# Java程序设计 vs MySQL数据库宝典

The clearest difference is ads: MySQL数据库宝典 at none against Java程序设计's shown. MySQL数据库宝典 also leads on iOS requirement (9.0 vs 12.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Java程序设计 sells 1 one-off in-app purchase and MySQL数据库宝典 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
