Impact Analysis Diagrams
With Visual Expert for SQL Server

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.

Impact analysis diagrams are very useful to:

  • Evaluate the consequences of a change.
  • Identify the pieces of code that should be modified to accomplish a given change.
