In this chapter, we focused on the basic building blocks of Business Central data structure: fields and their attributes. We reviewed the types of data fields, properties, and trigger elements for each type of field. We walked through a number of examples to illustrate most of these elements, though we have postponed exploring triggers until later, when we have more knowledge of AL. We covered data type and FieldClass properties, which determine what kind of data can be stored in a field.

We discussed filtering, how filtering is considered as we design our database structure, and how users will access data. Finally, more of our Business Central Radio Show application was constructed.
In the next chapter, we will look at the many different types of pages in more detail. We'll put some of that knowledge to use to further expand our example Business Central application...
