Prerequisites

Objectives
This course aims to introduce students to the acquisition, processing, storage, and retrieval of large scale data in support of data science tasks.

By the end of the course, the student should be able to
1. list the steps involved in a large-scale data science project and describe the functions of each;
2. know the data science toolkit;
3. understand the fundamental concepts of big data;
4. know how to apply methods for data acquisition using Python software packages, APIs, and web scraping;
5. master the process of storage and retrieval of large-scale data;
6. understand and know how to apply the appropriate strategies for large-scale data processing;
7. be familiar with the map-reduce paradigm;
8. know the fundamentals of the most relevant large-scale data processing frameworks;
9. know how to use, program, and process large-scale data using the Spark framework.

6. Large-Scale Data Processing Strategies
- How many data are many data?
- Strategies overview to handle large-scale datasets (compression, databases, chunking, scale-up (expand resources); scale-out (data parallelism) and big data).
- The importance of GPUs in the context of large-scale data science.

7. Programming Large-Scale Applications based on the Map-Reduce Paradigm

- Spark vs Hadoop Map-Reduce

Dask
- What is Dask?
- Characteristics
- Advantages
- Architecture
- Dask vs PySpark

9. Large-Scale Data Processing with Spark
- Introduction to Core Spark Concepts

Evaluation Methodology
Periodic Evaluation
- P1 - Project I (team work): 40%
- P2 - Project II (team work): 40%
- T - Test: 20%

The final classification of the course results from the weighted average of the classifications obtained in the defined evaluation components. The student obtains approval at the course, being exempt from the Exam, in case he/she obtains a grade equal to or greater than 9.5 values.

Final Assessment
- Exam: 100% (computer-based test with only partial access to the contents)

Admission to the Teaching/Learning and Exams:
- Minimum of 70% class attendance during the teaching-learning period (except student workers);
- Minimum score of 6 points in AE, where AE = ((P1 * 40%) + (P2 * 40%) + (T * 20%))

Failure to comply with any of these items (including the submission of any of the projects after the foreseen period) prevents the student from being approved.
