Data Replication with SQL Server 2012

Replication is the process of copying and maintaining database objects in multiple databases that make up a distributed database system. Changes applied at one site are captured and stored locally before being forwarded and applied at each of the remote locations. Replication provides user with fast, local access to shared data, and protects availability of applications because alternate data access options exist. Even if one site becomes unavailable, users can continue to query or even update the remaining locations.

In SQL Server 2012 Management Studio you can create replication very simply. Replication makes your database more secure and effective

Here the steps ,
1.  Log on to the database server and R-click on the Replication folder and select new publication
 

2. In new publication click next.
3. Select distributor  that can be responsible for storing replication info. I don't have any other servers I select default server in my desktop

4. In SQL Server Agent  select whether SQL Server agent should start automatically or not  then click next

5. Then it will displays snapshot folder.

6. Then select database that you want to replicate. After that it prompt select Publication type to replicate your database.  For each publication type preview window in bottom will show discription about each of them. Select it as you want and click next.

7. Then in Articles we can choose objects to publish in replication. then click next

8. Add data filters if you need. then click next in the prompt
9. Schedule snapshot agent as you want. It will give you time bounded option as well.
10. In Agent security add snapshot agent. I choose SQL Server agent account and finally click finish. and add publication name in prompt.

Its done..

Consume Service References Using Windows Strore Apps

Please note that this is not database related post. I'm recently working on windows store app development. In one scenario I have been pushed to consume .asmx web services. At that time there were no other resources to follow for me. I found this methods using some unorthodox way. In last few days several of individuals ask about consuming web services in Store apps specially .asmx.

Here we go,

1. Add service reference to the project. (Service1)

2. Create   Service1SoapClient object for consume service

3.  Assume that your imported Service1 contains method that returns string and method is GetServiceData(). Therefore you need to create object called GetServiceDataResponse nameOfResult  

nameOfResult variable gets response asynchronously  from web service

 4.  Then you can get the response body (actual response we need) fro called nameOfResul like this.

 



5. Then you can use this string as you wish. This string is the actual string that return by GetServiceData()

Enjoy..... :)
