Public Database of the CZSO (VDB) is developed as a fundamental and unified data source for presentation of statistical data designed mainly for the public.

VDB contains solely aggregated statistical data covering all observed areas of statistics. It uses results of statistical data processing in the CZSO as well as statistical data from external and administrative sources especially from other work places of the state statistical service. It does not focus only on data covering the Czech Republic, but, in addition, it provides data for territorial administrative units of the CR (regions, districts, municipalities and cities, etc.) and also data from abroad.

VDB is linked to the statistical metainformation system. The data is identified by means of metainformation specifying the subject-matter, time and space dimension. Each data is equipped with information on data quality, confidentiality, source, contact person and wide range of other supplementary information.

Public Database secures confidentiality of presented data.

VDB is based on a single figure principle. The data may appear in a different context in different outputs (tables, maps, graphs, etc.).

VDB aims to provide an interactive user friendly access to statistical information including relevant metainformation, also to users with impaired vision and in multi-language regime.

VDB as well as other information systems in abroad is focused on different user groups (lay and professional public, internal and external users).

• interactive access to information for external users
• immediate provision of partial information
• export and print of displayed information
• preparation of more demanding (special) orders
• preparation of standard and non-standard e-publications, yearbooks, bulletins
• source of data for web site of the CZSO and other institutions (e.g. public administration portal)
• web services enabling on-line export of statistical data

VDB is created as a data mart drawing data from databases developed in the process of statistical data processing.

• primary level – containing mainly database of aggregated statistical data
• secondary level – containing statistical outputs (statistical tables, maps, graphs)
• interface – applications securing transformation and input of data to primary database (including universal XML interface) and applications enabling access to data and outputs

The core of VDB is a database with statistical indicators and their values. The structure of this database is closely linked to the metainformation system of the CZSO and mainly to the database of nomenclatures and classifications.
