WHY USE IMPACT ANALYSIS DIAGRAMS ?
Impact analysis diagrams show the references to an item (table, column, object, method, variable, etc.) for SQL Server database T-SQL code.
Unlike Call Graphs that are multi-levels, Impact Analysis diagrams are single-level. But they show more details about the structure of the T-SQL code and the container(s) of the objects referencing the initial item.
