     It is a gem with following options to check sanity of database
         # All data in all models
         # Random data in all models :
             * specify n number of random records,
             * specify criteria
+    It allows you to see details in two strategies - table/csv
+        # output to a model named DataInspector
+            * For this you need to run migrations
+            * You get an advantage of using variable from command line

 # HOW TO USE
-    * adding migrations : rake data_sanity:db:migrate
-    * removing migrations : rake data_sanity:db:rollback
-    * Use normal rake db:migrate to migrate the migration added by rake data_sanity:db:migrate
+    
+    * adding migrations : rake data_sanity:db:migrate [for strategy table]
+    * removing migrations : rake data_sanity:db:rollback [for strategy table]
     * You can add a sample criteria file using rake data_sanity:criteria
     * To Investigate your data use rake data_sanity:investigate
-        - By default it runs for all data
+        - By default it runs for all data with strategy table
             : If criteria file is specifies then picks model from file and validates only those
             : Note: For any criteria mentioned except model names is ignored
-        - rake data_sanity:investigate[random,2]
+        - rake data_sanity:investigate[table,random,2]
             : parameter 1: random: show you want random selection
             : parameter 2: lets you add as many random records you want to verify [default is 1]
             : Note: if you have a criteria file it works only for models in criteria file
+        - rake data_sanity:investigate[csv,random,2]
