If you want to get an idea of how many rows of data are in your tables in your database, connect to the database and run this query:
SELECT t.name, s.row_count from sys.tables tJOIN sys.dm_db_partition_stats sON t.object_id = s.object_idAND t.type_desc = 'USER_TABLE'AND t.name not like '%dss%'AND s.index_id IN (0,1)
