I have created a desktop application whose database is on web server. But the application getting slow as the opening form have some fetching queries. That is why the application goes slow on deleting, saving, fetching and hence lost the flavour of desktop application.
So is there any way so that I can use a local mdf or sdf type database for any operation like delete,fetch,and insert etc. that effect on server database(in background) just like synchronisation. Please give me a demonstration and Example source code.
Sir I am not familiar with synchronisation. Can you Please help me. Thank you in advance

How these queries are constructed? Do you use SELECT * FROM TableName?

Please, read this: Ten Common SQL Programming Mistakes[^] before you make a decision to use local database.

I'm almost sure that the main problem is in query performance[^]. There is few ways to increase query execution time[^].

On the other side, it could be the lan-wan connection problem. You need to diagnose it.

Finally...
Syncronization between two databases is possible via linked server[^].
