Connecting two computers

[Mangotree]

I am developing web application of banking in asp.net. I store all the database in one system(acts as server), and application is runned in other system. So when any modifications are done in the records like withdrawals by running application, those updates has to be reflected in the database of other system.SO my question is how to connect those two systems?

Mention the IP or computername of the Server in Application's Webconfig file.

For Example ,you are using the Server 127.0.0.1 (Server IP).

In WebConfig File mention the Ip as DataSource while adding ConnectionString.

<connectionStrings>
    <add name="ConnectionString" connectionString="Data Source=127.0.0.1;Initial Catalog=databasename;Persist Security Info=True;User ID=sa;Password=admin@password123"
      providerName="System.Data.SqlClient" />
</connectionStrings>

Make sure that you take precautions to secure your connection strings.
You can encrypt the connection strings portion of the web.config file using tools available to you in IIS and ASP.NET.
