Note: I am working on entirely new papers (not re-writes) in the PRACTICAL DATABASE FOUNDATIONS series. Two were already published:

THE FIRST NORMAL FORM - A DEFINITIVE GUIDE
PRIMARY KEYS - A NEW UNDERSTANDING

and are available for ordering from the PAPERS page.

One is in progress:

RELATIONAL DATABASE DOMAINS: A DEFINITIVE GUIDE

and two are forthcoming:

DATABASE RELATIONS: A DEFINITIVE GUIDE
THE FINAL NULL IN THE COFFIN - A RELATIONAL SOLUTION TO MISSING DATA

will be forthcoming.

In the process I come across matters that, while not includable the papers, are worthy of setting straight in brief posts here. Here is another:

“Data is stored in two-dimensional tables consisting of columns (fields) and rows (records). Multi-dimensional data is represented by a system of relationships among two-dimensional tables.” 

• FT Data Sublanguage & Programming Languages
• FT Relational Domains & Programming Data Yypes
• TLC RDM & "Arbitrary Data Types"
• FT RDM & Complex Domains
• FT RDM & Objects Permanent Identification
• SMS Surrogate Keys
• FT Primitive & Derived Domains
