The queries comprise parameters indicating a date range and filter limitations defining the desired event data. The system selects storage blocks based on the date range and filters event data in the storage blocks based on the filter limitations. The filtered event data is grouped into a results message and sent to the client system via the network connection."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data query interface system in an event historian","description":"An event historian system receives and responds to queries for event data from a client device over a network connection.
