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 are 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.
