HEllo, are you there?
I am not sure exactly what you are looking for, but depending on the business structure, most of this information is available through your state's secretary of state office. In addition, you can try a public records search down at the county clerk/recorders office. Some clerk/recorders offices have this online, other you have to appear at the counter to search business records, but in the end all of this is public information.
I hope this is acceptable.
THe point of my answer is that there is not a magic source of who owns what. The secretary of state and your county recorder maintain business records which contain the minimally required information about who owns a business. For a corporation that is the primary address and agent for service of process. For sole proprietorships the local government will maintain business license records. In addition, DBA individuals must (in most jurisdictions) must advertise the license.
Additional sources are county deed records which will tell you who owns particular businesses.
What the SOS office is not going to give you is an exhaustive list of everyone involved with the (a) business. Often this sort of information takes considerable time to uncover depending on the type of business and how deep you want to go.
