Data retrieval from data sources associated with elements of a scorecard is optimized by combining the queries for the same data sources into a single query. The querying process is further optimized based on an attribute and/or condition of a data source. Query parameters and execution schedule may be adjusted based on the elements, data sources, or subscriber identity. Retrieved data is cached at element, combination of elements, data source, or scorecard level for rapid and efficient building and maintenance of scorecards.
