I have about 10 types of CSV files. Each of them has got different header (row) data structure. Is it any way to store them in PostgreSQL and then read in frontend? I've done some reasearch and found opencsv but I guess that it's not full solution of problem.

What you have to do is to map yourcsvfiles to yourtablein the database. OpenCSV should help. Everything you mentioned above is possible. I guess you don't know how to design your program ?
