#CONSTRUCT System Rooms {group[user] <-> message <-> group[user]}

The overview of all chat avaible including all the configuration of them.

A sending unit that can contain a lot of type of media : text mainly, but also images , sound, link and other...

An logged entity that have personnal informations.

A list regrouping, friend list, nearby users, recently seen user, for each users

The interface that allow users/group to communicate with each other.

A very basic security system.

#THEORETICAL ARCHITECTURES - Main{ class Authentification {} class BackPanel {} class User {} class Group {} class Controller {} class Database {} class sChat {} class Tools {} }

###FUNCTIONNAL ARCHITECTURES Authentification.class.php{ description : "first level class of authentification process", functions : [ ], class-parents : "", } BackPanel.class.php{ description : "back office, mainly created to retreive data", functions : [ ], class-parents : "", } User.class.php{ description: "first level class of user process", functions : [ ], class-parents : "", } Group.class.php{ description: "first level class of group management", functions : [ ], class-parents : "", } Controller.class.php{ description : "call of functionnal class or functions, creating the root of the application", functions : [ ], class-parents : "", } Database.class.php{ description: "all database related queries", functions : [ ], class-parents : "", } sChat.class.php{ description: "first level of application, will call all simplified function of the project", functions : [ 'Controller', 'view', 'model', 'Authentification', 'user management', 'group managnement', 'chatRooms' ], class-parents : "" } Tools.class.php{ description : "Bunch of tools function called statically in needed situation", functions : [ ], class-parents : "", }

#TODOLIST/IMPROVEMENTS

• User

• Group

• Message

• Session

• Md5 password

• Authentification process (multi user connection)

• Define id_user_currently_connected

• Security Process of $this->current_id_user_connected (all function related to it)

• Friend list improvement (add friend with email, nickname, etc)

• Class Based structure (problem appeared in Database class where it was too messy to understand the functionnal rôle of Database, dividing it will help improve it)

#RANDOM ALGO && SELFASKS User doesn't exists -> register -> user exists

When init dB ? user && group making || rooms && chat && messages

Db problem : all functions are dependant to $pdo_object, to call them externally to the Class, how you we do, without having the arguments ?

class Db{
	/*
	* Problem 
	*/
	function __construct()
	{
		$datArg = necessarySuff();
		randomDbFunction($datArg);	
	}
	function randomDbFunction(randomArgDependant)
	{
		//randomCodeWithArgDependant
	}
	/*
	* Solution 1
	* Proceed the same way for each functions
	* Negative factor : performance loss
	* Positive factor : general isolation
	*/
	function callToRandomFunctions()
	{
		$datArg = necessarySuff();
		randomDbFunction($datArg);	
	}
	/*
	* Solution 2
	* Negative factor : not sure if it's stable (depending on context)
	* Positive factor : general isolation plus functionnal programming respectfull
	*/
	private datArg;
	function __construct()
	{
		$this->datArg = necessarySuff();
		$this->callToRandomFunction();
	}
	function callToRandomFunction()
	{
		randomDbFunction($this->datArg);
	}
	function randomDbFunction($this->datArg)
	{
		//randomCodeWithArgDependant
	}
}
