Sqlite Multiple Table

  1. 1. Think Android Lesson : Sqlite Multiple Tables By : Danang Kukuh P
  2. 2. What is Sqlite?  SQLite is an Open Source database. SQLite supports standard relational database features like SQL syntax, transactions and prepared statements.
  3. 3. Sqlite in Android  SQLite is embedded into every Android device. Using an SQLite database in Android does not require a setup procedure or administration of the database.  You only have to define the SQL statements for creating and updating the database. Afterwards the database is automatically managed for you by the Android platform.
  4. 4. Sqlite Multiple Tables  I explained how to use SQLite database in your android application. But that covered the scenario, only when you have one table in the database. I am getting lot of queries about handling the sqlite database when it is having multiple tables.
