 ===== constraints/editFDC.jsp =====
+For **REMOTE** schemas, one needs to edit schema database schema using favorite database management program. For example, to create a finite domain constrain using ''ENUM'' construct in PostgresSQL database one can execute the following code:
+<code sql>
+CREATE TYPE school.type as enum ('primary','middle');
+</code>
+In this way new data type is created. Then defining attribute name is some table to be of this type, create Finite Domain Constraint on that attribute.
