|
The WARMIS Database is a relative database, consisting of tables with text data. The database contains information on water and land resources and use, climate, economic indicators, and water quality. In compliance with the data source, data can be divided into the following levels: primary, secondary and tertiary. Data can be grouped by features of object they belong to.
The main spatial unit of the WARMIS database is a planning zone. Thus, various tables of the database can be tied together through this common unit. The main time unit is month. Within the WARMIS, the following information levels are differentiated: 1. Primary data; factual field measurement data or data, obtained by calculations using field measurement data through simple arithmetic operations (addition, subtraction, multiplication, division). 2. Secondary data; factual data, based on primary data, but calculated by using certain algorithm (complex mathematical operations, models of balances), or calculated by using primary data updating and without it, including calculations of missing primary data. 3. Tertiary data; data, obtained as a result of incorporating primary and secondary data by expert (calculations, strategies, scenarios), which do not necessarily reflect the current situation. Empirical reference data available in WARMIS database can be referred to primary data, because they are used for directly putting into the WARMIS. However, in itself such information is usually based on primary and secondary data of other databases. In order to denote difference, empirical data can be classified as the forth category of data. Attention should be paid to that at present WARMIS database contains mainly primary data in the partial presence of secondary data in diverse places that is a result of data verification procedure.
