Create new data source provider

In case you need to support other databases, you'll have to implement your own data source provider logic. You should implement IRulesDataSource interface and use it on rules engine builder.

public interface IRulesDataSource
{
    Task AddRuleAsync(Rule rule);

    Task<IEnumerable<Rule>> GetRulesAsync(string ruleset, DateTime dateBegin, DateTime dateEnd);

    Task<IEnumerable<Rule>> GetRulesByAsync(RulesFilterArgs rulesFilterArgs);

    Task UpdateRuleAsync(Rule rule);
}

You'll have to map each condition type defined by you to a data type on your rules data source. The ones available are:

• Integer
• Decimal
• String
• Boolean

For your guidance, check Mongo DB implementation: MongoDbProviderRulesDataSource.cs
