In this chapter, we briefly introduced Tasker, our example application. We went through the system architecture and the database server we are using. We described the data models in more detail, namely PERSON, TASK, and TASK_COMMENTS, as well as how the data relates to other data. We mentioned the business logic; this is in the code package for the book, but it's all self-explanatory, so we didn't include any code in the text. Finally, we covered the permissions model for the app.

Chances are good that you might not have to worry about how to create data models, writing business logic, or designing a complete system architecture since a lot of this might be done for you (more likely in a larger enterprise). If you do have to design your own models and logic, you might want to refer to the Designing the data models section in Appendix, Useful Resources.

In the next chapter we'll cover some important security aspects when it comes to building Cordova apps and web services.
