+==============================
+
+Constraints:
+
+- The problem is modeled like a spreadsheet, with columns of data and formulas
+
+- Some data depends on other data according to formulas. When data
+  changes, the dependent data also changes automatically.
+

+Possible names:

+- Spreadsheet
+- Dataflow
