摘要： Techniques are described for processing a query to produce query results, the query specifying at least a first timestamp value. Embodiments receive the query for processing and access a database index containing a plurality of database keys. The database index contains one or more database index keys, each of which includes at least a timestamp value and a time zone value. Embodiments compare the first timestamp value specified in the query with a portion of one the database index keys to locate at least a portion of the query results. More specifically, the compared portion of the database index key excludes the time zone value. The located portion of the query results is then retrieved.

摘要： A method and system for efficiently identifying materialized view candidates for queries filters materialized views using certain criteria, using the materialized view signatures. This filtering rejects some of the unqualified materialized views prior to the performance of the query rewrite matching algorithm, resulting in a group of materialized view candidates. The query rewrite matching algorithm is then performed on the materialized view candidates. By first filtering the materialized views based on their signatures, the number of materialized views on which the query rewrite matching algorithm is performed is significantly reduced, improving performance.

摘要： A system and method is provided for query processing comprises: creating an index of a database and ordering a set of index candidates from the index into a list based on a set of heuristic rules. A query defining a query path is then reduced into a list of single path expressions. Each index candidate is matched against the list of single path expressions according to the ordering of the index candidates. The matched candidate nodes are also verified to insure that they satisfy the query path.

摘要： Various aspects of this disclosure are directed to receiving, by a computing device, a first table join query that may include a first group of table identifiers that identify the two or more tables. The computing device may determine whether the first table join query includes an outer join command. When the first table join query includes the outer join command, the computing device may compare the first group of table identifiers and a second group of table identifiers of one or more pre-joined tables to determine whether each of the first table identifiers matches at least one of the second group of table identifiers. The computing device may further determine whether a predicate associated with each table identifier matches a predicate associated with a matching second table identifier. When each of the predicates match, the computing device may rewrite the first table join query.

摘要： A method of detecting and analyzing abnormalities, like lung nodules, in thoracic computer tomography (CT) images uses digital image processing techniques and adaptive computing methods. The techniques include an automatic detection process to detect candidate abnormalities, an image matching process to match CT slices from two different CT scans, and a measurement process that determines parameters of the candidate abnormalities. Final results and processed CT images are displayed on a user interface.

摘要： A method for identifying the orientation of a radiographic image of a patient generates a reduced-scale image having a smaller number of pixel elements than the original radiographic image and generates a reduced bit-depth image from the reduced-scale image. The method determines whether the image has portrait or landscape orientation by sectioning either the reduced-scale image or the reduced bit-depth image into at least two sections and calculating at least one value related to relative symmetry for each of the at least two sections.
