Abstract: A system may receive a query configured to access a column in a data table. The data table may be in a flat file in a big data storage format. The system may detect the language type of the query and validate the query against the syntax of the language type. The system may also validate an access permission for data in the data table. The access permission may be stored in a permissions database. The system may generate a temporary table including the column with the temporary table configured to support the language type. The system may execute the query against the temporary table to generate a query result based on the temporary table as though it were the underlying data table. The system may enforce column-level or row-level access permissions by excluding columns or rows from the temporary table.

Abstract: A cluster file system includes a front-end file system comprising a hierarchical storage management application programming interface (API), a back-end file system, and a data mover module arranged between the front-end and back-end file systems and adapted for communication with the hierarchical storage management API of the front-end file system. The data mover module is configured to control movement of data between the front-end file system and the back-end file system responsive to information received via the hierarchical storage management API. For example, in some embodiments, the data mover module splits a given file received from the front-end file system into multiple smaller files for storage in the back-end file system and associates with each of the smaller files a corresponding file extension from a designated namespace to permit reconstruction of the given file upon retrieval of the smaller files from the back-end file system.

Abstract: A method and apparatus for introducing domain-specific data types with associated semantics in an RDF database system using an extensibility framework mechanism. The extensibility framework mechanism allows users to map serialized instance data for a particular user-defined data type to properties of a base data structure associated with the domain-specific data and to map instance data in base data structures to the data's serialized form. The RDF database system may return inferred properties of RDF data stored in domain-specific data types in response to a query on the data. Further, the RDF database system may infer relationships between resources in stored data.

Abstract: Data storage is improved by combining content indexing and data reduction in text-containing files by using common word elimination. Raw data is processed by finding words in selected files, creating an index of found words, and replacing the words in the raw data with pointers to the corresponding words in the index. Each word appears only once in the index. Consequently, the index is relatively small and the procedure is completely reversible. In particular, the index is small relative to other methods because the data is transformed in place, and the transformed data and index are used together to capture the total information about the data.

Abstract: A technique for restoring file systems by applying full and incremental backups together while streaming them from multiple devices provides a faster system restore from a full backup where incremental backups must also be applied. A first storage device streams the full backup while at least one second storage device streams at least one incremental backup. As files are detected in the incremental backup, they are written instead of the corresponding file in the full backup. Incremental backups can be pre-merged to reduce their number to one less than a number of storage devices available to stream the backups, so that the full backup can be streamed along with the pre-merged incremental backup(s) to restore the file system.

Abstract: A DBA may pre-generate database recovery jobs on a convenient schedule at a local site, then recover a database at a disaster recovery site. Archive log files for the database that are generated in the interim between recovery job generation and recovery job execution are automatically incorporated into the recovery job when it executes, extending the recovery point closer to the time of the disruption that triggered the need or desire for recovery.
