Hi there! Who could help to find the documentation about DB? If it exists.
- Is there the possibility to connect from a third-party app.
- Structure description.

No, external systems shouldn't connect directly to database. Here are a few reasons why not. Use integration options, such as web services, as we discussed recently in your two other threads.
What exactly do you mean by "structure description"? What business problem are you trying to address?
I guess this is about AX 2012 too, isn't it? Please select "Dynamics AX 2012" as the version in these cases. The option Microsoft Dynamics AX (current version) shouldn't be there at all, it's a relict from times when D365FO was called merely Microsoft Dynamics AX (without any version number). Unfortunately the admins neither renamed it nor removed it when they added separate forums for D365FO. I requested that many times, but unfortunately this invalid version is still in the lookup.
By the way, I see you've attached "Connector for CRM" tag, but you didn't mention it in your question. Can you please clarify whether your question is related to the connector and how, or whether you attached this tag by mistake?
