Homeworks

Rules

To obtain the points associated with the home assignments, students must observe the following terms:

• Complete all the points of the exercises in the homework text.
• Prepare a file in PDF, DOC or ODT format with the solution of the homework.
• Name the file as HomeworkN_Surname_Name_StudentId.XXX, where
  • StudentId, Surname and Name should be replaced with student information
  • the N character following Homework should be replaced with the number of the submitted homework (e.g., ‘1’ for homework no. 1)
  • the filename extension XXX depends on the file type chosen for the submission (PDF, DOC or ODT).
  • the DOCX format is not supported.
  • Since uploaded files are automatically processed, naming the file with a wrong name implies the cancellation of the related homework submission.
• Load the file on the didactic portal (Portale della didattica) in the section Work Submission (Elaborati) before the deadline.
  • Multiple loadings for the same student and/or for the same homework are not allowed.
  • The upload date shown on the didactic portal is considered for the evaluation.
  • Since uploaded files are automatically processed, the upload after the deadline implies the cancellation of the related homework submission.
• During the upload procedure a description (“Descrizione”) field is required. Insert the same name given to the uploaded file (according to the rules described above).
• Only for students with no access to the course page on the didactic portal, the homework may be submitted before the deadline by sending an email to the assistant lecturer.
• Discuss the homework with a positive evaluation on the fixed date (announcement will be published).
• Homework #4 note: The delivery of the realized code must be done via upload on the portal as for the files of the previous homeworks. In this case, however, each student will have to upload a single .zip file containing the developed code.The archive should follow the same naming convention given above. The archive must contain:
  • all .php and .html files created for the application
  • a file named create_and_populate_database.sql (content described in the homework text)
    
  • a file named interrogation_and_transaction.sql (content described in the homework text)
