Dbase development & tutorials

[Ochal Christophe]

Hi all,

Owning a PocketPC i planned on making a dbase on it to store a list of
dvd's & cd's i own, only to come to the conclusion that there are no
decent freeware database apps on that platform.

So, instead of whining about it, i decided to get of my lazy arse &
write one myself.

Unfortunatly, i'm unfamiliar with databases or how to create such an
app, does anyone know of some tutorials about this matter?

Cheers

On modern machines, you can often get away with using text files as
relation tables; for example having each table row as a text file line,
and table columns separated by tab characters. Depending on table size
and virtual memory, you may be able to keep tables in memory. You can
then use stdio functions and build up the functionality you need from
there.

Hmm, that does sound feasable, but considering the restrictive nature of
PDA's and other mobile devices, space is very much important, and even
using a textfile would pose problems concerning deleting & inserting
rows and or colums... I'd have to read in the whole thing and write it
in one pass each time.

Still, this would make for a small, simple engine wich is what i'm
looking for more or less.
