SysDB is a tool for synchronizing XML Files (based on XML Schema) and a Relational Database. XML files are stored and managed in a database. Data is managed in configuration: when you change a XML file, only this file will be added into the base. Old versions can be easily retrieved from the database. Database Schema is automatically deducted from the XML Schema. Database and XML Schema are synchronized automatically keeping the base management as simple as possible: there is no need to create a new base each time the Schema changes.
