Abstract: A rod belt, in particular for rod belt conveyors of agricultural machines, the rod belt having a running direction and comprising: tensile stress-resistant, elastic and continuous belts running in parallel to one another; transverse rods arranged perpendicular to the running direction and parallel to one another in a pre-determined rod spacing, each transverse rod having mounting sections with which the transverse rods rests on the belts, wherein the transverse rods are fastened to the belts by attachment means, passing through the mounting sections of the transverse rods and the belts; and protective forge covers attached to the belts, each forge cover having a mounting profile and a flexible protection profile.

Abstract: Metadata can be provided to multiple processing units of a database system by using local storages respectively provided for the processing units, such that a local storage is accessible only to its respective processing unit. As a result, processing units can access metadata when needed (e.g., when needed to process a database request at runtime) without having to access a source external to the database system. In addition, metadata (e.g., an XML object, XML schema, XSLT stylesheets, XQuery modules) can be provided using a database request or command, for example, by using a register statement.

Abstract: Apparatus, systems, and methods may operate to receive a request to move at least a portion of a database table stored on a tangible medium from a current partition to a history partition, wherein the database table is partitioned into physical partitions according to a selected mapping update frequency. In response to receiving the request, activities may include modifying a logical partitioning of the database table by updating a mapping of the physical partitions to logical partitions. Other apparatus, systems, and methods are disclosed.

Abstract: Apparatus, systems, and methods may operate to receive requests to execute a plurality of compression and/or decompression mechanisms on one or more database objects; to execute each of the compression and/or decompression mechanisms, on a sampled basis, on the database objects; to determine comparative performance characteristics associated with each of the compression and/or decompression mechanisms; and to record at least some of the performance characteristics and/or derivative characteristics derived from the performance characteristics in a performance summary table. The table may be published to a storage medium or a display screen. Other apparatus, systems, and methods are disclosed.

Abstract: A temporal target table stored on a computer is scanned using the computer. The temporal target table has a ValidTime dimension and a value dimension. A qualifying-row having a value dimension having a value equal to a value of a value dimension in a row-to-be-inserted is found during the scanning. The row-to-be-inserted has a ValidTime dimension and the value dimension. The qualifying-row is processed. The row-to-be-inserted is inserted in the temporal target table. A ValidTime dimension of the inserted row-to-be-inserted is set to be as the union of the ValidTime dimension of the row-to-be-inserted and the ValidTime dimension of the qualifying-row.

Abstract: Apparatus, systems, and methods may operate to receive a set of ordered user-selected compression rules as a compression rule set comprising at least one compression threshold condition, to create or transform a database object with rows to be selectively compressed according to the compression rules in the compression rule set (providing a transformed object), and to publish at least a portion of the transformed object to one of a storage medium or a display screen. Other apparatus, systems, and methods are disclosed.

Abstract: Techniques for constructing and using run-time JAVA Archive (JAR) files for JAVA Stored Procedures (JSPs) are provided. JSP methods referenced by an application via a plurality of different JAR files are extracted and packed into a single packed JAR file. When the application tries to execute a JSP, the attempt to process the JSP methods is redirected to a new JSP that calls the single packed JAR file.

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.

Abstract: Apparatus, systems, and methods may operate to retrieve multiple rows of a database in response to receiving a request to execute an aggregate user defined function (UDF) over the multiple rows, to sort each of the multiple rows into common groups, grouping together individual ones of the multiple rows that share one of the common groups, and to send UDF execution requests to apply the aggregate UDF to aggregate buffers of the common groups to produce an aggregate result, so that one of the UDF execution requests and one context switch are used to process each of the aggregate buffers used within one of the groups to provide at least one intermediate result that can be processed to form the aggregate result. Other apparatus, systems, and methods are disclosed.

Abstract: A cargo carrier assembly for use with a pickup truck or other cargo-carrying vehicle includes a movable tray for the bed of the pickup truck. The carriage includes wheels to roll along the bed between a storage/transit position within the bed when the tailgate is up or down, and an access/loading position on top of the tailgate when the tailgate is down. Also, there are retainer assemblies for retaining the tray in the stored position, as well as in the access position.
