Abstract: There is provided a non-transitory machine-readable storage medium encoded with instructions executable by a processor. The machine-readable storage medium comprises a graph database comprising first-level vertices and first-level edges, each first-level edge linking two first-level vertices, wherein each first-level vertex represents an entity and each first-level edge represents a relationship between two entities. The machine-readable storage medium further comprises instructions to: responsive to a generation of a result set for a query on the graph database, add a second-level vertex to the graph database, wherein the second-level vertex represents the result set of the query; and add a second-level edge to the graph database, wherein the second-level edge connects the second-level vertex to a first-level vertex.

Abstract: A method is described in which a first data set, which is represented by a first model, is provided; a second data set, which is represented by a second model, is provided; information relating to a link to be created between the first data set and the second data set is received; a link creation mechanism is selected based on the received information; an equivalence between the first data set and the second data set is determined using the selected link creation mechanism; an equivalence relation is added to the first model based on the determined equivalence; and an equivalence relation is added to the second model based on the determined equivalence.

Abstract: Data items are aggregated based on information relating to a display capability of a display device, to produce aggregated data. The aggregated data is for display in a visualization presented by the display device. Responsive to user selection in the visualization, dynamically created data at a second hierarchical level different from a first hierarchical level of the aggregated data is for display in the visualization.

Abstract: A visual representation of a set of objects of a first type (e.g., a set of resources of a first type) and a net of objects of a second type (e.g., a set of resources of a second type) may be generated. The generated visual representation may include a first linear row of graphical representations of individual ones of the set of objects of the first type and a second linear row of graphical representations of individual ones of the set of objects of the second type that is substantially parallel to the first linear row.
