Data on product categories and hierarchical relationships among them are presented in a built relational database. Fresh fruits category, including 14 product types (cherries and morellos, apples, peaches and apricots, grapes, etc.) is the subject of consideration in this work. The article presents mathematical models describing the dynamics in average prices and purchased quantities of fresh fruits, average per household in Bulgaria. The examined period covers generally 17 years from 2001 to 2017. Linear and quadratic equations have been constructed and analyzed. The results show a growth in purchased quantities, average per household for almost all studied fresh fruits. A similar situation occurs with the other examined indicator. An increase in the average prices of the 14 fruit types has also been observed for the surveyed period, while for some of them (grapes, plums, pears, cherries and morellos, strawberries and raspberries), compared with the rest, this process has been more intensive.
