C# databases, as a term, can be misleading. A database management system (DBMS) that works with C# could be either a relational DBMS (RDBMS), an object-relational DBMS (ORDBMS), or an object DBMS (ODBMS). C# also works with object-relational mapping products. Information on each of these technologies can be found on this site.
If you want to use a tool that makes the mapping of C# objects to RDBMSs easier, consider object-relational mapping products. Object-relational mapping products integrate C# language capabilities with RDBMSs. Database objects appear as programming language objects in C#. Often, the interface for object-relational mapping products is the same as the interface for ODBMSs. Using an object-relational mapping product means you will have less code to write and, depending on how you use your data, you might have higher performance over an embedded SQL or a call interface such as ODBC or JDBC. See caching for object-relational mapping.
If you are interested in storing C# objects directly, consider ODBMSs for C# databases. ODBMSs use the same object model as C# and allows C# objects to be stored directly with no mapping.
Both techniques use transparent persistence. With transparent persistence, the manipulation and traversal of persistent objects is performed directly by C# in the same manner as in-memory, non-persistent objects.
