The present disclosure describes methods, systems, and computer program products for dynamic generation and modification of input schemas. One computer-implemented method includes receiving event data from a data source with an event collector, the data source registered with the event collector to transmit event data to the event collector, transmitting the received event data for analysis, saving the transmitted event data, determining whether to create or update a business intelligence view, determining whether to create or update an input schema based on the saved event data, and providing, by a computer, an input schema describing how data is represented in the database to a query generation engine.
