Diff between xxx_data.mdf and xxx.mdf files

What is difference between "xxx_data.mdf" and "xxxx.mdf"? IN Sql2k, I create
d, attach and detach database manytimes. SOme time its shows the database fi
le name as "xxx_data.mdb and xxx_log.mdb" and sometimes it only shows file n
ame as "xxx.mdf and xxx.ldf", why? However in Enterprise manager it shows da
tabase na as "xxx".
I just want to know difference these file name conventions, what was the log
ic behind this?

Version: 6.0.715 / Virus Database: 471 - Release Date: 07/04/2004There is no special significance to the suffixes _data and _log. They are
just the naming conventions used when the database was created. You can name
database files as anything you like, however the standard extensions for SQL
Server files are .MDF for data files and .LDF for log files.
MDB is the standard name for Access databases and isn't normally used for
SQL Server files.

clearly has nothing to do with DTS, Clients or Connections so why post
there?)

just what the naming convention was at the time the databases were created.
The actual database name is independent of the file name (and a database ca
n consist of multiple files anyway, so it wouldn't make much sense to name t
he files after the database).
