Well, yes there are. It is very likely that you will want to name subsequent database objects which are closely associated with that table (indexes, constraints, etc) with the table name as the prefix (or suffix). The longer your original table name, the less flexibility you have before you have to start amending or truncating your table name. Depending on your working practices, this could be inconvenient if you want to retain the original table name as a key component of other object names. We do just this
(corporate standards), and these standards enable us to by-pass many joins
across the Oracle DD when looking for dependencies etc.  

just a thought

Are there any issues to consider when naming tables and/or columns (length of column name)? I know the max length is 30 but some of the table names that my client wants to add (against my recommendation) look like Cobol and are pushing 30 characters.

Just wanted to know if there are any potential performance issues or anything else I should warn them about.

Thank in advance!
