Abstract
In today’s world, many decisions are made on data received. Approximate Query Answering provides fast, highly, accurate approximate answers to queries. Aqua provides approximate answers using small, pre computed synopses, samples, counts, etc of the underlying base data. According to [2] Approximate QUery Answering ,AQUA System, is the first system designed to provide fast, highly accurate approximate answers to a broad class of aggregate and set valued queries.
