ARAD is a public database forming part of the Czech National Bank's information service. The purpose of the database is to create a unified system for presenting time series of aggregated statistical data from various internal and external CNB sources. The data are stored in the database by subject area (in "data tables"). Data are located in the data sources according to where those data are acquired. The database is updated periodically using data from more than 100 data tables. Its outputs are broken down into the following basic areas using a retrieval program.
These basic areas are then branched hierarchically.

The application has a retrieval menu allowing the user to navigate easily through the database's hierarchical structure to the required indicator. The indicators are aggregated economic variables defined by a combination of data from the data source.
The user uses a list of predefined arrays of indicators for each subject group. These are selected by name, so no knowledge of the source table structure is required.
The program calculates the time series for the selected group of indicators (array) and displays them in the chosen format (HTML, TXT, Excel). The user has the option of limiting the amount of data by altering the time interval, which is set as wide as possible by default, or by reducing the number of predefined indicators in the array. Each array contains a predefined list of indicators. Users can modify this list to their individual requirements by clicking on the relevant check box to exclude an indicator from the list. To exclude indicators more quickly, click on Delete (or in the opposite case Select).
The following items appear on the Methodology tab in the screen for entering final query arguments in the database:
Attention! We recommend limiting the interval selected when using the Lock Date Column function in order to prevent an erroneous response from the application.
