Abstract

This diploma thesis is concentrating on topic of Czech publicly available data, especially economic. Firstly it makes survey of current situation, walks through more and also less known sources and compiles them into an overview. It focuses more on database of Czech Business Register (Register of Economic Subjects - RES), describing its attributes and methods of data preparations to form suitable for analyses in database environment PostgreSQL. One of these methods is also new concept of algorithm for geocoding, where are spatial coordinates assigned to elements via comparing of address with database RÚIAN.

Analytical part is divided into three case studies. In first one, there is use of advantage of long time range of database RES in examining of evolution of economic environment in the Czech Republic, from 1990 to present. The most common way to do that is by visualising cumulative totals of active business entities. There is also made survival analysis of these data. In second case study, there are regions of Czech Republic described by concentration of different target groups of business entities. The concentration is calculated for municipalities in relation with number of inhabitants and there is evaluated both current and past states, also with a difference between them. In the last case study is performed multidimensional clustering to create a new spatial division of the Czech Republic in terms of economic activities.
