How much now, as a percentage out of 100, are contributors to this newsgroup prepared to estimate the "realisation" of the relational model of data within the SQL-DBMS vendors (ie: IBM - DB2, Oracle, MS - SQL Server)

The rating of 100 equates to full realisation of the RM. The rating of 50 equates to half realisation of the RM. The rating of 10 equates to 10% realisation of the RM. The rating of 0 equates to zero realisation of the RM

My estimate/opinion is around 80% give or take 10%.

What is your estimate and/or opinion?
