        public GroupsExample(SchoolContext dataContext)

        }

        public void Example()
        {
            // Instantiates datastore with datawindow: d_studentgrade_groupsort
            var datastore = new DataStore("d_studentgrade_groupsort", _context);

            datastore.Retrieve();

            // Gets the properties for the Groups keyword.
            var groupMetas = datastore.DwMeta.Groups;
            Console.WriteLine("Groups Count: {0}", groupMetas.Count);

            foreach (var item in groupMetas)
            {
                foreach (var byItem in item.By)
                {
                    Console.WriteLine("Level: {0}; By: {1}; Sort: {2}",
                        item.Level, byItem.Expression, item.Sort.Expression);
