Thank you for your reply.
I took a look at your spreadsheet and immediately found a pretty nasty issue... about 2/3rds of the rows have duplicated Ticket Numbers.

Ticket response - can you have more than one response per ticket?
If Yes then its PK should be TicketResponseID and the Ticket Number should be a FK to Ticket
No,...

You can. That's the two choices for a code column: use a view to encode/decode and/or use a separate lookup table. A lookup table is technically a better design, but...

Hi Scott. Thanks for your reply. I understood most of what you said. I'd kindly like to ask for some clarification on some parts. But here is what I...

In general I agree, although in a truly normalized design the number of tables can get truly overwhelming (like SAP!).
Certain simple things do not need tables. Instead, you can use...

There are two main approaches:
(1) use a generic number for all codes, typically generated automatically by an identity column
So, type code = 1 might be 'Issue', = 2 might be...

Be careful! The problems with a generic lookup table, structured like this:
( table_id smallint NOT NULL, data_code varchar(50) NOT NULL, description varchar(1000) NULL )
are:
(1) the data_code (key) must be made...

This link gives a few reasons for choosing shorter varchar lengths.
In terms of storage, CHAR(n) columns are always n characters long.
VARCHAR(n) columns are anything between 2 and (n...

A large table, even a very large table, should not necessarily be slow.
You need to review the clustering key(s) on those tables. The clustered index key selection is the single...

Disk speeds on systems vary greatly. But you can always cancel the restore after (almost) 4 more hours. Cancelling a restore shouldn't take long at all, so you can wait...

No. 236GB is not bad for a 2.4TB db. Once the log has been preformatted, you'll be back to the regular restore of the data.

How large is the log file? SQL must restore the log file too, and, worse, it must preformat the entire log file before it restores to it. In essence, the...
