A soccer team has 22 players. Every player has a rating, namely Beginner, Intermediate and Advanced. Rating levels have dedicated skill levels. For Beginner level, 1, 2 and 3; for Intermediate level, 4, 5, 6, 7 and for Advanced level, 8, 9 and 10 are skill levels. We need to store Teams (name, city, players, total points in the season and standing in the season), Players (name, surname, number, scored goal in the season, rating level and skill level) and Matches (date, time, place, teams, winner and score) in a database. 1. Draw an E-R diagram for this relationship. You will draw E-R diagram on a paper by your hand (If you dont draw it by your hand, you will get 0.). Use the E-R diagram format that we learned in the class. Take a clear photo of your diagram and insert it into Word file. You can use this assignment file as an answer paper. 2. In the same Word file, draw the tables with attributes by highlighting primary keys. If you think that there are more tables needed because of normalization, create and provide justification. Show all of the functional dependencies. Start from non-normalized form and progress towards 3NF form for better design. Draw the tables for 1NF, 2NF and 3NF. 3. Create tables by SQL queries. Write SQL statements into the same Word file to create those tables. I will check your SQL statements. If they dont run smoothly, you cannot get any score from erroneous queries. Check your SQL statements here: https://sql.js.org/examples/GUI/index.html Notes: - We did a lot of examples in the course. Refer to the lecture slides for formats and approach. - Submit only one file in .docx format (Microsoft Word file). - Please do whatever as requested. Don't make up your own format. - You can provide your assumptions and justifications whenever it is needed. - Do not add any additional tables, relations or attributes except for those needed for normalization.
