Using web service from about 100000 users in the same time -


i have web service called about...let 100000 users in same time (within 3 hours). services reads , updates sql database using entity framework 4.1. here code

    [webmethod] public bool addvotes(string username,string password,int votes) {     bool success= false;      if (membership.validateuser(username, password) == true)     {         dbcontext context = new dbcontext();         appusers user = context.appusers.where(x => x.username.equals(username)).firstordefault();         if (user != null)         {             user.votat += votes;             context.savechanges();             success = true;         }     }     return success; }

the web service called android mobiles(as said maybe 100000 maybe more maybe less that`s not important right now). there deadlock possibility or possibility things go wrong?

what happen when reading database , when updating. 1 of answers said: updating field vote per each user. if there problem how advice me correct it.

thank in advance :)

this should fine.

the reason far can tell, thing happens when method called on behalf of user vote count (votat) in row in database increased. long touching own row, , not row might touched 1 of 99999 other users, there no contention between users, , should scale well.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
