The internet-accessible multi-user system of geodynamic monitoring data processing is presented. It is realized in the Java programming language as an interactive Web page which can be placed either on its own server of the awarding authority (Carpathian Branch of Subbotin name Institute of Geophysics of NAS of Ukraine) or on public Internet servers. Functionally the programs` complex consists of the following modules: module of receiving of geophysical information, database module, client modules, system administrator module.
The prototype of developed geophysical Internet portal as subsystem of software of geodynamic monitoring data acquisition and processing is presented. The prototype is based on database management system MySQL and it can be placed both on their own servers of an awarding authority (in this case – the Carpathian Branch of Subbotin name Institute of Geophysics of NAS of Ukraine) and on public Internet servers. Interaction of database and client modules within the bounds of this software is described.
