xBlog doesn't have its own database. It prompts the content of fields of foreign tables and extensions to the frontend.
These fields must registered. A lot of default fields are registered by default.
There is something like a bridge, to connect fields of foreign databases with the frontend.
You are controlling registered fields by the Constant Editor. Please refer to
Look for the sections 'fields'.
If there is a need for a new field with a new workflow, you should register it. Please refer to
