Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student
Project Nightingale is a data storage and processing project by Google Cloud and Ascension, a Catholic health care system comprising a chain of 2,600 hospitals, doctors' offices and other related facilities, in 21 states, with tens of millions of patient records available for processing health care data. Ascension is one of the largest health-care systems in the United States with comprehensive and specific health care information of millions who are part of its system. The project is Google's attempt to gain a foothold into the healthcare industry on a large scale. Amazon, Microsoft and Apple Inc. are also actively advancing into health care, but none of their business arrangements are equal in scope to Project Nightingale.
