Types of table

For this discussion, we will dpide table types into three categories. As developers, we can change the definition and the contents of the first category (the Fully Modifiable tables). We cannot change the definition of the base fields of the second category, but we can change the contents (the Content Modifiable tables) and add new fields. The third category can be accessed for information, but neither the definition nor the data within is modifiable (the Read-Only tables).
