Hat jemand Bock auf sowas? Damit darf sich Freidenker an der ZHW herumschlagen. Viel Spass aber… lieber du als ich 😉
Freidenker
dr claude und i hend drum wieder emol über datebanke gredet gha und do han i ihm gseit, dass i es fach han wo unter anderem sziel isch SQL queries bestmöglichscht zoptimiere.
für die wos bitz gnauer wend wüsse: SQL queries wo x subqueries mit x tabelle und x joins händ möglichscht an dr jewilig SQL dialekt vo dr jewilige DB so azpasse, dass das ganze möglichscht schnell und ressourcearm ablauft.
für die wo e ganz churzi version wend: feintuning an datebanke.
…bevor mir so öbis in dr praxis au mache – aso au wirkli an de datebanke umehacke – bruchts natürli zersch mol paar theoretischi grundlage, wo halt e mathematische hintergrund wo halt logik, mengelehre und paar algorithme e wesentlichi rolle spiele. das isch alles zämmegfasst unterm thema: „relationale algebra“.
