Abstract: A system includes identification of dimension filters associated with a visualization, identification, from the identified dimension filters, of nested dimension filters associated with a first dimension, generation of a composite filter based on the identified nested dimension filters, transmission of a query to a data source, the query including the composite filter, reception of a result set based on the query from the data source, and display of the visualization presenting the result set on the display.

Abstract: In in-memory workspace management, a request is received from a user to open a document. It is determined whether the document is opened. Upon determining that the document is already opened, an existing workspace instance corresponding to the opened document is shared with the user. A mapping between the workspace request identifier and a workspace identifier is maintained in a workspace map. A reference count mapped to the workspace identifier is incremented since the existing workspace instance is shared with the user. It is determined whether the document is edited. The shared workspace instance is discontinued from sharing and is forked to create a new workspace instance for editing. The mapping between workspace request identifier and workspace identifier is removed from the workspace map. The reference count map is updated to decrement the reference count corresponding to the workspace identifier.

Abstract: A workflow execution framework is generated to execute a received workflow. The workflow is semantically analyzed to determine workflow chain and associated workflow components. To execute the workflow chain, a terminal component in the workflow chain and a corresponding sequential hierarchy of the workflow components are detected. A result descriptor of a data source component corresponding to the terminal component is computed and stored in an execution state table. Result descriptors are computed for the workflow components succeeding the data source component in the sequential hierarchy and are stored in the execution state table. Upon detecting a dataflow between the data source component and one of the succeeding workflow components, data along each row of the execution state table is extracted to process the one of the succeeding workflow components. The workflow is executed by processing the workflow components associated with the workflow chain, thereby executing the workflow chain.

Abstract: Various embodiments of systems and methods for performing predictive analysis are described herein. In one aspect, the method includes receiving a command for publishing a chain comprising a plurality of components connected together to perform predictive analysis. Based upon the command, a plurality of procedures corresponding to the plurality of components of the chain is generated. The generated procedures are integrated according to an order of connectivity of the components within the chain. A database object including the integrated procedures is generated. The database object is stored within a database. The stored database object is executable for performing predictive analysis.

Abstract: A system and method for dynamic generation of contextual charts for reports based on personalized visualization preferences are described. In one embodiment, a system of an embodiment creates a chart for a report based on an analysis of past user preferences. In one embodiment, a system of the embodiment saves user behavior and preferences over time.
