At my work I had a long SQL stored procedure code (coded by someone else) which was difficult to understand at first. I was Looking for some tool which could do the job of creating flow diagram of the code. But didn’t find any.
Few days later a friend sent me an email with a link to a tool which can create flow diagrams of almost any code (T-SQL, Java, VB, .NET etc). I’ve tried its demo version which created a flow diagram of my code in 5 sec. Wow.. That was gr8 if I compare it with the 2 days efforts I took to manually create the flow diagram in Visio. Though after comparison I like my Visio :). But still it’s a handy tool for a quick look at the code.
Check it out these tools.
Visustin v3 Flow chart generator (I’ve tried this one)
SQL Diagrams 2004
Data Flow Diagram (with Case Studio 2)
Later on while searching I found another interesting tool. I haven’t tried it yet, but it looks like you can code (or edit code) just by making diagrams.
