Bloated SQL Server 2000 database

Hello -- I have a database that is 102GB in size. It has been growing
expotentially every month for the past couple of years. Since we have a
bunch of similar database, we did not understand why this database was so
much larger than the other databases, considering roughly the same
kind/amount of data is imported each day.
I've run various DBCC CHECKALLOC, DBCC CHECKDB, and DBCC CHECKCATALOG
commands and DBCC DBREINDEX commands to see if I can find any problems. No
errors are being reported and recreating all indexes did not do change size.
I have since created a new database and used DTS to export/import all
data/rows from old database to new database.
I then rebuilt indexes.
The new database size is now only 2.6GB!
I still have the old database and want to determine what is messed up within
it to cause the size to be so large and continue to grow each month.
Does anyone know of anything else I can check or do to determine my space
allocation issues?
Any help or commands would be appreciated.What is the recovery mode of your old database? Is it set to full? If so,
are you backing up the transaction logs? What kind of backups do you do on
this database?

you are running the Simple Recovery model. Under Full Recovery your log
will grow until you back it up.
Check the output of EXEC sp_spaceused. If the extra space is unused you
can use DBCC SHRINKFILE to free the space on disk.

Probably, you had some large tables in the database at some point which
caused the data files to auto-grow to their current size. If you run
sp_spaceused from the database, you'll see the unallocated space in the
data file. If you see large amount of unallocated space, you can shrink
the data file (off-hours) using DBCC SHRINKFILE to recover the lost
space (but leave enough to avoid auto-grow ops if possible).

I ran a SHOWCONTIG and it looks like it is fragmented due to a few large
tables not having a clustered index.
I'm going to create a clustered index on table so it can reorganize the data
pages and see if my size problem shrinks.

found out that my databse was heavily fragmented. So I ran DBCC INDEXDEFRAG
on all of the tables with more than 10 pages, and then did a Shrink Database

I should note that all of the tables had Clustered Indexing on the primary
key, but not on the other keys (if any).
Hope this helps.

the database is less than 1GB.
I use Diskkeeper to defrag the hard drive on the server and I noteced that
the disk became heavily (58%) fragmented AFTER I ran INDEXDEFRAG and Shrink
Database.
Just thought I'd point that out in case you're concerned about disk
fragmentation.
