Abstract: According to embodiments of the present invention, machines, systems, computer-implemented methods and computer program products are provided for converting part or all of a document from an unstructured format into a structured format, and combining structured and unstructured data into an unstructured format. In some embodiments, documents are received in an unstructured format, and stored in a repository for querying (e.g., including updating and other operations (e.g., SQL SELECT, UPDATE, INSERT, DELETE, MERGE, etc.)). Responsive to detecting a predetermined number of the documents in an unstructured format stored in a repository for querying, an optimization criteria may be applied to identify one or more components of the stored documents for conversion, and the one or more components of the stored documents are converted from the unstructured format to a structured format.

Abstract: Provided are techniques for cyclic based data partitioning policy with automatic physical schema management. A data partitioning policy for data is received, wherein the data partitioning policy identifies a condition for automatically implementing the data partitioning policy and criteria for modifying a set of partitions. In response to the condition occurring, the data partitioning policy is automatically applied to select at least one partition from the set of partitions based on the criteria. An operation is performed on the at least one partition to modify the set of partitions.

Abstract: Provided are techniques for building an undo log for in-memory blocks of data. Permission on a block of data in memory is set to prevent updates to that block of data using a memory protection function. In response to an update operation attempting to update the block of data in the memory, an interrupt with a location of the block of data is received, the block of data is copied to an undo log entry in an undo log, and the permission on the block of data in the memory is set to allow the update to that block of data to proceed using the memory protection function.

Abstract: A device is provided that includes a flexible elongated member and a spiral member. The spiral member is engaged with at least a portion of the flexible elongated member. The spiral member asserts a biasing force on the flexible elongated member to prevent the flexible elongated member from becoming tangled.
