问题
I wanted to know which database does the Samsung Galaxy Gear 2 support. Gear 2 being based on Tizen I tried using the Web SQL database. However on the emulator it shows that the Web SQL is not supported.
Can anyone tell me which database is supported for the Gear 2 ?

There are 3 ways get this done .. HTML5 Webstorage, IndexedDB and good old Files . More importantly, the Tizen wearable sdk comes with sample code
HTML5 WebStorage Example.
Since your apps are written in HTLM5 and compiles using a webbrowser-like runtime engine, you can use the HTML5 Web storage paradigm for data storage and retrieval.
localStorage.setItem("lastname", "Smith");
// Retrieve
document.getElementById("result").innerHTML = localStorage.getItem("lastname");

The best way to persist data would be on your phone. All communication 100% goes through Bluetooth to your phone via SAP. You can send data to your phone and have your integrated android app handle the db.
