Planning is of the essence, thinking ahead to what you want to accomplish with the GIS services can put you on the right track and save you time and resources. In this chapter, you learned how to analyze requirements and plan your GIS services. You then designed the nominated GIS services with UML tools. You also used an ER diagram to design the geodatabase that feeds the services. You eventually implemented your GIS services using the techniques you learned in the previous chapters. The skills you have acquired in this chapter will help you effectively plan a new ArcGIS for Server implementation. In the next chapter, you will learn new approaches for optimizing your ArcGIS to help the server run more efficiently.
