In a recent article, you assert:

"... (Oracle is, of course, a SQL DBMS, not a true RDBMS)"

Can you direct me to a source where I can learn the distinction between these two database management systems? I haven't been exposed to the term "SQL DBMS" before and am having a more difficult time digesting the concept.

Oracle is a SQL DBMS, or in other words, it is a DBMS based on the SQL data language; a true RDBMS is a DBMS truly, fully and correctly based on the relational data model; in the industry there is a common mistake that SQL-based DBMS are RDBMSs: SQL is not a true, full and correct implementation of the relational model; Most of the information on these distinctions can be found in the books listed on the Books page of this web site.

Thank you... I was at the DBDEBUNK site as your response arrived. There's a prodigious amount of material to learn.

Well, I don't think anybody can be a decent database practitioner without some fundamental knowledge. With the proper amount of knowledge you wouldn't have had to ask the question you asked. Lack of such knowledge requires an education and the web site provides some of that education. There are no shortcuts.
