The Data Warehouse System — Electronic Surveillance Data Management System (DWS-EDMS) is an electronic database created by the Special Technologies and Applications Section (STAS) of the Federal Bureau of Investigation. Disclosed in a heavily redacted review of the FBI's role in the prevention of the 2009 Fort Hood shooting, its full capabilities are classified but at a minimum, provides a searchable archive of intercepted electronic communications, including email sent over the Internet.〔(【引用サイトリンク】title=Final Report of the Judge William H. Webster Commission on The Federal Bureau of Investigation, Counterterrorism Intelligence, and the Events at Fort Hood, Texas, on November 5, 2009 (unclassified version) )〕 Another report suggests that online chat transcripts, email attachments, and audio of unspecified origin are stored.〔(【引用サイトリンク】title=Congressional Budget Justification, FY 2009 )〕 By the third quarter of 2006 it was involved in 130 successful investigations and 370 active cases.〔(【引用サイトリンク】title=FY 2008 Congressional Budget Submission )〕 In June 2007 a total of 70 million intercepts from 16,500 online accounts were present on the system, and were expected to increase to 350 million intercepts from over 50,000 accounts by June 2009.〔 == History == The DWS was designed by STAS in 2001 to record a certain class of data intercepts. In the following years it became a de facto depository of a wider category of intercepts, surpassing its original intent and straining its hardware limits. The DWS was involved in the interception of 18 email messages between Nidal Malik Hasan and Anwar al-Awlaki from December 2008 to June 2009, although the messages were largely benign and provided no actionable evidence. It was upgraded in February 2009, improving the user interface and tools, and merged with a related system, EDMS. The user interface was again improved in May 2009. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Data Warehouse System Electronic Surveillance Data Management System」の詳細全文を読む スポンサード リンク
