Question

I have a server application written in C#.

As the application running, there will be tens of thousands of key->value mapping generated, and this info needs to be persisted. For each of these mapping records, there will be update/delete operation.

What is the best approach to store it? No database.

Is there any performance issue with ConfigurationManager in such case?

How about for thousands of records? Is it possible to avoid using any database?

Thanks!

Assuming the fact you’re required to have no database by your hosting, there are still several options:

1. SQL Server Compact approach when you just place your DB files under App_Data and use ADONET to get to those as if it was a fully functional SQL server.
2. OLEDB connection to csv, dbf or any other structured file.
3. Homegrown solution – something like an IDictionary<> collection persisted manually into an XML, flat file, binary array or whatever else.
