In this chapter, we focused on the foundation level of NAV data structure: tables and their internal structure. We worked our way through the hands-on creation of a number of tables and their data definitions in support of our WDTU application. We briefly discussed Field Groups and how they are used.
We identified the essential table structure elements including Properties, Object Numbers, Triggers, Keys, and SumIndexFields. Finally, we reviewed the several categories of tables found in NAV 2017.
In the next chapter, we will dig deeper into the NAV data structure to understand how fields and their attributes are assembled to make up the tables. We will also focus on what can be done with Triggers. Then we will explore how other object types use tables, working towards developing a fully featured NAV development toolkit.
