Abstract
The article compares diversity indices applicability used in ecology to assess data types distribution for physical database schemes. The following dominance measures are used to assess the data type's diversity in the physical database scheme: Simpson's diversity index, Shannon diversity index, Simpson's evenness index, Pielu evenness index. A comparative analysis of the data type's diversity indicators for physical database schemes showed that the values of some indices obey certain rules. It is proposed to use diversity indices for physical database schemes' qualitative assessment. The indices considered in this work can also be used to build new models for assessing database complexity.
