Database Development and Applications in Biology


Introduce the fundamental concepts inherent to the development of relational databases aiming to support the implementation of transactional systems. This curricular unit places great emphasis on a theoretical structuring of knowledge combined with the provision of extensive practical experience based on the use of Relational Database Management Systems (RDBMS) and data modeling tools. In practical cases, particular emphasis will be placed on data modeling, information extraction, and business rulemaking in functional contexts within Bioinformatics. This course should provide students with the skills of structuring information as well as using the SQL language for querying databases and programming business rules.

Teaching method

The course unit is organized in theoretical classes and practical classes, equally distributed throughout the semester. The slides and the writing on the board are the main pedagogical instruments used in theoretical classes, although in some cases the installations are integrated with the use of more sophisticated technologies such as graphic or multimedia interfaces. Practical exercises using modeling software and DBMS exploration software will be the main pedagogical tools used in practical classes. A substantial part of the practical classes will be devoted to group work.

Evaluation method

The evaluation is obtained by a weighted average between the average grade obtained in a set of assessments during the semester (30%), a group work (30%), as well as a final exam (40%).
