I want to connect/use (interface) the data with WordPress BuddyPress plugin

Question

Hello team, 
 

I've checked the Family Echo system and it really impressed me to manage the family group and family trees. 

I want to connect this family data to WordPress BuddyPress (https://buddypress.org/) plugin. 

 

How can we deal with submitted data? 

How can I get the data from Family Echo? 

What should be the Database structure?

 

Thanks!
