Designing DB's is an entire domain of study in itself!
However the rules (guidelines rather) I stick by at present but am open
to new ones as I need them,- are:
* Don't repeat data across tables (leads to 'data redundancy' = more
complex to update the DB)
* If in doubt 'put it' in a new table
* Use useful and memorable names for your tables and table columns
I do:
tablename_colname
Good luck!
