TPS Database storage structures (1 Viewer)

[stoydgen]

Hey guys just curious if im gonna need to know about the different database storage structures IE
*Sequential data Storage
*Indexed Sequential Data storage
*Hashed file storage

I see it in my jacaranda palm cards, but not in the heinmann text book (not thats it would anyways, considering how crap it is lol)

Cheers.

i've heard of sequential data storage

but the other two, never seen them before
well i used heinman for ipt and only that
it is quite a good text!

hmm, i honestly doubt you need to know the other two

Just get the basic idea. I suppose you are getting these from the Jacaranda book? Last year i talked to hsc advice line teachers and one of them told me that Jacaranda is written from a perspective of students doing both ipt and sdd. Thus it contains extra stuff. I spent ages learning the 3 searches you mentioned but wasnt worth it. as i said...just get the basic idea.

Good Luck in your hsc.
btw when is it?

yes all three methods are important i have looked at papers well my teachers says the questions she gave us are from past papers and you need to know the three methods of storage and retrieval of digital files.
