NCR Corp. - Dayton OH

International Classification:

G06F 17/00

US Classification:

707100, 7071041

Abstract:

A logical data model (LDM) design methodology that utilizes common or shared subject areas, developed for applications across two or more industries, in the design and construction of data warehouse solutions and logical data models for specific customers. The development and use of shared subject areas provides for more effective new LDM development through re-use of common elements and quicker deployment of horizontal applications on all industries.

US Classification:

718103, 707713, 707718, 707720

Abstract:

A database system includes a regulator subsystem that is configured to attempt to satisfy service level goals of multiple workloads that are executing in the database system. The regulator subsystem is configured to monitor execution of a particular request belonging to a particular workload and to assign, at plural event intervals, corresponding priority levels to the particular request based on the monitored execution.

Teradata US, Inc. - Dayton OH

International Classification:

G06F 17/30
G06F 17/00

US Classification:

707609, 707802, 707803

Abstract:

A query is received. It is determined that the query includes an inner join between a parent table and a child table. It is determined that the following relationships exist between the parent table and the child table: referential integrity (“RI”) between a primary key attribute (pk) in the parent table and a foreign key attribute (fk) in the child table, where “attribute” is defined to mean one or more columns, and a temporal relationship constraint (“TRC”) between a period attribute in the parent table and a TRC-attribute in the child table, the TRC-attribute being a date or time attribute. It is determined that the query does not access any attribute in the parent table other than the pk. It is determined that the query specifies an equality predicate of the form pk=fk. It is determined that the query selects a snapshot from the parent using a predicate of the form parent.

Appl. No.:

11/281527

Inventors:

Stephen Brobst - Henderson NV, US

International Classification:

G06F 17/30

US Classification:

707003000

Abstract:

A database-management system (DBMS) initiates execution of an incoming database query according to an initial query-execution plan that identifies an expected path for execution. Then, at some point after execution of the query has begun, the DBMS concludes that execution has not proceeded along the expected path and, in response, chooses an alternative query-execution plan for continued execution of the query.

International Classification:

G06F 16/23
G06F 16/9038
G06F 9/54

Abstract:

An Application Programming Interface (API) processes object storage requests in an object storage format that are received from client applications. A mapper maps the object storage formatted requests into database statements and executes the statements within a database management system. Results returned from the statements are mapped by the mapper to object-storage constructs and provided to the API in object storage format. The object storage formatted requests are provided from the API to the client applications to satisfy the original client applications' requests.
