Armazenamento e Recuperação de Dados


Today, data is everywhere and come in different shapes and volumes, in structured and unstructured forms. Companies need to store and manage these data using appropriate data management or database technologies for the success of their business processes. In the Storing and Retrieving Data course, students will get familiar with the architecture of a DBMS, the process of database modelling and normalization, the implementation of a relational database using SQL language (theoretical and practical), use of advance SQL objects as Views and Triggers, integration of different data sources using ETL operations, and the advantages and disadvantages of SQL and NoSQL databases.
