The other tools are similarly priced. This package supports a single user and limits the size of the database. An ODBC driver is also available for the private edition. If you are interested in Yard, the private edition is an excellent way to become familiar with it. Documentation Documentation comes in the form of HTML files.
Documentation is available in German and English.
My only complaint is that the HTML version tends to put each sub-section into its own file, making it difficult to print a copy to read while you're away from your computer. The documentation assumes that you know SQL and are thoroughly familiar with Linux. Again, Yard is not a package for beginners. Installation Installation of Yard is driven by a shell script and runs smoothly. The script requests a location for installing the binaries, requests license numbers and keys, then copies the bits appropriately.
