Originally the answer would have been that dbFront can integrate with a variate of reporting tools. Since then we have decided to add reporting directly to dbFront.
This was partially to make it easier for our users. Although there are a pile of reporting tools, many require serious effort to install or use.
You can still link to nearly any other reporting tool from dbFront but if you just need a quick simple report then the functionality that dbFront offer might just be enough.
