Creating and using XML Web Services

Version A

Football league results and standings

• Create and store in a file of chosen format the data from a football season:
• the number and the names of the teams in the league
• the dates and results of all the games (there are two games for each pair of teams, in each game the different team plays home)
• make sure the season is split to two rounds (spring and autumn), in each round two teams play only once
• Create a XML Web Service at the address: http://localhost/task6/DLS/DLService.asmx
  • methods:
    • GetSeasonInfo
      • returns the season information
        • teams taking part in the league games
        • season and rounds start and end dates
    • GetGamesInfo
      • returns the game information for all games played at given date
      • team names
      • result
      • make sure that the exceptional situations (e.g. no games played at given date) are properly handled
      • the numbers and types of parameters as well as the type of the result are arbitrary
      • use the data stored locally
• Create an ASP.NET application which contains a page at the address: http://localhost/task6/DLT/DLTest.aspx
• the page contains:
  • an edit control for giving the date
  • a dropdown box for choice between spring and autumn rounds, or entire season
  • a league table for the given period of time (from start of the round / season until the given date)
  • a team gets 3 points for each win, 1 point for draw and 0 points for loss
  • for each team there is given: number of games played, number of points, number of scored goals and number of goals lost
  • the teams in the table are sorted by a number of points, and in case of equal number of points, by the difference between scored and lost goals
  • if there is no date given, the data provided comes from the entire round / season
  • a button for refreshing the table
• as the data source, use the functions from the created service
• CAUTION: if the addresses of the Web Site and Web Service are different than these provided above, only the "potential usability" of the code will be marked
