SysDB is a tool for synchronizing XML Files (based on XML Schema) and a Relational Database. XML files are stored and managed in the database. When the XML file change, only changes are added on the Database and all versions can be retrieved from the database. The structure of the database is completely dependent of the XML Schema which describes the XML files. The database schema is automatically synchronized with the XML Schema, keeping the database management as simple as possible. When the XML Schema changes, there is no need to create another database. Database Tables and Column are updated to encompass new XML elements.

xmlArchitect, an intuitive xml schema editor, allows the xml developer to create schemas and show a visual representation of what the xml document should look like for that schema. xmlArchitect also allows the developer to edit this visual tree representation of the "mocked-up" instances document, which will dynamically update the schema for that document. Currently in an early beta (ver. 0.1.0.17), xmlArchitect is available for free download during this beta-testing period. It's constantly being updated, so visit the site frequently for newer versions.

The tool can also be run in batch mode to quality check multiple XML schemas in a single run.
