php - Should I use Firebase for my Android APP if I know server coding? -

should use firebase ? have read firebase , new me. know sql , php server side coding.i want create android app provide users interact each other , contain follow each other, send image , chatting each other should use hostgator (my hosting) or better use firebase in case ? paying $13 per month hosting

answer should contain followings:

1)firebase or hostgator better in case?

2)why?(explain details if possible)

3)which 1 cost less

4)will able change 1 (from hostgator firebase , reverse) ?

1) firebase , regular sql (like hostgator) aren't same. firebase provides realtime database. means if change value of entry, change on every devices connected. also, suppose hostgator using rdbms (relation database management system), in case, need create structure stock data (datatables, columns ...) don't need in firebase (and other nosql dbms).

2) there not obvious better option. depends on want. shoud @ firebase documentation : https://firebase.google.com/docs/database/. personnaly used firebase 1 android project in order push notification, , have admit easy implement.

3) firebase provides free-tier , $25 1 several options : https://firebase.google.com/pricing/. rdbms (mysql, postgresql, oracle ...), depends of server, can have 1 free or $10.000 one. both job.

4) lot of work, yes can. said in 1), firebase doesn't need fixed architecture, while rdbms needs one. import firebase rdbms, you'll need fix 'problem', , before importing, create tables, columns, foreign keys etc... rdbms firebase, hard thing keys generated firebase. never did that, can't tell, seems quite easy : migrating data firebase mysql biggest problem changing entire application if want change 1 another.
