Database Design

We used 9 tables to design our database. First 4 table (City , City_Match, Date_Match, Person) are common table.They are used in relative pages.

• City

• City_Match

• Date_Match

• Person

• Concert

• Exhibition

• Fair

• Movie

• Theatre

City Table

Fig. 2.1: City Table

In this table we keep id and name of cities. Because there are certain number of cities in Turkey and when a tupleis created for concert, theatre... ext. we have to initialize the city column. Therefore, we created a table city andwe kept all cities in Turkey.

Table contents are like this;

17


There is a part of all cities that figure shows:

City_Match Table

In this table we kept countries of events.

CId for city Id,EvId for id of event and EvType for event type type(Theatre=1, Movie=2, Exhibition=3,Fair=4,Concert=5).

Table content like this;

Here is sample of some city match.

Date_Match Table

This table keep data of which event is on which date.

Table content like this;

Date match of all events are kept in this table.

Person

In this table we kept the people who are directors, writers and musicians. We defined an id for every person andname of the person.

The figure above shows some samples of person table.

E/R Diagram

Code

There is an initalization button for database in Home Page that makes possible to reset all datas according to‘init.sql’ file.:

public class HomePage extends BasePage {public HomePage() {

Form initForm = new InitForm("initForm");this.add(initForm);

}}

There is the class of Navigation bar :

Fig. 2.3: Person Table

Fig. 2.4: Contents

2.2. Code 19


Fig. 2.5: E/R Diagram of Database

public class NavigationPanel extends Panel {public NavigationPanel(String id) {

super(id);}

}

We defined all cities in Turkey for all developers to specify the places of their events and Navigationbar is addedto Basepage. All pages that we created are extended from ‘BasePage.java’:

public class BasePage extends WebPage {protected static final long serialVersionUID = 1L;protected static final List<String> Cities = Arrays.asList(new String[] {

"Adana", "Adıyaman", "Afyon", "Agrı", "Amasya", "Ankara","Antalya", "Artvin", "Aydın", "Balıkesir", "Bilecik", "Bingöl","Bitlis", "Bolu", "Burdur", "Bursa", "Çanakkale", "Çankırı","Çorum", "Denizli", "Diyarbakır", "Edirne", "Elazıg", "Erzincan","Erzurum", "Eskisehir", "Gaziantep", "Giresun", "Gümüshane","Hakkari", "Hatay", "Isparta", "Içel", "Istanbul", "Izmir", "Kars","Kastamonu", "Kayseri", "Kırklareli", "Kırsehir", "Kocaeli","Konya", "Kütahya", "Malatya", "Manisa", "K.maras", "Mardin","Mugla", "Mus", "Nevsehir", "Nigde", "Ordu", "Rize", "Sakarya","Samsun", "Siirt", "Sinop", "Sivas", "Tekirdag", "Tokat","Trabzon", "Tunceli", "Sanlıurfa", "Usak", "Van", "Yozgat","Zonguldak", "Aksaray", "Bayburt", "Karaman", "Kırıkkale","Batman", "Sırnak", "Bartın", "Ardahan", "Igdır", "Yalova","Karabük", "Kilis", "Osmaniye", "Düzce" });

protected static final List<String> FairTypes = Arrays.asList(new String[] {"Ihtisas Fuarı", "Uluslararası Ihtisas Fuarı" });

protected static final IModel<String> defaultCity = new Model<String>("Adana");

public BasePage() {this(null);

}

public BasePage(IModel model) {super(model);



this.add(new NavigationPanel("orangeNav"));}}

This class below makes it possible to ensure the connection of our database and wicket application :

public class ConnectionDB {public static Connection conn = null;

static {

try {Class.forName("org.sqlite.JDBC");String homeDir = System.getProperty("user.home");String dbFilePath = "jdbc:sqlite:" + homeDir + File.separator

+ "Events.sqlite";if (conn == null) {

Locale.setDefault(new Locale("tr", "TR"));conn = DriverManager.getConnection(dbFilePath);

}

} catch (Exception e) {System.err.println(e.getClass().getName() + ": " + e.getMessage());System.exit(0);

}System.out.println("Opened database successfully");

}}

InitForm class defines the initilization button for database :

public class InitForm extends Form {

public InitForm(String id) {super(id);this.add(new FeedbackPanel("feedback"));

}

public void onSubmit() {WicketApplication app = (WicketApplication) this.getApplication();ServletContext context = app.getServletContext();InitDatabase IDatabase = new InitDatabase();IDatabase.Initialize(context);info("Initialize Edildi.");

}}

We created About Page and Cantact Page without using any Java method. Arrangments are made in html.

public class AboutBasePage extends BasePage {public AboutBasePage() {}

}

public class ContactBasePage extends BasePage {public ContactBasePage() {}

}

WicketApplication class makes it possible to connect all the pages which are Concert, Theatre, Homepage, Fair,Cinema, Exhibition, Contact and About.

2.2. Code 21


public class WicketApplication extends WebApplication {public void init() {

super.init();mountPage("/Concert", ConcertBasePage.class);mountPage("/HomePage", HomePage.class);mountPage("/Theatre", TheatreBasePage.class);mountPage("/Fair", FairBasePage.class);mountPage("/Cinema", MovieBasePage.class);mountPage("/Exhibition", ExhibitionBasePage.class);mountPage("/Contact", ContactBasePage.class);mountPage("/About", AboutBasePage.class);

}

public Class<? extends WebPage> getHomePage() {return HomePage.class;

}}

Theatre Page

Theatre Database Design

Theatre Table

Fig. 2.6: Theatre Table

In this table we kept data for id, title, writer id , city id, capacity of saloon, available ticket and status of theatre isdeleted or not.

Table is created like this;

Here is some samples of theatres:

Code

Theatre class consists of Id, Title, Writer, City, Capacity, tDate, AvailableTicket and Deleted.:



Fig. 2.7: Theatre Michelangelo which has an id 1 has a writer named Irmak Bahçeci where Id = 1. City of theevent is Istanbul (CityId=34) and capacity of theatre is 100. All tickets are available because the number of it isequal to the number of capacity.

public class Theatre {public Integer Id = null;public String Title = null;public String Writer = null;public String City = null;public Integer Capacity = null;public Date tDate = null;public Integer AvailableTicket = null;public Boolean Deleted = null;

public Theatre() {}

}

TheatreBasePage shows all theatres without filtering and makes it possible to filter the thatre events. It providesto add new theatres to database.

Movie Table

Fig. 2.8: Movie Table

Movie table keeps data for movies. Id of movie, title of movie, director id of movie, year of movie, city id ofmovie ,score of movie, place of movie, capacity of movie, available ticket of movie, and status of movie (deletedor not) are kept in the table.

Table contents are initialized like this;

Sample of some movies are in the below:

Code

Movie class consists of DirectorName, Id, Title, DirectorId, Year, FilmName, Score, AvailableTicket, Capacity,Place, City, Deleted, StartDate, EndDate and date.:

public class Movie {public String DirectorName = null;public Integer Id = null;public String Title = null;

2.2. Code 37


Fig. 2.9: Contents

Fig. 2.10: There is a movie which has the id 1 and named like Metropolis. Director id is 50 and that meansdirector’s name is Fritz Lang. Production year is 1927 and movie is showing in Pera Müzesi / Istanbul (CityId=34).Score of movie is 8,3 and capacity of saloon is 100 and there is 100 available tickets.



public String FilmName = null;public Integer DirectorId = null;public Integer Year = null;public Double Score = null;public Integer AvailableTicket = null;public Integer Capacity = null;public String Place = null;public String City = null;public Boolean Deleted = null;public Date StartDate = null;public Date EndDate = null;public Date date = null;

Fair Database Design

Fair Table

Fair table keeps information about id, name, fair type, place, capacity, available ticket, city id and deleted statusabout a fair.

Fig. 2.13: Fair Table

Table contents are like this;

Here is samples of some fairs;

Code

Fair class consists of Id, Name, City, FairType, Place, Capacity, AvailableCapacity, Deleted, StartDate and End-Date.:

2.2. Code 59


Fig. 2.14: There is a fair named ‘Kitap Fuarı’ that has Id =1. Fair type is ‘Ihtisas Fuarı’ and place of the fair isAto Kongre Sarayı in Ankara (City id=6). Capacity is 29 and there is 29 available tickets.

Concert Database Design

Concert Table

Concert table keep data of a concert which are id, musician id, place, capacity, available ticket, city id and deletedstatus.

Creating table like this;

Some tuples of concert;

Code

Concert class consists of Id, MusicianId, MusicianName, date, Place, Capacity, AvailableTicket, City andDeleted.:

2.2. Code 69


Fig. 2.15: Concert Table

Fig. 2.16: There is a concert of Metallica (Musician Id = 100) in Istanbul (City id =34) that has the capacity 100and 100 available tickets.
