社交网站所需的数据库架构帮助

Question

I'm in middle of creating a social networking site something like facebook, and got struck up with database schema design for it.. from previous questions i posted here, i confirmed that i cant create new database or tables for a new user who registers onto my site. I need to insert new row [thats my only option(correct me if i'm wrong!)]. but, this works out for registration for the first time. what if the user posts something new on his profile.. where should i insert this update.. coz, i cant insert them into rows as dey correspond to each user.. and too many columns cannot be created.. what is the solution for this.?

schema =>

TableName : User_content

userId Name College City Status_Updates Messages

1 a sfd fds fsds sdds 2 f dfg dfd fdf dfd

what if user 1 updates something.. what i need to do nw. Think its a status update, how to go about it.?

Before you start thinking about this social network site you dream if Developing you need to understand database modelling fundamentals. This link will help you with some simple concepts. http://www.databaseanswers.org/tutorial4_data_modelling/index.htm

Answer 2

Add tables based on what you want to allow your users to do and the related data you need to store as a result. Some example tables:

• 'user_account': User account information (e-mail address, password) - referenced by user ID
• 'user_profile': Basic user profile information - referenced by user ID
• 'user_status': User status message - referenced by user ID

I have the sense that this is your first major database application, and if so, you need to learn more about database design in general before you take on creating an application like this. There are many things to consider when designing a database schema and designing it well from the start is key. The core of your application will rely on how well your data is organized and accessible, so ensure you spend enough time developing a good design.

Good luck!
