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： 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： 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.

摘要： 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.

摘要： Some aspects of the invention provide methods, systems, and computer program products for creating an in-memory physical dictionary for data compression. To that end, in accordance with aspects of the present invention, a new heuristic is defined for converting each of the plurality of logical nodes into a corresponding physical node forming a plurality of physical nodes; then place each of the physical nodes into the physical dictionary while traversing the dictionary tree in descending visit count order. Each physical node is placed in its nearest ascendant's cache-line with sufficient space. If there is no space in any of the ascendant's cache-line, then the physical node is placed into a new cache-line, unless a pre-defined packing threshold has been reached, in which case the physical node is placed in the first available cache-line.

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.
