Appl. No.:

12/962429

International Classification:

G06F 17/30

US Classification:

707746, 707741, 707E17002

Abstract:

Secondary indexing mechanisms are disclosed. A first index is created in a database environment. The index has a scope defined by a set of files that meet a pre-selected criteria. Second index generation is initiated. Te second index has the same scope as the first index. A first time period between initiation of the generation of the second index and completion of the second index is determined. The second index is swapped with the first index in an atomic swap operation. The indices may be generated for a multitenant database environment. Catch up indexing may be performed for the secondary index.

Chenghung KER - Burlingame CA, US
Danil DVINOV - San Francisco CA, US
David HACKER - Arlington VA, US

International Classification:

G06F 17/30

Abstract:

Some embodiments of the present invention include a method for identifying match candidates in a database object and may include generating, by a database system, a match key associated with a lookup field of a database object. The method may further include activating, by the database system, a matching rule associated with the match key, and receiving, by the database system, a request to search for duplicate candidates in the database object. The request may include an input entity. The duplicate candidates in the database object may be identified by using the input entity and the matching rule.

International Classification:

G06F 17/30

Abstract:

Matching objects using keys based on match rules is described. A system generates a match rule key based on a match rule, wherein the match rule specifies whether two objects match. The system creates candidate keys by applying the match rule key to data objects. The system creates a probe key by applying the match rule key to a probe object. The system determines whether the probe key matches a candidate key. The system determines whether the probe object matches a candidate object based on applying the match rule to the probe object and the candidate object if the probe key matches the candidate key corresponding to the candidate object. The system identifies the probe object and the candidate object as matching based on the match rule if the probe object matches the candidate object.
