MySQL Database Design Question-spun3

MySQL Database Design Question,[url=http://rogervivieronlinesale.olimx.com/][b]roger vivier sale[/b][/url]
I won't post it here unless you really have trouble, but they are very simple queries,[url=http://duveticaitaliaoutlet.webmium.com/][b]duvetica online store[/b][/url], so I'll leave that for you to exercise.
With many to a lot of relationships,[url=http://peutereyoutletitaliaonline.olimx.com/][b]Peuterey Uomo Jacket[/b][/url], if you normalize then you end up getting more tables and would require more joins. If you have to retrieve this info very regularly joins could be very costly and add a large amount of overhead.
If you decide to put things into one big table then you're increasing data redundancy,[url=http://woolrichparkaschweiz.albirank.net/][b]Woolrich Parka Schweiz Online Shop[/b][/url], which wastes space for storage,[url=http://giuseppezanottisneakerssale.olimx.com/][b]discount giuseppe zanotti sneakers[/b][/url], but is worth it in the event that mixture of columns will always be queried because of better index usage with no joins. It however increases application development complexity. This is particularly the situation when you have exactly the same columns in different tables because of denormalization and end up needing to remember updating both tables,[url=http://giuseppezanottichainsandals.olimx.com/][b]discount giuseppe zanotti chain sandals with big promoton[/b][/url], which increases the chance of data inconsistencies if you forgot to update either one.
So it really depends upon your circumstances,[url=http://billigmonclerjackenkaufen.olimx.com/][b]Moncler Jacke Damen Outlet Deutschland[/b][/url], if preformance is key and also you don't mind the elevated complexity and possible data integrity issues, then take on a denormalized approach.
If however performance isn't a big issue (not a lot of rows, very little users, more than enough hardware,[url=http://duveticadoudoune.halod.com/][b]Femmes Manteaux Duvetica[/b][/url], speed isn't concern) then separating the relationship tables would decrease space for storage (pointless nowadays since its so cheap),[url=http://peutereyoutletitaliaonline.olimx.com/][b]Peuterey Outlet Italia Online[/b][/url], increase data integrity,[url=http://discountnikesoccershoes.webmium.com/][b]http://discountnikesoccershoes.webmium.com/[/b][/url], decrease data inconsistencies and reduce development complexity
