Hi esso, welcome to AWF...
I'm not sure what you mean? If you mean do you need to prefix field names with something in a table, then you could add the prefix fld so a field you named "MyField" would become:- fldMyField... It's not strictly necessary to do this, and many don't. However one of the advantages of using a prefix is, you can ensure that you never accidentally use a reserved word.
If you mean should your table names be prefixed with tbl, then yes, this is considered good practice and again it gives you the benefit of avoiding accidentally creating tables with a reserved word as the name of the table. It also helps you identify what you are referring to in your code...
