Database handling by mutipl host

I am using database in one server .I wanted to access that database from multiple location but is开发者_Go百科sue is that when one access that data in the table no body can access those data.What will be that better way to handle?

You should be giving more details about your problem

1. What RDMS do you use?
2. What is the transaction isolation level?
3. Are you performing any explicit table locking? If yes, what kind of locks are you acquiring?
4. Do you have synchronized methods in your app code?

It's rather hard to believe but it might be the case that your using serializable isolation level and that your transactions update the same table.
