Hmmm. Seems I have to play devil's advocate on this one. So, you see no purpose to
index names such as:
P_EMPLOYEE for a Primary key on the employee table
or UM_METER_CODE for a unique index on the meter table meter_code column
or FE_DEPT for a foreign key index on the employee table dept column
or IIE_LOG_DATE for a non-unique index on the import_export table log_date column?
The first letter doesn't help me figure out that the object is an index, but it sure
helps to show what the index is being used for.
Constraint naming is another area where we use a one character prefix to identify the
constraint type, in part to conform to index naming.
The keeper of standards here (not me) has also imposed prefix conventions on global
temporary tables and on selected classes of tables such as work tables or external
cross reference tables. It does help keep the developers in line.

You already know it's an index, why would you include that as part of the
name?

Subject: RE: Table Naming Conventions
My supervisor/client wants object types in names - except tables like I_
for indexes. Why do you say stay away from this?

Here's a start. Not a checklist by any means, just kind of a micro pet
peeves list.
* Decide today whether table names will be singular or plural. Do you
want a THING (singular) table? Or a THINGS (plural) table?
* Don't use case-sensitive names. E.g., use THING (without quotes) in
your CREATE (DDL) statement, which can be spelled "THING", "thing",
"Thing", or even "tHiNG" in your developers' SQL. But don't make
developers type stuff like this...
select "Name" from "Thing" where "Id" = y /* won't work without ""
*/
* Don't embed the object type in the object's name. I used to see this
all the time with tablespaces called XYZ_TS, indexes called IND_THING,
and so on.
* Decide today whether you want to abbreviate or not. If you do, then
construct a formal, standard, consistent list of accepted abbreviations.
Don't name one table CUSTOMER_THING and another CUST_HISTORY.

All...
Will some of you please provide some insight on your table naming
conventions? I'm in the very early planning stages of what will likely
be a large and complex schema (IT asset inventory). I have a chance to
start it correctly. TIA
