Create Call Graphs with Visual Expert for SQL Server

WHY USE CALL GRAPHS?

A call graph is a diagram representing objects referencing each others (multiple levels).

This graph can be used to: 

  • Document the inner workings of an application, analyze every possible run.
  • Predict the impact of a change 
  • Track the flow of values between procedures
  • Detect anomalies of program execution, find procedures never called. 
  • etc.
