AT&T's Daytona database is a DBMS capable of managing the large amounts of data involved in telecommunications systems, such as origin and destination of each call, time and length. According to AT&T, a single Daytona DBMS server can handle roughly 410 billion records in 40TB of disk space continuously.

Privacy controversy
In 2006, the Electronic Frontier Foundation lodged a class action lawsuit, Hepting v. AT&T, which alleged that AT&T had allowed agents of the National Security Agency (NSA) to monitor phone and Internet communications of AT&T customers without warrants. If true, this would violate the Foreign Intelligence Surveillance Act of 1978 and the First and Fourth Amendments of the U.S. Constitution. AT&T has yet to confirm or deny that monitoring by the NSA is occurring. In April 2006 a retired former AT&T technician, Mark Klein, lodged an affidavit supporting this allegation. The Department of Justice has stated they will intervene in this lawsuit by means of State Secrets Privilege.

In May 2006, USA Today reported that all international and domestic calling records had been handed over to the National Security Agency by AT&T, Verizon, SBC, and BellSouth for the purpose of creating a massive calling database. The portions of the new AT&T that had been part of SBC Communications before November 18, 2005 were not mentioned.

On June 21, 2006, the San Francisco Chronicle reported that AT&T had rewritten rules on their privacy policy. The policy, to take effect June 23, 2006, says that "AT&T — not customers — owns customers' confidential info and can use it 'to protect its legitimate business interests, safeguard others, or respond to legal process.'
