Grum is a Grails based webapplication that provides storing personal user information (like address, email or phone) in a mysql database (if you change the jdbc driver and database connection data, you can use it which all databases that plays with hibernate). Users can be grouped.
Grum is an example how GORM (Grails' object relational mapping) Associations (1:1, 1:n, n:m) work. You can use it in your own grails applications, to manage user data. Grum is developed without any Grails Plugins, to minimize the dependencies.
Grum is not a product. It can contains bugs. You use it with your own risk. You have to accept the licence agreements of grails and the mysql jdbc driver.
And now build with Grails 2.0.
