Here are my requirements,

i have around 5000 backup file(full database backup) for the last 2 years.No i wants to create a data warehouse(simple) for my database.

my initial tables are
1. item(id,description)
2. category(id,name,pid)

and there is a column changes occurs in different version of my database... for example when the image functionality is added to we have changed the table item(id,description) to item(id,description,image_link)... and so on.

now i wants all the items information for the last 2 years(using 5000 backup files)

what will be the process?
any sample scripts are highly appreciated.

Thanks

[
from my observation ...
Procedure may be...

[*] create new database for warehouse purpose and another one for restore purpose.

[1] use current item table structure

[2] column should support null
(current_tables_columns-initial_tables_columns)

[3] extra one column for database version(i.e .bak file name)

... here i might use cursors for looping purpose of my backup files(5000)

[4] restore one database

[5] if new id then
insert new record
else
update previous record

I'm new to administrating please help me!
