I was looking for a tool to generate the schema diagram from my SQL Server 2005 development database. After some research I found the open source tool SchemaSpy which meet my needs, it also had decent reviews in few blogs. But I had problem running the tool to generate the Html documents for my schema.
After playing around with the option parameters, I was finally able to get it to generate the documentation needed. Couple of things to ensure before running schemaspy to generate documentation for SQL Server 2005 schema.
Make sure the Graphviz installation is added to your system PATH variable. Run the following command
java -jar schemaSpy.jar -t mssql05 -db <name of the database> -host <Ip address/hostname> -s dbo -port 1433 -u <username of the database> -p <Password for the userId> -o library
