Implementing Basic Filtering in Your App


There are numerous ways to implement searching and filtering within mobile apps.  MobileTogether Designer allows developers to perform filtering on either your mobile app or on the server via a SQL query.  Knowledge of each of these methods, along with the use cases for them, is an essential tool every mobile developer should possess.

This video tutorial continues to build out the books database project that has been constructed in previous tutorials.  It will cover the steps needed to implement basic filtering in your mobile app.  Additionally, it also introduces developers to the usage of user defined XQuery functions which provide a method to centralize application logic.

Using Google Cloud SQL


Google recently announced their next generation of managed MySQL offerings on Cloud SQL, so we wanted to take it for a spin and create a cloud-based SQL database that we could then utilize as the back-end for mobile apps, or even for advanced data analytics from our desktop.

According to Google, the two principal goals of the second generation of Cloud SQL were better performance and scalability per dollar. It seems that they succeeded in these goals: the second generation Cloud SQL is more than seven times faster than the first. And it scales to 10TB of data, 15,000 IOPS, and 104GB of RAM per instance — well beyond the first generation. So it looks like the ideal, scalable cloud-based database back-end for mobile apps.
