Lino applications are basically normal Django applications, but instead of writing Admin classes for your Django models, you write Tables.

A Table describes a set of tabular data independently of user interface and medium (paper, screen, interactive or not), but with all the meta-data information necessary for any front end to produce a satisfying result on any medium. This is the theory.

Your tables are subclasses of dd.Table, and they must be defined in your application's 'models' module because Lino 'discovers' and instantiates them automatically at startup.

A Layout describes an entry form in a GUI-independent way. Users see them as Tabs of a Detail window (whose main component is a FormPanel)

Instead of having each application register its models to the admin site, you write a main menu for your site that uses your Reports. This is is currently done in a file, usually in the same directory as Django's This approach is less pluggable than Admin-based applications, but enterprise solutions don't need to be plug and play.
