摘要： Embodiments relate to data archiving utilizing an existing big data platform (e.g., HADOOP) as a cost-effective target infrastructure for storage. Particular embodiments construct a logical structure (hereafter, "vault") in the big data platform so that a source, type, and context of the data is maintained, and metadata can be added to aid searching for snapshots according to a given time, version, and other considerations. A vaulting process transforms relationally stored data in an object view to allow for object-based retrieval or object-wise operations (such as destruction due to legal data privacy reasons), and provide references to also store unstructured data (e.g., sensor data, documents, streams) as attachments. A legacy archive extractor provides extraction services for existing archives, so that extracted information is stored in the same vault. This allows for cross queries over legacy data and data from other sources, facilitating the application of new analysis techniques by data scientists.

摘要： The present disclosure relates to a method for securing access to a first relation. The first relation comprises data items. The data items form a partially ordered set in the first relation. The method comprises: predefining a reference data item; creating a relation and inserting a given data item of the set of data items into the relation; inserting each data item of the set of data items into the created relation using the traversal method, wherein the order comparing step comprises in case a comparison result of the currently traversed data item with the reference data item is different from a comparison result of the to be inserted data item with the reference data item inverting the decision logic, and using the inverted decision logic in the decision step; and providing the created relation.

摘要： The techniques introduced here provide for enabling deduplication operations for a file system without significantly affecting read performance of the file system due to fragmentation of the data sets in the file system. The techniques include determining, by a storage server that hosts the file system, a level of fragmentation that would be introduced to a data set stored in the file system as a result of performing a deduplication operation on the data set. The storage server then compares the level of fragmentation with a threshold value and determines whether to perform the deduplication operation based on a result of comparing the level of fragmentation with the threshold value. The threshold value represents an acceptable level of fragmentation in the data sets of the file system.

摘要： A computerized system including a processor and a computer-readable non-transient memory in communication with the processor, the memory storing instructions that when executed manage a novel data structure and related group of algorithms that can be used as a method for representing a set and as a base for very efficient indexing, hash and compression. SHB is an improvement of hierarchical bitmap. An improved database system that can utilize the innovative data structure which includes a raw data stream provided to the system via a data processing module, data blocks, fields indexes tables and a keys table. There is provided an index creating process and a columns creating process, for transforming the data blocks and tables into index blocks and data columns.
