Course details

Data Storage and Preparation

UPA Acad. year 2023/2024 Winter semester 5 credits

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.

Learning objectives

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.

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.

Why is the course taught

The aim of this course is to demonstrate how to work with complex data around us, how to store such data, how to get oriented in such data, obtain useful descriptive characteristics from such data, and how to prepare such data for extraction of hidden information/knowledge by application of machine learning methods and other advanced analytical methods.

Syllabus of computer exercises

  1. Objects and documents in databases
  2. NoSQL databases
  3. Knowledge discovery from data - data preprocessing

Syllabus - others, projects and individual work of students

Creating an application for processing large structured and unstructured data, which includes, among other things, obtaining and retrieving data, preparing them for further use (e.g., knowledge discovery in databases) and creating descriptive characteristics for selected data.

Progress assessment

  • Mid-term written exam; there is no resit; excused absences are solved by the guarantor deputy.
  • The implementation and submission of the project results in the prescribed terms; excused absences are solved by the assistant.
  • Final exam with; 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 deputy.

Exam prerequisites

At the end of a term, a student should have at least 20 points out of 44.
Plagiarism and not allowed cooperation will cause that involved students are not classified and disciplinary action can be initiated.
