Question

SQLite is a database that comes with Android. Which statements is/are correct?

The content of an SQLite database is stored in XML formatted files because XML is the only file format supported by Android OS.
A SQLite database is just another name for a Content Provider. There is no difference as the SQLite implementation implements the Content Provider interface.
If an app creates an SQLite database and stores data in it, then all of the data in that particular database will be stored in one, single file.
A database query to an SQLite database usually returns a set of answers
To access individual entries, SQLite provides a so-called Cursor to enumerate all entries in the set.
This is yet another example of the Iterator pattern.

Answer 1

1. Wrong as per my knowledge, SQLite may be an electronic database software that stores data in relations(tables).

2. Wrong. Content provider interface controls the flow of knowledge from your android application to an external data storage location. Data storage is often in any database or maybe it'll be possible to store the info in an SQLite database also.

3.Right. SQLite uses one file to store data. It also creates a rollback file to backup the stored data/logs the transactions.

4. Wrong. The queries are almost like a traditional electronic database system, the queries are going to be answered as per the conditions given and should return a group of answers or one answer depending upon the info and sort of query used.

5. Right. A cursor helps to point to one entry within the database table. this may be very helpful in manipulating the present row of the query easily.
