Learning outcomes This course introduces the theme of design, analysis and construction of the relational paradigm. Therefore, its main objective is to prepare students to understand, design and develop database systems.
The course focuses on the relational model, namely, modelling, normalization, query languages (relational algebra and SQL), database management issues and developing client/server database applications.
Upon completion of the teaching-learning process, the student should be able to:
- Given a real, or hypothetical case, develop a suitable data model;
- Normalize (3NF, BCNF, or a superior normal form) and "de-normalize" relations;
- Choose a database management system that fulfills the needs of the information system to be developed;
- Produce the physical database model;
- Query the database (using SQL);
- Develop multi-user database applications;
- Use transactions.

Teaching Methodologies and Assessment Criteria Classes are organized into theoretical classes (T), for the presentation of the program contents (slides and handwriting) and for interaction with students, and practical classes (PL), where concrete scenarios of using databases are exemplified and explored ( MS SQL Server).

Teaching Learning Classification (CEA) = Freq. (10 val) + Practical Work (5 val) + 5 mini-works (5 val);
Exam classification = Exam (15 val) + Practical Work (5 val)

Rating criteria:
By Frequency: CEA >= 9.5 val.
By Exam: when the sum of the Exam grade (quoted for 15 val) + Practical Work (5 val) is at least 9.5 val.
Language Portuguese. Tutorial support is available in English.
