Whether you use a template or create your app from scratch in App Engine Studio (AES), you must enhance it by
creating a data model, user experiences, logic and automation, and security.

If you're creating apps in AES, you may be able to open your app in ServiceNow Studio depending on your permissions. If the ServiceNow Studio banner is displayed when you open your app in AES, select Try it out.

Use the following topics as guides as you build out your application.
* **[Resources for enhancing your app](https://servicenow-prod.fluidtopics.net/RgwjJt25iB_fFFt28fYSKA)**   
  As you add data, experience, logic and automation, and security to your application, you might interact with several different parts of the ServiceNow AI Platform. The links in the following table point you to resources for adding content in App Engine Studio and also Table Builder, UI Builder, Decision Builder, App Engine Management Center, and the ServiceNow AI Platform.
* **[Create a data model for your application](https://servicenow-prod.fluidtopics.net/sBUU39XKAFpc6eT3sEejzQ)**   
  Create a data model in App Engine Studio (AES) for your application by creating the tables that will house your application data. Create data tables that will be used in your application by creating the table from scratch, uploading a spreadsheet or PDF, or by using an existing table as a template. You can also create and schedule data imports by mapping a spreadsheet to an existing table in your application.
* **[Add an application experience](https://servicenow-prod.fluidtopics.net/YFyPnkNWeyV~9QVe5IxHSQ)**   
  Use App Engine Studio (AES) to add an experience to your app. Experiences are the interface, or wrapper, for how users interact with your app.
* **[Add logic and automation](https://servicenow-prod.fluidtopics.net/rM8ysRie1MDs7erpPUQeWA)**   
  Replace manual work by adding logic and automation to your app in App Engine Studio (AES).
* **[Add application security](https://servicenow-prod.fluidtopics.net/lGBiWQYGFF~Ys_U2gG0NFw)**   
  Control who is permitted to use or edit your application by configuring roles in App Engine Studio (AES).
