consecutive frames in a video sequence and uses the ratio between the file length of the compressed sequence and the original file length as a distance measure. The system considers the compression ratio to be an estimate of the entropy of the combined images, which can be used to estimate the amount of new information introduced from one image to the other.
摘要翻译：视觉查询系统，相关方法和计算机程序产品增强和加速基于内容的查询，并使用视频压缩系统的已知或可用的软件应用程序和硬件组件呈现新的图像相似性度量。本系统将图像编码为视频序列中的连续帧，并将压缩序列的文件长度与原始文件长度之间的比率用作距离度量。该系统认为压缩比是组合图像熵的估计，可用于估计从一个图像引入到另一个图像的新信息的数量。

摘要： The present invention provides a system and method for utilizing the proximity of keys in sequential or near sequential index probes to avoid complete index tree traversal. Page information from three pages (LAST, PARENT and NEXT) are stored in separate information fields within an Index Lookaside Buffer. The LAST information field contains information on the most recent leaf page accessed during an index probe in a read key or an insert key operation, the PARENT information field contains information on the parent page of the most recently accessed leaf page described in the LAST information field, and the NEXT information field contains information on the most recent leaf page accessed during a fetch-next key or delete key operation. On a subsequent index probe, the LAST, NEXT and PARENT information fields are sequentially analyzed to determine if the search key is contained within the leaf page described by the LAST or NEXT information fields or if the search key is contained within one of the leaf pages pointed to by the parent page described by the PARENT information field. If none of the LAST, NEXT or PARENT information fields identify the leaf page containing the search key then the default root-to-leaf traversal would commence.
摘要翻译：本发明提供一种用于利用顺序或近序列索引探针中的密钥接近以避免完整的索引树遍历的系统和方法。来自三个页面（LAST，PARENT和NEXT）的页面信息存储在索引后备缓冲区中的单独的信息字段中。 LAST信息字段包含在读取键或插入键操作期间在索引探测期间访问的最新叶子页面的信息，PARENT信息字段包含在LAST信息字段中描述的最近访问的叶子页面的父页面上的信息，并且NEXT信息字段包含在获取下一个键或删除键操作期间访问的最新叶子页面的信息。在随后的索引探针中，顺序地分析LAST，NEXT和PARENT信息字段以确定搜索关键字是否包含在由LAST或NEXT信息字段描述的叶子页内，或者如果搜索关键字包含在叶子页之一内由PARENT信息字段描述的父页指向。如果LAST，NEXT或PARENT信息字段中没有一个标识包含搜索关键字的叶子页面，则将开始默认的从根到叶遍历。

摘要： A method, apparatus, and article of manufacture for computer-implemented use of object relational extensions for mining association rules. Data mining is performed by a computer to retrieve data from a data store stored on a data storage device coupled to the computer. A multi-column data store organized using a multi-column data model is received. One of the columns in the multi-column data store represents a transaction, and each of the remaining columns in the multi-column data store represents elements of that transaction. A combination operator is performed to obtain candidate itemsets of data from the multi-column data store, each itemset being a combination of a number of rows of the multi-column data store. Large itemsets of data are generated from the candidate itemsets, wherein each itemset has at least a minimum support. Association rules are generated from the large itemsets of data, wherein each association rule has at least a minimum confidence.

摘要： A method, apparatus, and article of manufacture for optimizing SQL queries in a relational database management system using a vectorized index. The vectorized index represents values in one or more of the columns of a particular table in the relational database. The vectorized index is comprised of a plurality of positions, wherein each of the positions comprises a linear array that represents a value for the specified columns in a corresponding row of the particular table in the relational database. To use the vectorized index, SQL operations are converted to a series of bit-vector operations on that index, where the result of the bit-vector operations is a list of row positions in the table.
