For example, assume you have a mapping project with class CustomerInfoDataAccess for accessing Customer information from the database.

//Instantiate your data access class
private CustomerInfoDataAccess customerInfoAccess = new CustomerInfoDataAccess();
//Call the method to expose the data of interest
System.Collections.Generics.IList<CustomerDetail> customerDetails = customerInfoAccess.GetCustomerDetails();      
//You now have a collection of model objects that have been injected with data from the database!                     

For example, assume you have a mapping project with class ReportingDataAccess for accessing information for reports from the database.

        return rs.ToArray();
    }
    
    [WebMethod]
    public List<ProductModel> GetProductInfo(decimal productId)
    {
        return (List<ProductModel>)dataAccessManager.GetProductInfo(productId);
