Patent number: 8380748Abstract: Computer-readable media, systems, and methods for building a multidimensional data cube having one or more high-cardinality attributes are described. In embodiments, data is extracted from one or more databases. It is determined that one or more instances of the data are fact data and one or more instances of the data are dimension data. Each member of the fact data is one instance of a dimension and each instance of the dimension data includes an attribute for grouping the fact data. Moreover, in embodiments it is determined that one or more instances of the dimension data are high-cardinality attributes. The one or more high-cardinality attributes are processed with fact data and stored in fact tables on a computer storage medium.Type: GrantFiled: March 5, 2008Date of Patent: February 19, 2013Assignee: Microsoft CorporationInventors: Alexander Berger, Mosha Pasumansky, Amir Netz, Akshai M. Mirchandani, Marius Dumitru, Cristian Petculescu

Patent number: 8229923Abstract: A system and techniques for executing queries of a sparse multidimensional data space in the presence of expressions. A dimension is associated with a set of data references, which reference stored data items. A query expression has dimension or a data reference as an operand. A result space with one or more result dimensions is defined based on the query. A plan is built and executed for retrieving the stored data items associated with the result dimensions, and forming “calculated data items” by evaluating the expression. Executing the plan produces a stream of data tuples, each having a set of data components storing the retrieved data items and/or the calculated data items. Data components are either empty or have data values. An iterative algorithm is employed on the stream to locate the data tuples that are empty at the intersection of each result dimension.Type: GrantFiled: September 26, 2008Date of Patent: July 24, 2012Assignee: Microsoft CorporationInventors: Akshai M. Mirchandani, Marius Dumitru, Mosha Pasumansky, Irina G. Gorbach

Patent number: 7886289Abstract: Systems and methods that supply extensibility mechanisms for analysis services, via a plug-in component that enables additional functionalities. The plug-in component provide additional custom logic for the analysis services unified dimensional model (UDM). Accordingly, server functionalities can be extended in an agile manner, and without a requirement for a new release, for example.Type: GrantFiled: March 20, 2007Date of Patent: February 8, 2011Assignee: Microsoft CorporationInventors: Thulusalamatom K. Anand, Paul J. Sanders, Richard R. Tkachuk, Cristian Petculescu, Chu Xu, Akshai M. Mirchandani, Valeri Kim, Andriy Garbuzov, C. James MacLennan, Marius Dumitru, Ioan Bogdan Crivat

Patent number: 7809678Abstract: 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.Type: GrantFiled: May 24, 2005Date of Patent: October 5, 2010Assignee: Microsoft CorporationInventors: Alexander Berger, Edward Melomed, Amir Netz, Cristian Petculescu, Akshai M.

Patent number: 7689703Abstract: 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.Type: GrantFiled: March 1, 2005Date of Patent: March 30, 2010Assignee: Microsoft CorporationInventors: Mosha Pasumansky, Marius Dumitru, Adrian Dumitrascu, Cristian Petculescu, Akshai M.

Patent number: 7562086Abstract: Custom grouping for dimension members of an On-Line Analytical Processing (OLAP) cube is facilitated by an interface component that receives a grouping from a user. A modification component alters an attribute of a session OLAP data cube or a virtual OLAP multi-dimensional data cube so that the change becomes readily available without the time-consuming delay associated with rebuilding or reprocessing the underlying structure. A data scheme generation component produces a data definition language (DDL) definition of a user defined attribute executed by an execution component to affect the change to a data cube. Custom groupings can provide an intermediate dimension level for drill down and/or drill up or roll-up between a level with few members and a level with numerous members. A separate dimensional attribute or level can be created and a group defined comprising or mapping a set or collection of discrete members.Type: GrantFiled: June 27, 2005Date of Patent: July 14, 2009Assignee: Microsoft CorporationInventors: Akshai M. Mirchandani, Alexander Berger, Thomas P. Conlon, Edward Melomed

Patent number: 7533348Abstract: A calendar customization system comprises an interface component that receives responses to one or more questions relating to a calendar. A execution automatically generates a multi-dimensional structure for the calendar, the structure generated as a function of the responses. For example, the multi-dimensional structure can relate to a Gregorian calendar, a fiscal calendar, a reporting calendar, a manufacturing calendar, and/or an ISO8601 calendar.Type: GrantFiled: February 9, 2005Date of Patent: May 12, 2009Assignee: Microsoft CorporationInventors: Thierry D'Hers, Aleksandar Juric, Akshai M.
