Xindi database The Xindi database stolen by , at the outset of the starship ' s voyage in the Delphic Expanse , was one of several key intelligence prizes snatched by Starfleet during the search for the Xindi weapon . It contained comprehensive data about the Xindi , who were largely ciphers to both Starfleet and the Vulcan High Command at the time . Knowledge gained from the database heavily influenced Jonathan Archer ' s response to the Xindi threat . Circumstances of retrieval . The database was obtained by an Osaarian merchant ship from a Xindi spaceship which they attacked . After the encountered the pirates ' hideout in a mysterious and ancient sphere , Ensign Hoshi Sato surmised that such a database was also in the pirates ' possession , and would aid the " Enterprise " ' s search for the Xindi . With the access codes having been acquired from an Osaarian pirate that Captain Archer was holding in the brig , the database was forcibly downloaded via a comm link by Sato , as " Enterprise " flew less than a kilometer away from the pirate ship . ( ) Usage . Archer not only attempted to use this database in order to locate the Xindi weapon but also operated it to learn much about the Xindi themselves , including the different species of which that group was comprised . ( ) For instance , it was through this database that he first became aware of the Xindi - Arboreal s , knowledge that later allowed him to make a positive identification of such individuals when he actually encountered them for the first time . ( ) The database also provided Xindi shuttle design specifications and the location of Rajiin ' s homeworld . ( ) However , other information proved more elusive , as Archer once spent hours merely trying to understand the way in which the Xindi organized their star chart s . ( ) Analyzing sensor log s from the database enabled T ' Pol to postulate the existence of a second sphere , much like one they had encountered when they had first obtained the database . ( ) The database thus allowed " Enterprise " to begin to uncover the existence of the whole network of spheres that created the Expanse . ( ) Possible loss . After helping a religious order which had run into trouble , was commandeered by the group ' s leader , Pri ' Nam D ' Jamat , who determined that Archer had desecrated the spheres , which were central to D ' Jamat ' s religion . As punishment , the Pri ' Nam deleted a significant portion of the " Enterprise " database , though it wasn ' t clear exactly how much of the Xindi database was affected by this purge . ( ) Nevertheless , Sato and T ' Pol reconstructed about thirty percent of the lost data by the time " Enterprise " rendezvoused with Commander Shran . ( ) Diminished importance . After an Andorian attempt to capture the Xindi prototype weapon , Shran secretly transmitted detailed scan s of the weapon to " Enterprise " . ( ) This more specific information – along with the fact that Archer tricked Degra into revealing the location of the weapon – presumably superseded the information in the database . ( , et al . ) As Archer formed alliances with the majority of Xindi species , the need for the database diminished further . ( )
