design - Representing parameters/configurations/settings -


OK, we say that I am writing an application using an object-oriented language, and I have Key-pairs pairs that represent program parameters / configurations / options / settings / etc. These may be the initial value of some variables, or only those values ​​which are not obliged to change the addition of sessions In my data model these I value the price I can represent?

My initial idea is to store all the values ​​in only one class that can be reached globally (possibly singleton) because these values ​​will be used in different places of the code. However, it will depend on this singleton to the other singles.

Is there a problem in this situation? Is there another ideal solution I have not thought of? How do you usually represent this kind of data? Should I be aware of anything related to this problem?

Thanks

You would like to use dependency injection An interface IConfigurationProvider Create . Create a class DefaultConfigurationProvider , which implements the interface and performs the actual function. Creates another object that relies on config data, expects an IConfigurationProvider example and provides an example of DefaultConfigurationProvider . The most dependent injection framework will handle it for you.
