Project Description In this project, you will design and implement a database for keeping track of information for an online “SOCIAL NETWORK” system (e.g. a simplified version of Facebook!). You will first design an EER schema diagram for this database application. Then, you will map the EER schema into a relational database schema and implement it on ORACLE or MySQL or some other relational DBMS. Finally, you will load some data into your database (via user Interface) and create some...
