== Use cases ==

* user logs in
* user/anonymous user views project
* user changes preferences
* user adds project
* user adds release
* user subscribes to project notifications

* pipeline manager views pipeline
* pipeline manager denies release/project
* pipeline manager accepts release/project

* user logs out

== Activities ==
All activities result from a corresponding use case. The following activities are not yet finalized.

=== activity: user logs in ===
* user sends login credentials
* backend checks credentials, in case of ok, continue, else bail out.
* backend shows user's personal page
** if user has projects, show button 'my projects' in infobox
** includes 'add project' in infobox
** if user is pipeline manager, show button 'my pipeline' in infobox
** if user has subscribed to projects, show section ''subscribed projects''

=== activity: user/anomyous user views project ===
* user/anonymous user selects project
* backend loads project description from live database
* backend formats project description
* backend shows project description
** if user is maintainer of project, show special functionality 'add release' button and 'update informations' button

=== activity: user adds project ===
* user wants to create a new project, web project creation page is displayed.
* user fills in informations
* server checks data and in case of error displays project creation page with error message, else continue
** server needs to check if the shortname is unique
* server stores informations in the temporary database and marks them as to be acknowledged
* server informs user about current status
* server sends notification to pipeline managers
* pipeline managers log in
* pipeline managers accept or reject project (see corresponding activity)

=== activity: user adds release ===

* user wants to add new release
* user must be within a project overview
* if user is maintainer of project, show possible 'add release' button
* user selects add new release
* backend shows new release overview page
* user fills in informations
* user sends form
* backend checks informations
** check for completeness
** check if there is no other release in the pipeline
* in case of errors, backend informs user, else continue
* backend adds release to temporary database with flag 'to be acknowledged' ( means, pipeline_status = 0)
* backend informs release managers
* backend shows informations on the process to user

=== activity: user subscribes to project notifications ===

* user wants to subscribe to project notifications
* user must be within a project overview and must not be subscribed already
* user clicks ''subscribe''
* server adds user to subscribers for this project
* server shows subscription ok

=== activity: pipeline manager views pipeline ===
* pipeline manager wants to view all release projects
* backend generates list with all to-be-released-projects based on flag in temporary database
* + backend generates list with all to-be-released releases based on flag in temporary database
* backend generates complete list on one oage.

Note: to be acknowledged projects or releases have flag pipeline_status set to 0.

=== activity: pipeline manager denies release/project ===

* pipeline manager views release or project informations
* pipeline manager clicks 'deny'
* in case of project, backend checks if the project exists in the final database already, if so, it restores the informations from the final database into the temporary database
* in case of release, backend checks if the release exists in the final database already, if so, it restores the informations from the final database into the temporary database
* backend sets comment in database
* backend informs maintaining user about denial
* backend shows pipeline overview

=== activity: pipeline manager accepts release/project ===

* pipeline manager views release informations
* pipeline manager accepts release
* backend stores pipeline manager id in the database for that release
* backend marks release in database as accepted
* backend generates release informations
* backend shows pipeline overview.

=== activity: user logs out ===

* backend kills session
* shows log out teaser ;-) [just a joke]

== Technicals ==

* There exist two duplicate databases, one for temporary / to-be-ack working and one for live working

=== Notifications ===

The hierarchical project tree allows subscriptions on various levels.

Example of an project tree:

/projects
/java
/projectA
/projectB
/projectC
/projects
/client
/projectA
/server
/projectB
/projectC

If at one level of this hierarchy an event is generated, all subscribers of higher tree nodes are automatically informed, too (see [[PubSub]]).
In this simple example a user may subscribe to any node in this hierarchy. If the user subscribes to /java, he is automatically informed whenever there was activity beneath java. If a user subscribes to projectA, he is only informed about activity for projectA. Of course there can be redundant subscriptions, for example a subscription for /java and /client. The notification system must be smart enough to filter out these redundancys.

=== Finalization ===

* When a project is finalizes or released, the system moves the entire dataset from the temporary database into the live database.
* When a project has to be restored from the current live system, i.e. due to denial of a task, the entire project's dataset is moved from the live system into the temporary database.

== Database design ==
As said, two similar databases exist:
* Database SOFTWARE_MAP_LIVE
* Database SOFTWARE_MAP_INTERMEDIATE

=== Conceptual Diagram ===
This conceptual data diagram is not yet final. It is work in progress.

=== Physical data structure ===
This physical data structure is not yet final. It is work in progress.

== References ==
The charts are created with ArgoUML and devaki-nextObjects.

== Further ideas and informations ==
* Need to add a 'link to us' button
* Season skinning
* Project rating
** Light bulbs as indicators
* Project comments
* Top viewed projects
* Top rated projects
* Project of the month
* Project of the year
* "Vote your favorite" Cup Contest
