In this lesson, you learned that data objects are representations of data based on a flat file or a relational database source. You learned that you can create a flat file data object and preview the data in it.
You uploaded a flat file and created a flat file data object, previewed the data for the data object, and viewed the properties for the data object.
After you create a data object, you create a default profile for the data object in Lesson 3, and you create a custom profile for the data object in Lesson 4.
