Knowledge of basic computer science.
The course aims at providing the students coming from the humanities with the basics of Database Design. A particula focus will be placed on theories and tools that have become fundamental in their field of interest.
The following topics will be taught:
- Databases and Database Users
- Database System Concepts and Architecture
- Data Modeling Using the Entity-Relationship (ER) Model
- The Enhanced Entity Relationship (EER) Model
- The Relational Data Model and Relational Database Constraints
- Relational Database Design by ER- and EER-to-Relational Mapping
- Basic SQL
The student will be able to understand data model, to interact with existing databases and to collaborate with software engineers to design data-centric applications. Such skills will prove useful in other courses (ex. web technologies) to design online applications and online services for humanities.
Frontal lessons and lectures, for theoretical aspects, will be followed by participatory learning sessions and hands-on sessions to reinforce the comprehension and to acquire the abilities relevant to field of database design.
The evaluation consists in the presentation of a project related to the design of a database. The project consists in the design of the Entity Relationship and of the Relational model and in the implementation of the Database with MySql language.
