Facebook has a SQL like query language, FQL, which allows you to request
various data points about your pages, applications, etc. When you need a
single data point like your page's total fans, you make a call to the
method, fql.query
to get your data. For a single data point this is great, but what if
you are building a chart and need more than one data point? Making
repeated calls to Facebook, will quickly begin to become tedious and
slow. Luckily, Facebook has another method, fql.multi-query, which allows you to submit multiple queries at the same time and receive them back in a single result-set.
