Lifetype is really cool! I am trying to install it for a portal as the blogging solution. Can I know if there is any documentation of the database structure - like what each field means?
It would be nice if we had such documentation, but unfortunately we don't have it... But table names and field names are pretty self-describing, you shouldn't have any problem.
But please note that you shouldn't access the database directly, and that the preferred way to interact with LT's data model is via the API. All data tables and objects have their own encapsulations, please have a look at the DAO module.
