I am looking for a reporting tool that can be layered over an existing MySQL database and used via the web my many users to chart/graph/dashboard data specific to each user. What is a good solution for getting this done? LogiXML, SAP, etc?
Determining your requirements first will help filter your many choices.
What is the definition of "dashboard"? Does the data remain in MySQL? What is your budget? We offer RapidStack as our solution for your scenario where the data stays put in your network but you have web based access to query, report, and dashboard. There are many solutions, including free and low-cost services from google, SAP and others, if you are fine with moving the data up the the cloud, aka other peoples servers, or into excel first.
