This is a fundamental course that covers basic concepts on algorithms, data structures and databases. Even if the objectives of the course are common, this course spans two different tracks: one for students who have a major in Computer Science and another track for the rest.
The methodology is different for both tracks. For the former, it is a project-oriented course focusing on dataOps / MLOps, while for the latter it covers basic material on algorithms, data structures and databases in a guided, yet autonomous learning manner that will allow them to develop complex data systems.

Computer Science for Data Science
Students in the minor track will put in practice all the contents of the course by solving exercises related to algorithms, data structures, and databases. Students in the major track will undertake a project spanning all main phases of a data science. As result, they are asked to develop a quality realistic end-to-end system architecture for a data science project. Objectius:39467510111213 Continguts:

Metodologia docent
The students are divided in two tracks: one for students with a minor in computer science (track 1) and another one for students with a major in computer science (track 2).
Students in track 1 will study fundamental concepts in algorithms, data structures and databases. First, additional material to read, study and understand is provided. Lectures focus on the main concepts and those that require some additional explanation to guarantee a proper understanding. Students will have a large bank of self-assessing exercises to practice their understanding on their own. During the course, they will have to solve some mandatory exercises to guarantee a smooth learning process. Additionally, in the face-to-face lectures, the lecturer will solve doubts, go through representative exercises to guarantee a solid understanding and discuss exercises (to be solved during the lecture) with the students.
Students in track 2 will carry out the DS-EtE project and, for them, this course is a project course. There, students must create an end-to-end system architecture to ingest, store, process, learn models and deploy such system for a realistic project with realistic data. The students must develop good practices developing such architecture (what nowadays is known as DataOps / MLOps).
This course has a strong self-learning component and shares the same objectives in both tracks. The lecturers will supervise the students progress during the semester to guarantee a proper progress.
Mètode d'avaluació
Let DBM = Databases midterm exam grade,
DBF = Databases final exam grade,
DBEx = Database exercises to be solved during the course,
ADSM = Algorithms and Data Structures midterm exam grade,
ADSF = Algorithms and Data Structures final exam grade and
ADSEx = Algorithms and Data Structures exercises to be solved during the course,
DS-EtE = DS-EtE project grade
Then,
1) If the student followed track 1 (see methodology) the mark is calculated as follows:
BD = MAX (0.2*DBEx + 0.8*DBM, DBF),
ADS = MAX (0.2*ADSEx + 0.4*ADSM + 0.4*ADSF, ADSF).
ADSDB (final course mark) = 0.5*BD + 0.5*ADS
2) If the student followed track 2 (see methodology) the mark is calculated as follows:
ADSDB (final course mark) = DS-EtE

This course assumes basic competences in algorithms, data structures and databases. The course is structured to cope with different backgrounds and learning needs but basic knowledge on Computer Science principles is assumed: notions of computer architecture, basic programming constructs and data structures.
