Abstract: In Romania, the Black Sea seaside is one of the most popular places for the summer holidays. In this paper we propose a database model including information about the rates of holidays. This information refers to resorts, hotels, hotel star classifications, hotel room types, room amenities, hotel facilities, the holiday time period, the day number of holiday, dinning types, rates for accommodation, etc. We built this database model based on data presented in travel agencies' catalogues or websites.
We present some algorithms which can be used to explore the data. Our study is focused on detecting the best rates (depending on the tourist preferences) for the summer holiday according to some other features. In order to illustrate the applicability of these algorithms to the real data, we use the information provided by some travel agencies' catalogues and we present the most interesting results of our study.
Such a study can help tourists in making a good decision for their holiday and can also help hotel managers and travel agencies to develop their business.
This kind of tourism is a particular type of tourism, different from other Romanian ones, however our algorithms can be adapted for different other tourism types or for the case of sea tourism from other countries.
