Abstract: A computer-implemented method for determining a query execution plan based on transaction state may include determining that a first set of database values in a database table are in a committed transaction state and that a second set of database values in the database table are in an uncommitted transaction state. In response to the determining, the first set of database values may have a first set of statistics generated and the second set of database values may have a second set of statistics generated. The first and second set of statistics may be for use in determining a query execution plan.

Abstract: A distributed storage system called StorFS that performs distributed data deduplication is described. In an exemplary embodiment, a storage controller server determines if there is duplicative data in a distributed storage system. In this embodiment, the storage controller server determines if an entity is duplicated in the distributed storage system in line with an incoming input/output operation. The storage controller server determines if the entity is duplicated in the distributed storage system by receiving the entity and looking up the entity in a data deduplication table. If the entity exists in the data deduplication table, the storage controller server updates the metadata for the entity to point to the duplicate entity.

Abstract: The MULTI-SOURCE, MULTI-DIMENSIONAL, CROSS-ENTITY, MULTIMEDIA ANALYTICAL MODEL SHARING DATABASE PLATFORM APPARATUSES, METHODS AND SYSTEMS (“AMSDB”) transform data aggregated from various computer resources using AMSDB components into updated entity profiles and/or social graphs. In one implementation, the AMSDB aggregates data records including search results, purchase transaction data, service usage data, service enrollment data, and social data. The AMSDB identifies data field types within the data records and their associated data values. From the data field types and their associated data values, the AMSDB identifies an entity. The AMSDB generates correlations of the entity to other entities identifiable from the data field types and their associated data values. The AMSDB also associates attributes to the entity by drawing inferences related to the entity from the data field types and their associated data values.

Abstract: Techniques for query optimization for group-by extensions and distinct aggregate functions are provided. A query has an extended group-by clause with an extended group-by operator and a first set of group-by columns. The query has one or more distinct aggregate functions and one or more non-distinct aggregate functions. An initial subquery is constructed that generates a partially aggregated initial temporary (PAIT) table when executed. The initial subquery includes a GROUP BY clause with a second set of group-by columns that includes the first set of group-by columns of the extended group-by clause of the query and one or more columns specified by the one or more distinct aggregate functions. One or more subqueries are computed that compute groupings indicated by the extended group-by operator based on the PAIT table generated by the initial subquery.

Abstract: This disclosure is directed to automated methods and systems for calculating hard thresholds used to monitor time-series data generated by data-generating entity. The methods are based on determining a cumulative distribution that characterizes the probability that data values of time-series data generated by the data-generating entity violate a hard threshold. The hard threshold is calculated as an inverse of the cumulative distribution based on a user defined risk confidence level. The hard threshold may then be used to generate alerts when time-series data generated later by the data-generating entity violate the hard threshold.

Abstract: A data management apparatus is provided. In the data management apparatus, a real-time database stores data collected from a power system; a power system data recording (PSDR) server reads and stores data stored in the real time database and creates policy data and a data file on the basis of the stored data and a PSDR history file storage unit backs up data processed by the PSDR server.

Abstract: A method and system for fuzzy full text search is disclosed. The system includes an inverted index where tokens are organized in a Next Valid Character (NVC) tree. Each path through the tree defines a token. The document lists for the tokens are stored at leaf nodes. When performing a fuzzy full text search, the system uses an edit distance greater than zero. After receiving search tokens, the system traverses the NVC tree to generate document error lists. The system then compares the error lists to identify relevant document identifiers and provides a result set.

Abstract: Technologies are described herein for executing queries expressed with reference to a structured query language against unstructured data. A user issues a structured query through a traditional structured data management (“SDM”) application. Upon receiving the structured query, an SDM driver analyzes the structured query and extracts a data structure from the unstructured data, if necessary. The structured query is then converted to an unstructured query based on the extracted data structure. The converted unstructured query may then be executed against the unstructured data. Results from the query are reorganized into structured data utilizing the extracted data structure and are then presented to the user through the SDM application.
