Each row in the SYSDEPENDENCY system view describes a dependency between two database objects. The underlying system table for this view is ISYSDEPENDENCY.
A dependency exists between two database objects when one object references another object in its definition. For example, if the query specification for a view references a table, the view is said to be dependent on the table. The database server tracks dependencies of views on tables, views, materialized views, and columns.
