In order to prepare a SQLite database for your Android application, you only need to follow a few simple steps. Learn what those steps are and the importance of having an abstraction layer for your chosen database solution.
- [Instructor] In order to prepare a SQLite database…for your Android application,…you only need to follow a few extra steps.…The first step in the process…is to create the contract for our tables.…A contract is just a container class…that holds onto the Constance that we need…in order to define the table names and columns.…It helps with the maintainability of your application…as changes to naming will not impact multiple classes.…Next, we'll need an SQLite open helper class.…
This class saves us from the heavy work…of managing database creation…and version management on our own.…Now only does it know when we need to have…our database created,…it also knows how to provide us with connections…to our database when we request them.…The final piece of the puzzle is a wrapper class,…or you could say some type of abstraction layer.…Now this is optional, however, I highly recommend…having one as it keeps your code organized.…
In this course, I will use a data source class…to serve as my abstraction layer.…You will see how I'm able to rotate…
To begin, Annyce Davis reviews using the de facto data persistence solution available on Android: SQLite. She takes you through basic SQLite concepts—such as how to create a database wrapper and insert data into a table—as well as a few more advanced topics. Next, she covers working with Cupboard, an open-source project dedicated to simplifying your SQLite interactions. To wrap up, she dives into working with Realm, an object database solution designed with mobile devices in mind. Throughout the course, Annyce discusses establishing relationships between database tables, creating and running queries, as well as performing data migrations.
