Database modernization and optimization of the (test) data migration for EEG2.0 and EEG Internet

Project duration: 1 year, 9 months

Brief description

Due to the constantly growing amounts of data on the part of the customer, it is essential to develop the application along comparable amounts of data, if need be also to optimize algorithms in order not to exceed acceptable system response times. For this purpose, the customer provides data from productive operation, which, however, is first obfuscated. In addition, the aim is to upgrade the database server system. ETL scripts are provided as part of the project, whereby the transformation step consists of DSGVO-compliant obfuscation and omitting irrelevant fractions of of the data. Another part of the project is dedicated to the preparation and implementation of the database migration from Oracle Vs. 12c to Vs. 19c on the DB servers used by then development team.
