Abstract: A base table temporal row affected by a transaction is timestamped. The temporal row has a row ID. The temporal row in the base table is modified according to the transaction. The row ID for the modified temporal row is associated with an identifier for the transaction in a temporal work table. Upon committing the transaction: the temporal work table is searched to determine the row ID of the temporal row modified by the transaction, and a commit-time is saved into the temporal row identified by the row ID.

Abstract: Techniques for multi-variable analysis at an aggregate level are provided. Two or more datasets having different statistical data distributions and which are not capable of being aggregated are acquired. The values for variables in the two or more datasets are normalized to produce a single integrated dataset of normalized values. The normalized values are then used to produce a demand model that represents and integrates multiple disparate products or services from the two or more datasets into a single demand model.

Abstract: A method, computer program, and database system are disclosed for optimizing a query of a table based on one or more values in one or more columns of the table. The method includes repeating the following steps for a series of rows in the table and optimizing an execution plan for the query based at least in part on a calculated number of rows per unique value. One or more values for the one or more columns are read. The read values are determined to be different from all previously read values in some cases. When the read values are different, the one or more values are recorded in a data structure corresponding to the result of applying a hash function to the one or more values.

Abstract: A vendor is authenticated for use of a retailer's data warehouse and limited access rights are assigned to the vendor for access. The vendor accesses a graphical user interface (GUI) to select an available analysis module for execution against the data warehouse. Schemas are presented in the GUI based on the access rights, and specific schema selections are made by the vendor. The analysis module is then configured and executed against the data warehouse and filtered results are presented to the vendor; the results filtered based on the access rights assigned to the vendor.

Abstract: In one embodiment, a method includes concurrently executing a set of multiple queries, through a processor, to improve a resource usage within a data warehouse system. The method also includes permitting a group of users of the data warehouse system to simultaneously run a set of queries. In addition, the method includes applying a high-concurrency query operator to continuously optimize a large number of concurrent queries for a set of highly concurrent dynamic workloads.

Abstract: A forecast response factor (RF) determines how quickly product demand forecasts should react to recent changes in demand. When a product sales pattern changes (e.g., a sudden increase in product demand), RF is adjusted accordingly to adjust the forecast responsiveness. The present subject matter provides automatic calculation of the RF, based at least in part on the nature of the product sales (autocorrelation) and the status of recent forecasts (bias).

Abstract: A graphical user interface (GUI) tool is presented to a user for interacting with an underlying database. The GUI tool includes a field selection and attribute selections for the field. The user selects a field and an attribute for that field and is presented with a first list of values retrieved from the database for the selected attribute. Next, the user selects a filter for the attribute within the GUI tool and a second reduced list of values is presented to the user within the GUI tool representing the filtered first list of values acquired by applying the filter.

A database message is received from the first source. The database message includes a second value for a second source-identifying parameter. The second value identifies a second source. The second value for the second source-identifying parameter is stored in a log.

Abstract: A temporary computer-stored first-unit intermediate result is generated while executing a first unit of work on a computer-based database management system. The first-unit intermediate result has properties. It is determined that the properties of the first-unit intermediate result are similar to properties of a second-unit intermediate result to be generated for a second unit of work when the second unit of work is executed on the computer-based database management system. In response, the first-unit intermediate result is saved for use in executing the second unit of work.

Abstract: A spatial feature is considered for storage in a database system running on a computer. The spatial feature includes a polygon, P. The polygon includes an outer ring, OR, and the area within the outer ring. The polygon includes an interior ring contained within the polygon. The computer removes the interior ring from the polygon. The computer determines a line along which to split the polygon without regard for the location of the inner ring within the polygon. The computer splits the polygon into two polygons, SP1 and SP2, along the line. The computer applies the interior ring to the two split polygons by invoking a point set difference between the interior ring and the two split polygons. The computer stores the split polygons in the database system on the computer.

A master language data structure houses information in a base language and houses linkages to the information for translations in a plurality of different languages. The information and translations are created, updated, managed, and distributed from the master language data structure on demand.

Abstract: A database system is capable of processing a query and providing a progress indicator of the processing of the query based on at least a first cost factor. Initially, an estimate is set for the first cost factor. During processing of the query, the estimate of the first cost factor is updated to enable refinement of the progress indicator.

Abstract: A method of providing enterprise applications with shared access to a data warehouse. A web service request is issued over a data network from a first client enterprise application to a second server enterprise application. A database query is then constructed at the second server enterprise application. It is then determined whether a response to the web service request will include the results of posing the database query against the data warehouse, or the SQL syntax necessary to pose the query. If the response is to include the results of posing then the second server enterprise application poses the query against the data warehouse and issues the results to the first client enterprise application. If the response to the request is to include the SQL syntax necessary to pose the query, then the second server enterprise application provides the database query syntax to the first client enterprise application.

Abstract: A computer system programmed as a database receives a query Q1. Q1 includes a predicate. The predicate includes a reference to a current timestamp of time TT1. The database has R data structures. The computer system creates a plan, Plan 1, to execute Q1. Plan 1 includes the identification of a first set of data structures, P1, to be accessed in executing Plan 1, at the current timestamp of time TT1. The number of data structures in P1 is less than R. The computer system determines that Plan 1 is valid for a period of time. The computer system stores in a cache Plan 1 and an indication that Plan 1 is valid for the period of time.

Abstract: Embodiments of the present invention provide a database system that is optimized by using hardware acceleration. The system may be implemented in several variations to accommodate a wide range of queries and database sizes. In some embodiments, the system may comprise a host system that is coupled to one or more hardware accelerator components. The host system may execute software or provide an interface for receiving queries. The host system analyzes and parses these queries into tasks. The host system may then select some of the tasks and translate them into machine code instructions, which are executed by one or more hardware accelerator components. The tasks executed by hardware accelerators are generally those tasks that may be repetitive or processing intensive. Such tasks may include, for example, indexing, searching, sorting, table scanning, record filtering, and the like.

Abstract: Techniques are presented for tracking status within object chains. Global objects are associated with unique identifiers and each dependent local object created within the context of a particular global object receives that particular global object's identifier. A unique counter value is maintained for each status type of each global object. The local object facilitates communicating changes in its status using the received global identifier, and the counter values are updated accordingly for the affected global object.

Abstract: A system, method, and computer-readable medium for optimized processing of queries that feature maximum or minimum equality conditions are provided. A table on which the query is applied is scanned a single time. Rows of the table distributed to respective processing modules are scanned by the processing modules. Each processing module maintains identification of any rows distributed to the respective processing module that have attribute values that equal the maximum or minimum attribute value locally identified by the processing module. Subsequently, a global aggregation mechanism is invoked to compute the query result without requiring an additional rescan of the table. Further, the disclosed mechanisms may be extended to compute top N queries featuring maximum or minimum equality conditions.

Abstract: Embodiments of the present invention provide a hardware accelerator that assists a host database system in processing its queries. The hardware accelerator comprises special purpose processing elements that are capable of receiving database query/operation tasks in the form of machine code database instructions, execute them in hardware without software, and return the query/operation result back to the host system. For example, table and column descriptors are embedded in the machine code database instructions. For ease of installation, the hardware accelerators employ a standard interconnect, such as a PCle or HT interconnect. The processing elements implement a novel dataflow design and Inter Macro-Op Communication (IMC) data structures to execute the machine code database instructions. The hardware accelerator may also comprise a relatively large memory to enhance the hardware execution of the query/operation tasks requested.
