What is the difference between SqlCeConnection and SqlConnection C#?

I am using Eclipse with its database. I am using SqlCeConnection for connecting however, it doesn开发者_Go百科't seem to hold the data I don't know why. When I right click on the db and say "show table data", it shows inside null.

I saw SqlConnection. What is the difference between SqlCeConnection and SqlConnection? And do you have any idea why there is no table data in my database?

SqlConnection is for SQL Server Databases

SqlCeConnection is for the Compact Edition
