Mmm. These are really different subjects: SQLite has no redundancy support. You can manage backups of SQLite data, even if the database is currently in use. But the system does not have a fast way to know which pieces of data just changed. You can write that into your program, or just copy the entire database. You can write a program to take automatic backups, depending on how you define 'automatic'. > Another doubt is like : > When you say sorting contents in the DB, is this the same as Querying? The actual database file is not changed (resorted) each time you make a query. It is just that the reply to the query returns data carefully sorted into the order the query asked for. This is true for SQLite and all similar SQL systems.
