Hi Sudheer, First of all there a number of ways to design this database.
You will need to choose the one that you feel suites your needs best. Here one possible design. Because you have different type of users/accounts, it looks like "ACCOUNT_TYPE" table is needed ACCOUNT_TYPE table Account_type_id - autoincrement, PK Account_type - varchar(25). ( Values in this field are: "Individual","Business","Partner","Internal") Because you have user information to store: USER_INFO table User_id - autoincrement, PK Account_type_id - integer, FK (foreign key to ACCOUNT_TYPE) Fields of personal/Business information to follow - (First, Last Name, .....) Because you have web site security info to store: WEB_SITE_SECURITY_INFO table User_id - integer, FK (foreign key to USER_INFO) Security_question Security_question_answer Fields of security information to follow You can grow the database as you add module, but as much as you can foresee and design ahead it would be better Mikhail Berman -----Original Message----- From: Sudheer Satyanarayana [mailto:[EMAIL PROTECTED] Sent: Thursday, June 14, 2007 1:50 AM To: mysql@lists.mysql.com Subject: Design Help Needed Hi, I'm creating an application for my web site. I want help in designing database tables. Currently I'm starting with user management system. The web site would have these types of users 1. Customer account 1a. Individual account. This user would be an individual with username, password, billing address, account security question, answer and few more fields. 1b. Business account. Each business account would have many users. Currently I have not decided the number of users for this type of account. It may be 10 users in the beginning. I want to keep an option to increase the number of users for business accounts. The business account will have, business name, billing address, account security question, answer, and few other business details. Each user within the account will have username, password, first name last name, mobile number and other personal details. 2. Partner account. These are similar to 1b business account type. 3. Internal account. These are employee accounts. Each user will have username, password, first name, last name, department, phone number and few other fields. Ideally how many tables should I create? What are the types of keys(primary and foreign) Other modules of the application I would be developing in the future are, contact management, shopping cart, mailing lists, customer support, etc. I have MySQL 4.1 on the server. Hope my question is clear. PS: I'm new to databases. Thanks for the help, Sudheer.
