How do I choose between WCF, REST, POX and RIA services for a new Silverlight application -

-

A silverlight application can add it to a lot in different ways' server <

  • (or it is still left?)
  • Pox - Plain old XML (e.g., original XML)

    • For each of these, please say what is for this and when you will not use it or not, I have a very large description of "rules of thumb" for selection between them. not I see In.

    (The problem is that when designing your first Silverlight app, you should know that it is time to know all those who do not.)

    My two Euro Euro:

    WCF The service can be seen as a business layer, when your service is "intelligent" like "CalculateDiscountForClient" .

    ADO. Net Data Services (In fact, only a permanent implementation) is appropriate when your application is basically data-centric and the service is only a front-end for the database. That is, all of your service methods are GetCustomers, CreateInvoice, etc.

    RIA Services is a very new technology I have not used yet, but it seems that the application is useful in making applications, including the Silverlight part and service too tightly. Together: You define your service classes and methods in the service project, and they are automatically replicated in the Silverlight project in design time. In addition, you can define both WCF-style "action" methods and ADO.NET data service-style "data" methods. Use Pox if the future of the client part is changed from the client's future to any other technology (for example HTML + AJAX), then use it. Most interoperable options

    Regarding the differences of WPF, only I can think that for data access, whenever possible I will directly use ADOnate Data Connection (properly embedded in Data Access Layer, LINQ From SQL or like) instead of ADO.NET data services, because it is a more flexible way I have to say anyway that I have never developed anything in WPF.

    MySql variables and php -

    I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

    url rewriting - How to implement the returnurl like SO in PHP? -

    -
    This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

    Which Python client library should I use for CouchdB? -

    -
    I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
