This chapter introduced us to the concepts behind multi value fields in Siebel CRM. Multi value fields allow us to create links between parent and child business components and provide a high level of usability to the end user by means of MVG and association list applets.
The chapter also provided a full case study example that demonstrated how to create a new M:M relationship between two business components and how to create the necessary repository object definitions in the data layer, business layer, and user interface.
In the next chapter, we will learn how to configure data security with Siebel access control.
