07. Laboratory activities:
07.01 Introduction to MySQL on the Linux operating system.
07.02 Architecture of the MySQL server and client.
07.03 Development MySQL database driven.
07.04 Access to MySQL database using PHP.

Although there are no mandatory prerequisites for this exam, students are strongly recommended to take it after Algorithms and Data Structures, Computer Architecture, Procedural and Logic Programming.

It is also worth noticing that the topics covered by this course will be used in Integrated Geographical Databases.

Teaching

Theory lectures and laboratory exercises, both face-to face and on-line.

Attendance

Although recommended, course attendance is not mandatory.

Disability and Specific Learning Disorders (SLD)

Students who have registered their disability certification or SLD certification with the Inclusion and Right to Study Office can request to use conceptual maps (for keywords) during exams.

To this end, it is necessary to send the maps, two weeks before the exam date, to the course instructor, who will verify their compliance with the university guidelines and may request modifications.

The course is offered both face-to-face and on-line within the Laurea Degree Program in Applied Computer Science.
