Impact Analysis

Assess the consequences of a change

Identify which items need to be updated to accomplish a modification.
Don't break your application after a change!

When you need to modify your application, it is important to know the potential consequences of the change in the source code to avoid regressions.

The static code analysis performed by Visual Expert allows you to find all references to a given item: variables, functions, objects, columns, tables, procedures, etc.

Visual Expert answers typical questions like:

  • This variable has changed: what are the consequences on my code?
  • If I add a parameter to a function, which calls should I update?
  • If a table or column is changed, where is it used in my code?
