+# Beam SQL in Calcite: Overview
+
+[Apache Calcite](http://calcite.apache.org) is a widespread SQL dialect used in
+big data processing with some streaming enhancements. Calcite provides the
+basic dialect underlying Beam SQL.
+
+The following table summarizes Apache Calcite operators and functions
supported by Beam SQL.
+
+<table class="table-bordered table-striped">
