Hi,
First of all thank you for your reply.
The table names I've wrote in the e-mail were just for info, I do
use underscore instead of space, as you can see I do the same for the
fields in the table.
In theory it is simple but I need some help on how that will be
"translated" to mysql, I have a concept in mind, but I do not know how
to exactly apply it to the situation.
I am in a situation where I have the data gathered from more persons
and everybody had a personal way of designing the database or excel
table and now I need to build a database that will include all the data
in the tables bellow, that is way I was not able to give you a table
description from mysql since I do not have all the tables imported into
mysql.
After I will import the tables into mysql I have to make somehow the
new table and I would like it to be good, and that it can be further
upgraded ( maybe a new service will need to be entered for a customer
and I need to have all the data in one place ) and to be able to handle
each entry not by using 4 fields that are varchar.
If you / someone can help me with this task I will be very grateful,
as I have said before I am a beginer and do not have much experience
with MySQL.
Best regards and thank you for your advice,
Cristi Stoica
