Abstract: System and method for tracking statistics at the subfile level and transparently placing or migrating inactive or less active blocks of data to other storage devices. Embodiments may provide mechanisms to track statistics at the subfile level of files including, but not limited to, database files, and to transparently place or migrate inactive or less active blocks of data of the files from higher-performing, typically more expensive, storage to lower-performing, typically less expensive, storage, while placing or migrating active blocks of data of the files to higher-performing storage, based on the subfile-level statistics rather than on file-level timestamps. In some embodiments, knowledge of file structure (e.g., database file structure), for example knowledge of database partitions with header blocks and data blocks in databases using data partitioning, may be used to separate more active and less active blocks of data of files onto storage with different performance and/or other characteristics.

Abstract: Images created by one or more image acquisition devices are initially stored in remote data bases at one or more remote or satellite locations and copies of the images are subsequently transferred to a central server at a central storage location over a network and stored in a central data base. A common catalog listing local image files stored at the central data base and remote image files stored at one or more remote data bases is stored at the central location and is accessed by users to search for images. User requests for images associated with local image files result in transfer of the requested images by the central server to the user. User requests for images associated with remote image files are relayed by the central server to the associated remote location, and the requested images are then relayed to the user from the remote location via the central server.

Abstract: After receipt of an instruction (e.g. a database statement), one or more computers specialize an interpreter with the received instruction as constant, to obtain a specialized interpreter that is stored in memory and/or disk. The specialized interpreter is then invoked to execute the received instruction. Depending on the embodiment, the interpreter being specialized may additionally be received and used in binary form without specialization. Specifically, in some embodiments, an identical interpreter is received in two forms: in a binary language specific to the one or more computers and also in a language that is acceptable to a specializer, such as a source language or an intermediate language. The interpreter in the binary language is invoked by default unless a predetermined condition for specialization is met. When the predetermined condition is met, the interpreter in the specializer-acceptable language is specialized by the specializer, and then the specialized interpreter is invoked.

Abstract: Various revisions of encoded data slices stored in a distributed storage system can be time stamped to assist in retrieving desired data revisions. Each of the multiple revisions of the encoded data slices may have the same name, but different revision numbers. An encoded data slice, which is received at a distributed storage unit along with a write command, slice name, and the revision number, is time stamped. The timestamp and revision number are stored in conjunction with the data slice. A desired encoded data slice can be retrieved by sending a read command, slice name, and timeframe to the distributed storage unit. The appropriate encoded data slice can be retrieved by determining which revision number has a timestamp most closely matching the requested timeframe.
