Migration of batch processing of a raw goods system from COBOL to JAVA.
Project duration: 6 months
Brief description
The batch processing implemented in COBOL for the raw goods system is successively replaced by a modern Java-based individual solution with Spring Services. The aim here is to ensure high mutual compatibility with the existing COBOL programs. Stack processing is not interactive and runs in accordance with a timed schedule. Individual jobs can be started manually from the raw goods system if new calculations are necessary.
Subject description
The master and transaction data from the raw goods system is stored in an Oracle DB. This data is transferred in a weekly cycle from a normalized schema to a schema optimized for reporting. These batch jobs are implemented as a Spring Service that use the Java persistence API (JPA) and the Spring JDBC template to access data.
