During the course of this book, you have learned about the key tools to author, manage, and administer ArcGIS geodatabases. You have learned how to create a geodatabase, add datasets, create relationships, and much more. In the previous chapter, you learned some techniques that can be applied to the geodatabase to optimize and keep your geodatabase healthy. You might have noticed that running all these tools manually, especially in bulk mode, can be a hectic process. That is why Esri, the company that created ArcGIS, has made all these geodatabase functionalities available as geoprocessing tools. These tools can be combined and joined together to form other tools with different functionalities. They can also be called from various programming platforms such as Python to solve interesting problems, as we will see later in this chapter.
