DJBEAT.NET SQL DATABASE

Nathan Perkins

Project Description

A database for my online Social Network website – DJBeat.net

Site is used by music producers, disk jockeys and digital artists

Site allows users to upload their own music, videos and pictures and create a user profile for other users to view

Outcomes

5 tables created

Account Photo Videos Music Profile

photosphoto_id: int

account_id: intphoto_name: varchar(30)photo_size: varchar(10)date: datetimedescription: varchar(100)

videosvideo_id: int

account_id: intvideo_name: varchar(20)video_size: varchar(20)date: datetimedescription: varchar(50)

profprof_id: intaccount_id: int

about_me: varchar(300)hobbies: varchar(300)birthdate: datetime

accountaccount_id: int

first_name: varchar(20)last_name: varchar(20)artist_name: varchar(20)occupation: varchar(20)record_label: varchar(20)email: varchar(30)

musicmusic_id: int

account_id: intsong_name: varchar(20)file_size: varchar(20)date: datetimegenre: varchar(20)track_number: varchar(2)

Outcomes

Created a Join to display each users uploaded multimedia

This join could be used either by site admin to determine disk usage or by user to view a summary of all files

Outcomes

Created a Join to display every active user and a summary of user info

This join could be used either by site admin to determine bandwidth required, or by user to see who else is a site member

Lessons Learned

It is messy to use user as the name of a table.

Forward engineering a database with a user table is catastrophic

Always copy and paste SQL code into notepad as a backup
