Chessbase is perhaps the most used software in terms of database and learning @K_Iniyan .It is paid though, but really an useful tool.
If you want something for free then you can use the chesscom or even Lichess databases.
I'm pretty sure this is the link https://chessbase.in/online-shop/

Btw, Not sure 'bout the link

"Scid vs. PC" is a great free database, kind of a strange name but it is really good for a free database.

http://scidvspc.sourceforge.net/

chessgames.com and chess365.com are good and free
the masters database at lichess is decent and free as well
Unless you are a GM or play ICCF, you probably do not need to spend money on chessbase.com.

ChessX is probably the best free chess database program today. If you are using Ubuntu, ChessX is in Ubuntu repositories, and there is no problem with installation.

Somebody have a link to a 2 million+ classical PGN database? Use to could search up a few good ones pretty easily but can't find many now.
