I am developing an application for Windows phone 7 which uses offline database. I have seen some of the solutions for this as follows Sqlite DB http://sqlitewindowsphone.codeplex.com/ Mango DB http://www.kunal-chowdhury.com/2011/06/windows-phone-7-mango-tutorial-24-local.html
My Question is All these databases are using Native code i.e development in C#. But i would like to develop local database either phonegap or javascript or else any other which uses for cross platform applications (windows phone in particular). Thanks in Advance.
