Databases and web

A.Y. 2021/2022
Overall hours
Learning objectives
The course learning objective is to illustrate the main data management concepts and methodologies, focusing in particular on relational databases, the SQL language, and their role in Web architectures. Also, it has the objective to provide a hands-on experience to acquire the ability to implement a Web portal that dynamically gets data by querying a relational DBMS.
Expected learning outcomes
The students are expected to understand the relevance of appropriate data representation and management. They will learn how to design a relational DB, and how to use SQL to query and manage the data. By the hands-on experience they will also learn how to implement a dynamic Web site that acquires data by querying a relational DBMS.

Prerequisites for admission
The course requires knowledge of the basic notions of computer science, including computer architecture and operating systems, in addition to the ability to write programs in at least one programming language and the knowledge of HTML.
Students that have not passed the Programming course exam will not be admitted to the exam of this course. Students are strongly encouraged to pass the exam of Web and Cloud Applications before taking this course.
Teaching methods
The theory part consists in frontal teaching with slides, examples and exercises. The interaction with students is stimulated with questions and online quizzes.
The lab part alternates frontal teaching with individual practical activity in a computer lab.
Teaching Resources
Basi di dati: Modelli e linguaggi di interrogazione 4/ed, Paolo Atzeni, Stefano Ceri, Stefano Paraboschi, Riccardo Torlone, McGraw-Hill, 2013, ISBN: 978-88-386-6800-5
Assessment methods and Criteria
The evaluation of the students' profit for this course consists of two parts. The first part concerns the fundamental notions (theory) and is organised in a written test including a multiple choice quiz on all the topics covered in the theory module, followed by three kinds of exercises (open questions). This part is evaluated with a score from 0 to 32 with 18 as the minimum score to pass this part and be admitted to the lab part.

The abilities acquired in the lab module are evaluated by assigning an individual software project that can be prepared at home but will have to be modified at school during the final lab exam that is usually held 7-10 days after the theory part. Even in this case the student will obtain a score between 0 and 32 with 18 as the minimum score to pass.

The final score is obtained with a weighted sum (2/3 for theory and 1/3 for lab). The resulting score is the final with ay score above 30 registered as '30 with honor'.
