This paper proposes a natural language (NL) query-based response system in the Healthcare domain. Today, autism spectrum disorder (ASD) is a big issue among children and most parents are unaware of this disorder. Awareness about this disorder is very important and very much needed for parents to identify ASD in their children at an early stage to start treatment. Our proposed system will extract information about ASD from a database using NL queries. Sometimes the NL query may ask for some aggregate data from the database which may be difficult to process this proposed system is able to handle conventional queries with aggregation and generates responses from the healthcare database. A combinational algorithm has been approached where SQL has been generated from the NL query.
