That depends on what kind of database you used for your application. There are 2 kinds of database here I want to notice:

1. File-based database, this is very easy to update, just copy and paste to the correct location, examples of these are Access database file (*.mdb), SQLite (*.sdb or any, the extension is not restricted), SQL Server CE (*.sdf),...

2. Service-based database, this is a little trickier, you have to remove the old database, attach the new one to the server, or using restore function (if the updated database file is a backup), or if your application supports connecting to multi databases, just create a new connection to attach the updated database. Examples of these are MS SQL Server (*.mdf and the log file with *.ldf), MySQL, Oracle, ...

I suppose your updated database has the same structure to the old one. (it means the update inludes only new data, not involving new structure).
