摘要:
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.

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.

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.

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.

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.

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.

Provided are systems and methods that facilitate direct write back in a multi-dimensional database. The system includes a delta cache component that receives a user request to change an original cell value and determines a delta value based at least in part upon the changed cell value. Also included is a write back partition component that selectively updates a data cell based at least in part upon the delta value without updating corresponding data cell values. The system and methods allow attributes to be added to any dimension of a cube without affecting the write back data. Adding, modifying or removing a hierarchy has no affect on write back data nor does deleting a dimension that is not referenced by a write back.

A system that facilitates generating a report based upon data within a relational database comprises a mapping component that utilizes mapping functions to associate a multi-dimensional structure with the relational database. A report generator communicates with the multi-dimensional structure to obtain data relating to the relational database and generates a report that includes the obtained data. For example, the mapping component can utilize measure groups to effectuate the association between the multi-dimensional structure and the relational database.

A measure expression may include a relationship between measures defined by an arithmetic operation. A query may request a calculation of the measure expression over a selected range of attributes. The request may be processed by retrieving all rows comprising data within the selected range of attributes for each measure in the expression through a single access to an associated table.
