Approaches to building an efficient database -

-

i wondering if draw on experienced database designers. i;m not experienced building databases , have project complete within set time (couple of months). requirement build third normal form.

i wondering best way start be? should go ahead , build works (trying efficient possible) go , refactor parts can improved or there methodology follow ensure degrees of normalisation start?

do not build database intent go later , normalize it. databases not refactor application code 1 thing , another, have requirement follow third normal form, so start, far less work , in end far better product. there not shortcut correct database design in third normal form. understand before starting deisgn.

if unfamiliar database dsign in third normal form, go spend couple of days doing reading on database design. spend day or reading performance tuning database - designing database start perform save lot of time. doesn't take longer designing poorly performing datbase, once know , avoid. first advice couple of big fat books , read in depth before start. time spend doing repaid in ability things better through rest of project.
