If SQLite is 'gaining some ground' it is a condemnation of reading
skills in general, and reference to Codd & Date in particular.
and "those who do not learn from history..."
Look at their website: SQLite.org
A) Their web page link for 'unsupported..' shows it missing critical SQL
tools that existed in RBase for DOS when I still had hair and 50 MHz was
a fast CPU.
B) Their FAQ, #2 and #3 explain that it ignores attribute typing, and
that you can put any type of data into any column except an
autoincrementing integer field. i.e - what you might have wanted to be
a date or integer or boolean is just as happy storing a string ......
or the reverse... or *whatever*!
They call this a 'feature', not a bug.
- Vending machines built with 'features' like that are all over Las
Vegas, Punta del Este, Monaco, and Macau...and are required to have
gambling licenses.
It gets worse. Have a look.
It may use, even abuse SQL, but it is NOT a Relational Database
Management System.
Object DB? - sort of,
'scratchpad', certainly.
But RDBMS? NFW!
Suggest a rename to: "SQLied", 'coz you can't guarantee any sort of
integrity if you don't care even about what *type* of data goes into a
field.
