9793926 - DATA BASE AND BIG DATA ANALYTICS
Modulo BIG DATA ANALYTICS

This module covers the fundamental concepts of management and design of a business intelligence system. 

Topics include data models for building a Data Warehouse; ETL (extract, transform, and load) pipeline; Data Lake and ELT pipeline; OLAP analysis; basic data mining; reporting and interactive dashboards; evolution of BI architectures on large datasets.
The module covers techniques and algorithms for data visualization and exploratory analysis based on principles and techniques from graphic design. It is targeted at using visualization in their data analytics work.
The learning objectives are as follows:

Knowledge and understanding

• To understand the most important methodologies and techniques used by industries to analyse data to support the decision process
• To understand the main methodologies for designing a data warehouse
• To understand the main methodologies to transform data into sources of knowledge through visual representation

Applying knowledge and understanding

• To be able to apply methodologies and techniques to analyse data.
• To be able to design a data warehouse.
• To be able to build reports and data analysis and organize them into interactive dashboards

Making judgements
