摘要： In one aspect, in general, a method of generating a dataflow graph representing a database query includes receiving a query plan from a plan generator, the query plan representing operations for executing a database query on at least one input representing a source of data, producing a dataflow graph from the query plan, wherein the dataflow graph includes at least one node that represents at least one operation represented by the query plan, and includes at least one link that represents at least one dataflow associated with the query plan, and altering one or more components of the dataflow graph based on at least one characteristic of the at least one input representing the source of data.

摘要： A querying method for a database of graph data encoded as triples being stored on storage servers. The method including dividing a query into a plurality of result criteria triple patterns which query results match, each triple pattern element being either: a single value triple pattern element; or a variable value triple pattern element specifying an ID of a variable. The method includes forming one or more sub-queries each having triple patterns having the same single value triple pattern element or specifying the same ID of a variable as a variable value triple pattern element, issuing each formed sub-query to each of the servers, and receiving triples satisfying a sub-query as results from the servers and using the sub-query results in as a response to the query.

摘要： Methods and systems for use in validating input data in a computing system. Input data associated with a destination software application, such as a database, is received at a computing system. The input data is forwarded to an intermediate software application, such as a web application. When the input includes one or more patterns, a query produced by the intermediate software application based on the input data is validated, such as by comparing the structure of the query to one or more expected query structures. If the validation succeeds, the query is forwarded to the destination software application. Otherwise, the query is discarded.

摘要： The present invention relates to computer implemented methods and system for creating and executing an query plan for SPARQL Protocol And Query Language (SPARQL) queries. The methods and systems are designed to accept as input a query in SPARQL syntax, convert this query to semQA2 and generate a parse tree, perform filter pushdown, generate an efficient query plan potentially using a cost function, and execute this query plan against data sources complying to or modeled as Resource Description Framework (RDF). The result of these methods and of the systems implementing these methods is a set of triples contained in the data sources that comprise a solution of the SPARQL query provided.

摘要： A semantic conversion system (1900) includes a self-learning tool (1902). The self-learning tool (1902) receives input files from legacy data systems (1904). The self-learning tool (1902) includes a conversion processor (1914) that can calculate probabilities associated with candidate conversion terms so as to select an appropriate conversion term. The self-learning tool (1902) provides a fully attributed and normalized data set (1908).

摘要： Systems and methods are provided for performing a database query. After receiving an identification of data item components and associations between the data item components, wherein the data item components include a measure and a category, a query generation system creates and executes a database query that comprises one or more Uqueries, wherein each Uquery comprises a Mx segment subquery and a U0 segment subquery. The Mx segment subquery is associated with a table that contains the measure, a table that contains columns for a calculated measure, or a correlated table, and the U0 segment subquery is associated with a table that contains the category, a table that contains columns for a calculated category, a dependent measure table, or a dependent filter table. The query generation system can generate a virtual results table by aggregating Uquery results from one Uquery with Uquery results from another Uquery.
