Assigned the JACKSON ONE SID. Prior to the departure we entered the JACKSON ONE SID and verified it. On climbout the FMS switched to the next point prematurely instead of going to OED [VOR] as depicted on the chart and the aircraft gave cues to turn to the left. I followed the cues and began turning to the left. We were about to switch to green needles and fly directly to OED when ATC told us to look out for traffic ahead so we continued straight ahead until cleared to turn. That's when ATC told us [of a] possible pilot deviation and that this occurrence happens often.  [Caused by] faulty database. According to ATC it's an ongoing problem with the JACKSON ONE departure. Verify the departure on the ground and be aware that the FMS may give you wrong cues but don't follow them. Go to green needles.
Prior to departure; we entered the SID and verified it in the box. After takeoff; the aircraft was following the SID; then a few miles before the VOR; the aircraft started turning left as if it was entering the procedure turn prematurely. We were just about to switch to green needles and continue to the VOR when ATC queried us and said to maintain heading and look for traffic. We saw the traffic and maintained visual separation. We then continued on course per ATC. ATC also said that this happens often. Bad database. According to ATC; it is an ongoing problem with the JACKSON ONE Departure. Verify the departure before takeoff; and switch to green needles if the FMS starts acting up.
Air carrier flight crew reported flying the JACKSON ONE SID as published and told by ATC they were off course.
