some pictures & been busy doing some development..

photos taken out of boredom


i've been busy doing some app and now have to find out the way to join 3 tables with a single Structured Query Language (SQL)

after that.. i need to crack my head to update 3 tables simultaneously if changes are done or else update certain tables out of the 3 tables considering efficiency and resource usage.. -.-

erm... Joining 3 tables into 1?

Me joining 10 excel sheets database into 1 then process and filter them summore using Macro...

Lots of Loops involved... :P

hm.. joining 3 tables should still be fine, and it's commonly seen in a normalized database structure. If outer join comes in, then it will be a little bit tedious, depending on the DBMS.

Remember to update more than 1 table simultaneously as a transaction, to ensure data consistency ;-)
