Appl. No.:

11/069121

Inventors:

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 17/30

US Classification:

707 4, 707103 R, 707 2

Abstract:

Architecture that facilitates syntax processing for data mining statements. The system includes a syntax engine that receives as an input a query statement which, for example, is a data mining request. The statement can be generated from many different sources, e. g. , a client application and/or a server application, and requests query processing of a data source (e. g. , a relational database) to return a result set. The syntax engine includes a binding component that converts the query statement into an encapsulated statement in accordance with a predefined grammar. The encapsulated statement includes both data and data operations to be performed on the data of the data source, and which is understood by the data source. An execution component processes the encapsulated statement against the data source to return the desired result set.

International Classification:

G06F 7/00

US Classification:

7071041, 707 3

Abstract:

The subject invention pertains to interaction with multidimensional data. More specifically, interactions can be constrained to a limited subset of a multidimensional data cube, namely a subcube. Subsequent to or concurrently with subcube creation, query execution or other interactions such as calculations can be consolidated or restricted to the smaller subcube query space rather than the typically enormous main cube. Multiple subcubes can also be created and nested to gradually reduce the query space. Deletion of one subcube can cause a reversion back to a previously defined or hierarchical parent subcube.

International Classification:

G06F 17/30

US Classification:

707100, 707 1, 707102, 707200

Abstract:

A data model for accessing data in a relational database in an OLAP system utilizes a multiple-hierarchy dimension. The dimension includes a set of attributes. Each attribute is bound to a column in the relational database. A logical structure is defined, indicating the relationships between the attributes. Hierarchies are defined. Each hierarchy includes a sequence of attributes. A hierarchy provides a common drill-down path that a database user can utilize to access the database. A hierarchy can include a single attribute or a combination of attributes. Both the relationships between the attributes and the sequence of attributes in a hierarchy are defined independent of any restrictions associated with the database.

International Classification:

G06F 7/00
G06F 17/30

US Classification:

707 3, 707100

Abstract:

A system that facilitates one or more of querying and updating a multi-dimensional structure comprises a component that receives a statement in a declarative language relating to a typed object associated with a multi-dimensional structure. A conversion component analyzes context associated with the statement and automatically converts the object to a disparate type as a function of the analysis. For example, an execution engine can comprise the conversion component, and the execution engine can be an Online Analytical Processing (OLAP) engine.

US Classification:

707102, 707 3, 707101

Abstract:

A system that facilitates analyzing content of a multi-dimensional structure comprises a calculation component that receives statements in a declarative language relating to one or more of an assignment and calculation and executes such statements against a multi-dimensional structure. A pass generation component creates a pass in order to maintain content of the multi-dimensional structure as it existed prior to execution of the statement, the pass is accessible upon reference to such pass.

US Classification:

709230, 707 10

Abstract:

The subject invention relates to systems and methods that extend the network data access capabilities of mark-up language protocols. In one aspect, a network data transfer system is provided. The system includes a protocol component that employs a computerized mark-up language to facilitate data interactions between network components, whereby the data interactions were previously limited or based on a statement command associated with the markup language. An extension component operates with the protocol component to support the data transactions, where the extension component supplies at least one other command from the statement command to facilitate the data interactions.

Abstract:

The subject invention pertains to systems and methods that facilitate development and debugging of calculations in a multidimensional data environment or model. Data cube calculation scripts, including those provided in MDX (Multidimensional Expressions), can be executed or applied incrementally. Breakpoints can be set with respect to a calculation script and the cube state can be viewed and queried via a user interface. Users are enabled by the subject systems and methods to step through calculation scripts, identify the effects on a cube, and alter the script if the desired results failed to occur. In addition to debugging, the systems and methods can be employed for initial development of scripts.

US Classification:

707606, 707600, 707605

Abstract:

The subject invention pertains to systems and methods for interacting with fact dimensions. In particular, systems and methods are disclosed that optimize performance and scalability with respect to processing queries that involve fact dimensions. Furthermore, queries involving fact dimensions can be evaluated in distinct manners. For instance, queries can be processed such that regular dimensions restrict the scope of the data and only fact dimension members that are relevant to that scope are exposed.
