I will read more on SQLite/WebSQL/IndexedDB. Let me ask more clear question. where exactly above database/storage techniques (websql/IndexedDB etc) store their data ? * Local File * Local browser cache or cookie or similar things * WebServer OR Is it possible to just READ and Display a database content from file ( Ex xyz.db) in index.html without having any server. (Ex - File mode).

At the same Time, I cannot create these Quiz application for test or experimental API or feature, because a huge amount of Quiz to be generate which will be include for education of student at national level. So one should be able to open the Quiz files after 5-6 years too. -- ┌─┐ │Narendra Sisodiya │http://narendrasisodiya.com └─┘

Some (not all) browsers do allow you to see the contents of the db locally, at least when it comes to websql. I'm not so sure about indexeddb right now. May I have list ? At least one browser support will do. Student can open XML files and check answers. This is why I am looking for local database as this will create the task relatively difficult. Also files are mostly self-assignment , just like normal book which always has answer at the end of book. so having access to answers will not make much issue.
