# SQL教程 vs Java编程手册

The clearest difference is rating: SQL教程 at 5.0 against Java编程手册's 2.3. Java编程手册's advantage is update cadence (every 3 weeks vs every 4 months) and ratings volume (3 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SQL教程 sells 1 one-off in-app purchase and Java编程手册 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

SQL教程 holds the better App Store score, 5.0 against 2.3. Both are backed by a comparable volume of ratings — 1 and 3 respectively.

SQL教程 ships an update every 4 months, Java编程手册 every 3 weeks. The most recent releases landed on September 11, 2026 and June 1, 2026 respectively.
