Fundamentals of Big Data Training in Spain

The Fundamentals of Big Data course is a three-day introductory programme for professionals who want to understand Big Data technologies, Data Science concepts, and the data models that underpin modern analytical platforms.

The course is particularly suitable for organisations and technical professionals evaluating which NoSQL technologies and Big Data solutions may be appropriate for their environment. It also provides a strong first step for learners beginning a broader professional journey into Data Science.

Throughout the programme, participants explore different ways of modelling data, the core differences between SQL and NoSQL systems, and several of the major technologies used within the modern Big Data ecosystem.

Platforms including Neo4j, Hadoop, Spark, and MongoDB are introduced, with practical discussion of how they store, query, process, and analyse data.

The course also introduces fundamental Data Science concepts together with the mathematical and statistical thinking that supports analytical work. Participants learn how Python can be used to work with different data sources, interact with NoSQL databases through APIs, and support Big Data analysis.

By the end of the course, learners will understand the main technologies within the Big Data landscape, recognise different data modelling approaches, and have a clearer understanding of how Hadoop and Spark can be applied to large-scale analytical problems.

Participants should have:

• Previous experience using Python
• Experience working with data

Familiarity with the following areas will also be beneficial:

• Basic Python programming
• Tabular data
• Data analysis
• Fundamental database concepts
• Basic SQL querying concepts

By the end of the course, participants will understand:

• The fundamentals of Data Science
• The role of a Data Scientist
• Different data models
• The differences between SQL and NoSQL
• What a NoSQL database is
• Major categories of NoSQL databases
• The role of Hadoop within Big Data
• The fundamentals of Spark
• Graph database concepts
• Document-oriented databases

Participants will also be able to:

• Use common Data Science terminology with greater confidence
• Work with Python's native data structures and storage approaches
• Query NoSQL databases through Python APIs
• Perform foundational Big Data processing using Hadoop
• Analyse large datasets using Spark
• Evaluate technology options for different data problems
• Approach analytics problems from a Data Science perspective
