Ten years prior the events of Digimon Savers, mysterious events were occurring. For no apparent reason, people began disappearing one after another. Yushima and Satsuma, detectives at the time, were investigating these sudden cases. In response to those events at the time, a special team was organized, that was the Digital World Exploration Party, the predecessors of DATS. After returning to Real World failing to find Ikuto, Professor Daimon, still in the Digital World, sent blueprints for the Digivice iC and plans to establish an organization which would eventually become DATS.
After the DATS Team returned to the Real World upon the fall of Mercurymon, Kurata tricked Chief Hashiba into thinking that the members of DATS were traitors. In response to this, Hashiba orders them to have their memories erased as well as being put in confinement. After Masaru and the others managed to regain their memories, through the help of their partners, Kurata destroys the HQ building, before quickly escaping to the Digital World.
The Headquarters was eventually rebuilt as well as many areas globally, following the widespread destruction caused by the Royal Knights, Yggdrasill's rampage and the close collision between the Human and Digital Worlds. However, after the remaining Digimon in the Human World were sent back to the Digital World through the Digital Dive machine, the organization was disbanded.
