Er... Comparing []XT to an SQL database is a bit like comparing apples
and orangutangs. []XT is much easier to use than a relational database
if your queries are easily expressed using APL primitives (like
DATA[5;] :-). Internally, []XT is pretty much a component file, except
that it appears in the workspace as an array.
Relational databases have all sorts of additional features which may
or may not be useful, this really depends on the application, whether
you need to share data with non-APL applications, etc.
Personally, I would probably use a "regular" component file, these are
more portable - have better inter-operability across platforms, better
multi-user controls, etc - or a memory-mapped file, as Veli-Matti
suggests. I think of []XT as a tool for very simple data storage
requirements.
