Dear Jerry Schwartz
We have applications for colleges in India. The same idea of having single table for
manipulating students records. but we are not following archiving concept.
Ex stupersonal. and stuclass these tables are playing wide role in our application. After
7 years now there are 9000 records[postgresql backend] are there in the table. Because of
this the entire application [ Fees, attendance, exams etc] performance is getting down.
For the remedy of this I proposed this year wise architecture for our new version [mysql].
I have problem in year wise also, i have number of mutual related tables for students such
as stu_last_studies, stu_family_details, stu_address, stu_extracurri and so on. If i go
for year basisis i have to make all the above tables also year basis.
Hence, I feel it difficult have such number of tables after few years.
As you said the archive system, can you the idea about the archive system[If needed i will
give the table structures].
It will be grate help to me.

[JS] It sounds like you are planning to have one table per year. Regardless of
where you put your blobs, I think that is a bad idea from a design standpoint.
It will make it harder to find historical information.
If your database is relatively small, then I'd just keep everything in one
table. If it is big, then roll data that is five years old into an archive
table. That will give you only two places, and an easy-to-follow rule to tell
you where to look.
