1. A system including instructions recorded on a non-transitory computer-readable storage medium, and executable by at least one processor, the system comprising: a query relationship data structure (RELSTRUCT) generator configured to cause the at least one processor to select a plurality of queries, each query structured for repeated application against a database to yield a query result that is updated over time with each repeated application, the RELSTRUCT generator including a query analyzer configured to cause the at least one processor to identify query parts of individual queries, and determine for each query, a relation, if any, of an included query part to any query part of remaining queries of the plurality of queries; wherein the RELSTRUCT generator is further configured to cause the at least one processor to create, for each query, a query relationship data structure (RELSTRUCT) in which the query is related to at least one other query of the plurality of queries, based on the determined relation of a query part of the query and a query part of the at least one other query of the plurality of queries, and store the query relationship data structures in a query relationship data structure (RELSTRUCT) repository, and further wherein the RELSTRUCT generator is further configured to cause the at least one processor to calculate, for a first query and a second query of the plurality of queries, a dependency between a first query result and a second query result thereof, based on the determined relation between the query parts of the first query and the second query as determined from a corresponding RELSTRUCT, and visually display the first query result, the second query result, and the dependency therebetween, including maintaining the dependency with each repeated application of the first query and the second query, using the stored, corresponding RELSTRUCT, wherein the first query result includes a first Key Performance Indicator (KPI) representing a state or value for an entity in a business context, and the second query result includes a second KPI.
