Abstract:

In parallel database management systems, database update requests typically result in activity at several nodes. Rollback of all updates is required if the update of any node fails. A coordination process monitors for failure or success of updates. The coordinator further provides for distinguishing activities that have taken place at any given node from the other nodes for different database update requests. Savepoints are local. This allows rollback of a selected update without affecting nodes which did not process the update.

Abstract:

The present invention provides an evaluation strategy for the execution of SQL queries involving recursion and table queues in a relational database management system. The table queue is established for the query in the memory of the computer, and tuples are generated by tuple-producing operators in the query for storage into the table queue. As operators of the query read the stored tuples from the table queue, a first end-of-file condition, termed a Temporary End-Of-File, occurs when all of the tuples currently stored in the table queue have been retrieved and control is returned to the operator reading from the table queue. A retry request for additional tuples is generated by the operator through the table queue to the tuple-producing operators. If the tuple-producing operators can generate additional tuples, then these additional tuples are stored into the table queue and control is returned to the operator reading from the table queue in response to the retry request. If the tuple-producing operators cannot generate the additional tuples, then a second end-of-file condition, termed a Permanent End-Of-File, occurs and control is returned to the operator reading from the table queue.

US Classification:

395500

Abstract:

The invention establishes the context in which data exchanged between dissimilar relational database management systems can be mutually understood and preserved, and data conversions can be minimized. The invention accomplishes this by establishing layers of descriptive information which isolate machine characteristics, levels of support software, and user data descriptions. Optimized processing is achieved by processing the different descriptor levels at different times during the development and execution of the database management systems. Minimal descriptive information is exchanged between the cooperating database management systems. Any data conversions that may be necessary are done only by the receiver of the data, and only at the point where it is necessary to have the data represented in the receiver's native format for processing. For sending and receiving systems which match, data conversion is completely avoided, even when the data may have been forwarded through intermediate DBMS systems which do not match. For sending and receiving systems which do not match, data conversion is minimized.

Abstract:

A biostimulator transport system, such as a biostimulator delivery system, having a swaged torque shaft, is described. The torque shaft includes an outer cable coaxially arranged with an inner coil. The inner coil has a single wire coil extending around a central axis in a first helical direction, and the outer cable has several outer strands that extend around the central axis in a second helical direction that is different than the first helical direction. The outer cable can be swaged to form a close fit to the inner coil. The close fit of the swaged coaxial torque shaft structure can track to a target site through tortuous vessels and efficiently transfer torque from a handle to a docking cap of the biostimulator transport system to drive a biostimulator into the target site. Other embodiments are also described and claimed.
