[BD] Modelo Relacional


Recommended Posts

Tenho-me apercebido de que há por aqui muita gente que não sabe o mínimo de bases de dados.

Para colmatar essa lacuna, deixo aqui um tutorial que deve ser lido e compreendido antes de se pensar sequer em desenhar qualquer esquema lógico (e muito menos implementar o físico):

10 REM Generation 48K!
20 INPUT "URL:", A$
30 IF A$(1 TO 4) = "HTTP" THEN PRINT "400 Bad Request": GOTO 50
40 PRINT "404 Not Found"
50 PRINT "./M6 @ Portugal a Programar."
