connect "default members data base" and new database

hi guys

first time poster. i have two questions. i have created a new database which captures members
-company
-role

so my question is with this data how do i connect the above two fields to the current existing fields being

-members user name
-members image

i was wondering i can collate all the above data onto a dynamic data page?

i want to know how i can get my members details into a dynamic page?
