The Diygeia Programme (Law 3861/2010, as amended and applicable) aims to achieve the maximum possible publicity of government policy and administrative activity, to ensure transparency and to consolidate responsibility and accountability on the part of public authorities.The Di@geia system has been in continuous and continuous operation since October 2010, satisfying the citizens’ need for transparency in public life every day. It serves about 5,000 operators, while on average around 2 million searches are carried out by 190,000 thousand single users on a weekly basis. To date, some 40 million documents have been posted, occupying approximately 20 TeraByte space in the system’s infrastructure. The average of the suspensions ranges from 15.000 to 30.000 per day.The aim of the project is to fully upgrade the existing application, with the main aim of expanding its functionality, enhancing the characteristics of transparency, usability, updating and dissemination of information. This reinforces the role of the system within a wider ecosystem of computer systems that support the efforts of the State for a modern administration. The implementation of the project will enrich the applications of the system and give it added value, enhancing the openness of the data and the participatory and personalised information of citizens and businesses.
