In 2004 the Ministry of Education of the Slovak Republic commissioned the EEA to explore possibilities of open source (OS) software usage in informatization in the Slovak Republic. Based on the information collected from 2.000 companies and institutions we identified basic types of information system (IS) architecture in public administration, education and in small and medium enterprises (SME). Within individual applications the features of commonly bought software (proprietary) and available OS solutions were compared. The solution makers subsequently designed conversion process for each application (migration plan) for suitable OS alternative. Survey conclusion:
- Open Source software can be successfully used in the IS of public administration, education and SME – and not only as full-value alternative to proprietary products, but also as elementary base of the whole system.
- Vaster usage of the OS would bring such remarkable savings and furthermore such important positive secondary consequences for whole society, that its usage in this scale would remarkably accelerate the whole informatisation process of the society. According to estimation in then effective prices the savings on 50 % migration during 8 years would reach up to € 600 million (SKK 18 billion). This amount does not reflect savings earned through creation of healthy competitive environment on the market.
