 ====== TC - statement ======
+''**public class TCStatement**'' \\
+''**implements Serializable**''
+Table Completeness (TC) statement describes a table completeness statement as it is defined by Razniewski&Nutt(VLDB2011).
+{{ :magik-demo:developer:schema2.png?nolink&600 |}}
+Namely, Compl(R(x);G) is a table completeness statement for the relation R,  and under the condition G.
+Condition G is a conjunction of atoms and x is a vector of arity R.
+A TC statement is satisfied with a partial db D=(Di,Da) if R(x)(Di) {{:magik-demo:developer:class:core:subset_of_or_equal_to_icon_256x256.png?nolink&11|}} (R(x),G)(Da).
