h2. The Admiral

The application entry point is the [[Thesaurus#Admiral|Admiral]]. It simply lists the [[Thesaurus#Module|modules]], and the selection of a module displays the list of [[Thesaurus#Feature|features]] related to that module. Kind of menu and sub-menu.

You can find [[Modules|here]] the exhaustive list of modules in [[Thesaurus#digest|digset]].

h2. The Search screen

Usually, a feature is accessible through a Search screen. The search screen allows to specify criterias and fill a list of matching [[Thesaurus#Entity|entities]].

The typical Search screen has next to the criterias the following control buttons :

* a Search button that fills the grid according to the criterias

* a Clear button to reset the criterias

* a Close button to close the screen. 

It also has next to the grid the following control buttons :

* an Add button to create a new entity

* an Edit button to modifiy selected entity

* a Duplicate button to create a new entity pre-filled with selected one

* an Export button to generate a spreadsheet in cvs format

h2. The Input screen

The creation or modification of an entity is done through an Input screen.

The Input screen can be called in three _modes_ :

* Read : an existing entity is shown in read only

* Edition : an exisiting is shown and can be modified.

* Creation : a new entity will be created

The typical Input screen has the following control buttons :

* Delete : deletes the selected entity (only in Creation mode)

* Save : records the changes in Edition mode, creates the new entity in Creation mode.

* Cancel : does nothing

The Input screen can have two _input types_ :

* Impatient : the screen opens in Edit mode

* Intuitive : the screen opens in Read mode and there are buttons to switch to Edition mode.

Furthermore, the Input screen has four _behaviours_, when a control button is pressed :

* Go to Read mode : the screen switches to Read mode, showing the selected entity

* Go to Creation mode : the screen switches to Insert mode, ready to add another entity

* Stay in Edition mode : the screen doesn't switch mode

* Closes : the screen is closed

Some mixes of _mode_/_input type_/_behaviour_ are obviously not possible. As the Impatient behaviour never switches to Read mode, there is no Go-to-Read-mode _behaviour_. 

The Search screen calls the Input screen in Creation mode when the button Add or the button Duplicate is pressed, in Edition or Read mode when the button Edit is pressed.

Usually the screens with complex information are opened in Intuitive _input type_. It is possible in such screens that some actions have to be done after the entity is saved.
