Annual ongoing enhancements and support of the EEG internet portal

The transmission provider currently implements the EEG using a Java-based distributed application with the SAP WAS 6.40 as the application server and Oracle as the database. The data recorded using EEG Internet needs to be copied to this system for further processing. It is therefore necessary not only to create the Internet application, but also to expand the existing system. EEG Internet makes it possible to record and process the data that the transmission provider requires to implement the EEG (such as forecast transfer to the end consumers of the electricity supply companies supplying end consumers within its control area). This data is retrieved from the internal Oracle database to a MySQL database, only when requested and only for the duration of an Internet session. The necessary data transport is carried out by an EAI tool. EEG Internet is based on Java and accesses this MySQL only, via the the Hibernate persistence framework.
