An object can have a list attribute that represents a one-to-many relationship. These are defined in majic files with the QREL or BREL keywords. A list exists at the object level—it does not take any additional storage in the DBMS.
The CA SDM system handles list collections as abstract data types. The Web Services provides several methods to interact with lists—for references and queries to lists defined in an object, use getRelatedList() and getRelatedListValues(). For more information about lists, see CA SDM Lists in this chapter.
