Abstract: Embodiments of the present disclosure relate to a database system for dynamically and automatically accessing and storing data items from multiple data sources. The system may, for example, determine data sources to access, and ways of accessing data items from those data sources, based on an indication of an analysis level and/or other analysis criteria. Further, the system may selectively and efficiently integrate data items from the multiple data sources. Selective integration of data items may be based, for example, on the indication of the analysis level and/or other analysis criteria. The system may further generate outputs of the selective integration of data items. These outputs may, for example, include specialized reports and/or user interfaces. The outputs of the system, in some implementations, may be interactive and dynamically updated in response to user inputs, for example.
