Data-binding a single application in different servers

Hi

I have created a Dataset (Dataset1.xsd) and bind data with a data-grid and its working fine.

In the connection string, the Data Source name is my development system's name (SQL Server database is in this system).

This application have to install in multiple locations (with local databases for each locations) with database replication. 

Please help, how to manage the data source name while installing in different locations. Should we use 4 different Exe files for each locations or is there a way to change data source of dataset without changing the source code.

Thanks
