Abstract: In one embodiment, a complex query includes components that are arranged in a hierarchical structure including a first type of filter and a second type of filter and are connected by connectors. The method selects a first data set and selects a second data set for the components. The second data set being generated by processing data in the first data set for the second type of filter and the second data set includes entries describing a result of the processing. The first type of filter is applied to the first data set and the second type of filter to the second data set for the components where the information describing the result is used by the second type of filter to filter entries and first type of filter filters entries based on column values in the first data set. The method combines outputs of the components using the connectors.

Abstract: A data exploring application is defined for communicating with different types of data sources comprising data sets. The data exploring application includes an interface and a back-end module. The interface receives requests for connecting with a data source of a defined type. The type of the data source is associated with specific requirements for establishing the connection. The interface receives requests for exploring a hierarchy of data sets of a selected data source from the connected data sources. The interface communicates with a back-end module of the application to provide data associated with requested hierarchy levels from the hierarchy of the data sets. Based on received responses from the back-end module of the application, browsing and editing options are generated at the interface for receiving a selection of a data set from the hierarchy of data sets of the selected data source.

Abstract: The disclosure generally describes methods, software, and systems, including a method for managing modifications to a document by collaborators. A digital document is identified for collaboration by a first user having ownership privileges for the document. The collaboration is associated with at least one collaborator. A duplicate version of the identified document is provided to each of the identified collaborators. The duplicate versions are monitored for modifications performed by corresponding collaborators. A list of modifications is created that identifies the modifications performed by the corresponding collaborators in the duplicate versions associated with those collaborators. A selection from the list of modifications is received from the first user of at least one modification for incorporation into the identified document. Based on the received selection, the selected at least one modification is merged into the identified document.
