IST-4-DBM1 - ECTS 3.0

Abstract Part 1: Databases

This course introduces the most important concepts concerning the design and the use of databases. It covers the main issues in data modeling when considering the relational data model (structure, languages like relational algebra and relational calculus) and the key features of attribute-oriented models with respect to constructor-oriented models (like, for instance, Extended Entity-Relationship models). The fundamental concepts like the constraints and the normal forms will be explained and their impact on the quality of designed databases will be discussed. Finally, practical aspects of relational database design and use will be discussed. It includes a presentation of the SQL query language but also a short introduction to data warehousing and On Line Analytical Processing queries (OLAP). To be concrete, the students will have to understand the design of a real relational database and to practice database querying with a professional DataBase Management System (DBMS).

Schedule

The course exam consists into

• 1h test including 10 questions and 3 exercises (ER Modelling, Relational Algebra, SQL)
  • [[../../DBDM/Exam Group A]]
  • [[../../DBDM/Exam Group B 2022]]
• a small project to perform in pairs . Each project should have a presentation and 2-5 pages project report (mandatory) and a presentation.

Final grade is the weighted average between exam (0.4) and project (0.6)

Pre Lab Installations (Courtesy of Mohamed Ragab)

Lab Repository

1. Install PostgreSQL
   1. On Docker ``
   2. on Windows
      • Download and Install PostgreSQL for all platforms
      • Follow this tutorial for more details (Windows installation).
   3. on linux
      • Follow this tutorial
2. Install the psycopg2 Python Package to connecto to PostgreSQL
   • use th command

     1	pip install psycopg2

     in your command line.
3. Accessing PostgreSQL from Command Line:
   • Add the PostgreSQL installation \/home\ and \/bin\ directories to the enviroment variables.
   • use the command

     1	psql -U postgres postgres

     to connect to the the by-default created database \postgres\ with the user \postgres.
   • Enter your set \postgres\ password (i.e password of the default password that you have been asked at the time of installtion).
4. Connect To a PostgreSQL Database Server
   • show you how to connect to the PostgreSQL using psql tool and pgAdmin 4 GUI tool.

Part 2: Data Mining

Abstract

This course introduces the basics notions of datamining. It surveys techniques for data preprocessing, i.e., cleansing, integration, data reduction. Then, it jumps into foundational aspects of data mining like: Frequent Patterns mining, classification, clustering, outliers detection. The course examination consists of both a project and an exam with open and multiple choice questions and exercises.

Project Checklist

##

-REGISTER YOUR GROUP

• Identify the domain of choice, e.g., dataset presented above
  • YOU DO NOT HAVE TO PICK ONLY ONE DATASET
  • BUT BE CAREFUL BECAUSE YOU MIGHT HAVE TO CLEAN MORE THAN ONE
  • YOU CAN SUBMIT THE TAKS FOR APPROVAL
• you can pick out of problems (preprocessing + 2)
  • cleansing/preprocessing (mandatory)
  • frequent pattern mining
  • classification
  • clustering
• Explain why why you’re happy with the results.
  • evaluate the associations rules
  • evaluate the classification
  • evaluate the clustering proceedure
• present a notebook with comments and discussion of your result (github)
