Basic concepts : project, task, group, event

1 - Project

A project is characterized by:

• a project name,
• a start date of project,
• a list of tasks, groups and events,

To follow the realization of the project, it may also be defined a fixed start date and a fixed end date (when the start was set).

Also other information fields can be filled: Workload, Content, Responsible, Advancement percentage, Inputs, Outputs, Comments ..

• a group name,
• the option essential or ancillary,
• the tasks and events member of group,

It is also possible to fill the same information fields as for tasks. Other data are computed from project data.

4 - Event
