We talked about environment variables, what they are, how they are used in PRD, and what information each of them provides us.

We also talked about stylesheets, what they are, what they let us do, and what CSS rules are. Then we saw how PRD implements stylesheets, how they are saved, configured, and applied to our reports.

We created a simple report and applied a stylesheet to it that we created step-by-step. The CSS rules were based on the user executing the report.

Later we talked about crosstabs, what they are, what their purpose is, and how they are used and configured in PRD.

We created another report, added a crosstab to it, and configured the crosstab.

Finally, to put into practice what we saw in this chapter, we proposed that you modify an existing report and modify the visibility of a chart according to the user currently logged in.

In the next chapter we will see how to embed and run PRD reports in our web applications.
