Chapter 2. Developing Custom Applications

The ServiceNow platform provides a rich functional interface for getting things done, whether you are building a new application or using it. Chapter 1, ServiceNow Foundations, looked at some basic elements, such as creating tables and fields to store your data, and how your data is displayed in tables and fields. This chapter builds on those fundamentals, looking at more ways to connect and model data, build applications faster, and prevent unintended consequences through conflicts. It's a little like having an architect providing that extra flourish to make our hotel not only sturdy, but also work well.

In this chapter, we will cover the following topics:

• How ServiceNow Studio provides a single, integrated IDE that collects everything in one place
• Seeing how applications control the flow of information with myriad of settings and options
• Use Delegated Development to let other users configure your application
• Using hierarchical tables to improve reuse through inheritance
• Connecting records using many-to-many relationships
• Handling the deletion and creation of records through reference fields
