of at least six tables populated with data The database is to support queries that would typically be submitted to the system for the topical chosen area Using Chen’s Notation for Entity Relationship Diagram (ERD) Map the EER model into a relational data model normalized at least rd normal Form Using appropriate SQL commands create a set of database tables in MS SQL Server 2008+ You should also show all constraints used in the creation of the tables II Specification: Your database must contain one view, one trigger, on store procedure and an index (describe why) Create 10 sample queries that demonstrate the expressiveness of your database system Your queries must demonstrate different aspects of the system III Destination Design and develop a database system for English Premier League 2017 – 2018 IV Tools Microsoft SQL Database Management Studio 2016 Microsoft Visio 2016 Professional Microsoft Word 2016 Professional https://www.generatedata.com Page B Preview I Introduce The Premier League The Premier League is an English professional league for men's association football clubs At the top of the English football league system, it is the country's primary football competition Contested by 20 clubs, it operates on a system of promotion and relegation with the English Football League Welsh clubs that compete in the English football league system can also qualify Welsh clubs that compete in the English football league system can also qualify The Premier League is a corporation in which the 20 member clubs act as shareholders Seasons run from August to May Teams play 38 matches each (playing each team in the league twice, home and away), totaling 380 matches in the season Most games are played on Saturday and Sunday afternoons; others during weekday evenings It is colloquially known as the Premiership and outside the UK it is commonly referred to as the English Premier League (EPL) In total, 49 clubs have competed since the inception of the Premier League in 1992 Six of them have won the title: Manchester United (13), Chelsea (5), Arsenal (3), Manchester City (2), Blackburn Rovers (1) and Leicester City (1) Figure 1: The Premier League Information (Source: Wikipedia (https://en.wikipedia.org/wiki/Premier_League)) Page II Information for a Premier League Season A Premier League season contains a lot of information that must be stored Below is the most necessary information: • Fixtures • Results • Tables • Clubs • Players • Managers • Referees • Match statistics Figure 2: Premier League Season information In fact, a Premier League season has much more information than above one such as broadcast rights, transfers, tickets, safeguarding or lots of other However, to simplify the work of designing and developing databases system as well as the structure of database, I will only concentrate on the main information that I listed above (Source: https://www.premierleague.com/home) Fixtures In order to control the matches time for broadcast, transfers purpose or fitting with all other events like Christmas, New Years, World Cup Qualifiers, etc., before the first game, the fixtures are made for a whole season – usually from August to May The fixtures contain lots of records Each record includes information of a match that has been scheduled: home team, guest team, date and time that the match will be played, the stadium where the match will be hold Page Figure 3: Premier League Fixtures (Source: https://www.premierleague.com/fixtures) Results: Results is one of the most information of a football match The results are the status win, lose or draw, the score of home and away team The winner will receive points, the looser will get no point and if the result is draw, both two team get point Page Figure 4: Premier League Results (Source: https://www.premierleague.com/results) Tables After a match, each teach will get their corresponding point (3 points if win, point if draw and point if lose) This point will be statistics to create tables The tables will be updated after a match and will show ranking of each team in the league The tables usually contain club name with their position, how many game that played, games they won, drawn and lost, number of goals for, goal again, goal different, their point and their recently form Page Figure 5: Premier League 2017 – 2018 Tables (Source: https://www.premierleague.com/tables) Clubs In the Premier League history, there are many different clubs that had competed at this league, but in this assignment, I will only concern about the most recently season, the Premier League 2017 – 2018 So, there are only have 20 clubs compete at this league this season A club information includes their name, their address, their stadium, their CEO, etc
