Data Storage and Preparation

FIT-UPAAcad. year: 2020/2021

The course focuses on modern database systems as typical data sources for knowledge discovery and further on the preparation of data for knowledge discovery. Discussed are extended relational (object-relational, with support for working with XML and JSON documents), spatial, and NoSQL database systems. The corresponding database model, the way of working with data and some methods of indexing are explained. In the context of the knowledge discovery process, attention is paid to the descriptive characteristics of data and visualization techniques used to data understanding. In addition, approaches to solving typical data pre-processing tasks for knowledge discovery, such as data cleaning, integration, transformation, reduction, etc. are explained. Approaches to information extraction from the web are also presented and several real case studies are presented. As a part of the course, students solve a project focused on ...

Learning outcomes of the course unit

Students will be able to store and manipulate data in suitable database systems, to explore data and prepare data for modelling within knowledge discovery process.

  • Student is better able to work with data in various situations.
  • Student improves in solving small projects in a small team.

Prerequisites

  • Fundamentals of relational databases and SQL.
  • Object-oriented paradigm.
  • Fundamentals of XML.
  • Fundaments of computational geometry.
  • Fundaments of statistics and probability.

Co-requisites

Planned learning activities and teaching methods

Not applicable.

Assesment methods and criteria linked to learning outcomes

  • Mid-term exam, for which there is only one schedule and, thus, there is no possibility to have another trial.
  • One project should be solved and delivered in a given date during a term.

Exam prerequisites:
At the end of a term, a student should have at least 50% of points that he or she could obtain during the term; that means at least 20 points out of 40.
Plagiarism and not allowed cooperation will cause that involved students are not classified and disciplinary action can be initiated.

Aims

The aim of the course is to explain the historical development of database technologies, motivation of knowledge discovery from data and basic steps of knowledge discovery process, to explain essence, properties and the use of extended relational and NoSQL databases as data sources for knowledge discovery and to explain approaches and methods used for data understanding and data pre-processing for knowledge discovery.

Specification of controlled education, way of implementation and compensation for absences

  • Mid-term written exam, there is no resit, excused absences are solved by the guarantor.
  • The formulation of the data mining task in the prescribed term, excused absences are solved by the assistent.
  • The presentation of the project results in the prescribed term, excused absences are solved by the assistent.
  • Final exam, The minimal number of points which can be obtained from the final exam is 20. Otherwise, no points will be assigned to the student. excused absences are solved by the guarantor.
