Abstract: Arrangements and procedures for arranging peer-to-peer communications sessions between applications are described. In one implementation, a first application executing at a first device utilizes online presence information of an instant messaging service to select a second application with which to engage in the peer-to-peer session. The second application is associated with a second device and registered with the instant messaging service as being peer-to-peer session invite capable. The first application arranges the peer-to-peer session via components of the instant messaging service. The arranged peer-to-peer session is functionally independent of the instant messaging service.

Abstract: An aggregated query is used to fetch data from a multidimensional database, such as an OLAP cube. The aggregated query combines individual queries that are used to fetch data from the multidimensional database into a single query. A determination is made as to what dimensions and hierarchies of the multidimensional database are used by the queries that are contained as cube functions within formulas in cells of a spreadsheet. Based on the dimensions and hierarchies that are used within the multidimensional database, a tuple for each of the individual queries is created that has the same dimensionality. These tuples having the same dimensionality are then combined to create the aggregated query.
