Hi,
Can someone tell me in term of performance and flexibility which approach is better:
 Using multiple web services within an application, each web service contains only 1 web method VS using a single Web Service with multiple web methods..(each web method will retrieve data from  the database and populate the Web form). 
I want to know if it is better to transform each web method to web service or to regroup all web methods in only one Web Service.

Thanks in advance.

Use one WebService.



For each Web Service you'll need a WebReference in VS.

1 WebService = 1 WebReference

5 WebServices = 5 WebReferences



What you'll gain is flexibility when you move the WS's to a different server or change the virtual directory.



And when you tell a client/customer that for each WebMethod they want to call they'll need to create a seprate WebReference.



Oh, and security and code reuse.  



If you still want to multi-WebServices then you should group them by Business Components.



Just my 2cents.

Thank you very much for your reply.. It will be hepfull for me..

my business component has different classes depending on the functionality that i have for example i have class called Group and another one called Addresses. my project idea will be addresses that have contact details ....... what i was thinking to have is one web service project that have many web service files like Group and Addresses which is similar format to the Business component ... is that a good design or it is better to have only one file in the class that contains all methods!!!! just i want to ensure i am approaching the best design as i am not expert in WS
