International Classification:

G06F 7/00
G06F 17/00

US Classification:

707638, 707600, 707610, 707624

Abstract:

Methods and apparatus for updating a database using a multi-dimensional data model in which data corresponding to the database are organized in multi-dimensional data blocks. Each data block has summary information associated therewith corresponding to a current state of evolution of the associated data block. Dependency information is maintained in the data model which identifies data dependencies within and among the data blocks. A list of change entries identifies changes made to the data blocks and times at which the changes were made. A request to apply a change entry to a data block is received. The change entry is applied to the data block, including generating a dependency list of data blocks whose data depends directly or indirectly from the updated data block. The data blocks in the dependency list are processed in accordance with a dependency update algorithm to update the data blocks in the dependency list.

JOHN XIAO - Cupertino CA, US

International Classification:

G06F 16/25

G06F 40/18

Abstract:

In accordance with an embodiment, described herein are systems and methods that enable client-side calculation with data provided at a multidimensional or other database server. Data provided at the server in accordance with a server-side model, can be transformed/prepared into a grid, for use with a client-side application, for example a client spreadsheet application. During preparation of the grid, one or more portions of the grid that are identified as client-side dynamic parameters, can be represented as dynamic formulas that are modifiable within the client-side application; while parameters of the server-side model that are outside of the grid can be represented as constant values. The grid provided to the client can be used to perform client-side calculations that allow for rapid calculations in response to changes in the client-side model, without introducing a round-trip performance lag between the client-side and server-side.

Abstract:

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium for searches associated with the enterprise information. In one aspect, a method includes receiving a query from a member of an enterprise; searching an index that includes member information and resources: the resources include entities and entity facts related to the enterprise; the entity facts are identified from the entities; the index includes data defining access privileges to the entities and the entity facts according entity fact access control lists; determining the entity facts that are accessible to the member according to the entity fact access control lists; determining, based on member information and entity facts, search result data including data describing entities and entity facts relevant to the query; and providing search results to the member of the enterprise, the search results including the entities and entity facts determined to be relevant to the query.
