Plugin with data access (multiple tables)

with the help of this link (https://www.nopcommerce.com/docs/75/plugin-with-data-access.aspx) we created a table within plugin.. but when i try to create another table in same class i got negative result... Is there any other way to do this possible..? i want to change the following code,

namespace Nop.Plugin.Other.ProductViewTracker.Data
{
    public class TrackingRecordMap : EntityTypeConfiguration<TrackingRecord>
    {
        public TrackingRecordMap()
        {
            ToTable("ProductViewTracking");

            //Map the primary key
            HasKey(m => m.Id);
            //Map the additional properties
            Property(m => m.ProductId);
            //Avoiding truncation/failure
            //so we set the same max length used in the product tame
            Property(m => m.ProductName).HasMaxLength(400);
            Property(m => m.IpAddress);
            Property(m => m.CustomerId);
            Property(m => m.IsRegistered);
        }
    }
}

thanks in advance.
