RESEARCH OF THE CLIENT-SERVER APPLICATION «GUIDE TRAVELER»

The study considers analogs of the developed application, a model has been developed that has features — the sections of positions and transitions are introduced for the interaction of the application with the Google service, provides the user with the opportunity to immediately receive a reference map without using other software, and saves the internal memory of the device. The constructed model was used when designing a client-server system providing a reference map. The principles of the structural organization of client-server systems were also considered. The architecture of the system is designed, its client and server parts, in the form of UML diagrams, the structure of storing user data and data about search objects is determined. The constructed Petri net with a graph of reachable markings, the analysis and modeling of the net is performed. Also, based on the graph of algorithms schemes, the algorithms necessary for the implementation of the tasks were developed. A system has been developed that implements the application of the map reference book, which can be introduced in the tourism industry for use by travel agencies.
