Question

What it best location to store various configuration settings of a web site modules.

Creating class (that inherit ConfigurationSection) that map the settings in web.config file?
Or creating some DAL and BLL clases that work with database?

Answer 1

I’ve used a simple heuristic to categorize each configuration variable into one of four categories:

1. Compile time configuration (changes done together with code changes) – if possible then inside the code or assembly (as an embedded resource), otherwise in web.config
2. Server instance specific configuration (SQL connection strings, local file paths) – in web.config
3. Application (database) configuration (feature selection and other global application settings that change rarely, if ever) – in database but without an UI
4. Application configuration – in database, accessible through an admin UI
