Weekly Update


1.  Quote of the Week
I do not understand your first point. Even a database designed with only 1NF can have integrity if other methods are used to ensure that integrity. [Higher n]ormal forms can guarantee the absence of various integrity issues, but the lack of a normal form does not guarantee the presence of the integrity issue. I remember writing pages of code to do just that in the early days of RDBMS products before normal forms (i.e., referential integrity) was strictly enforced by the DBMS. --LinkedIn.com
Note: My (first) point was that the minimal relational mandate is 1NF, but that full normalization (5NF) is desirable for practical reasons.
