 System.Data TODO List
 =====================
 
-This TODO list last updated on 2002-04-23

 Update this file as needed...
 
 * To get ExecuteReader() in a SqlCommand object to return 
   a SqlDataReader object which can Read() data and get a String or
   Int32 from the database.  Other types can be done later.
-
-In order to do this, we need to compile 
-       SqlDataReader 
-       DataTable
+  
+  A class (SqlDataReader) that implements IDataReader/IDataRecord
+  only has one row in memory at a time.

+In order to do this, we need to compile and edit these classes:

-MSDN has the classes: 
-       DataRelation, DataRelationCollection, DataTable, DataTableCollection
-
-Mono has the classes:
-       DataRelationCollection, DataTable, DataTableRelationCollection
-
-Something is not right here:
-       maybe mono's DataTableRelationCollection 
-       was suppose to be DataTableCollection
-
-        This would mean that DataRelation is missing.
-
-Other classes missing:
-       * InternalDataCollectionBase - this is a public class despite its name
-       * DataRowBuilder
-       * Constraint
-       * ConstraintCollection

 System.Data.Common classes that need to be implemented:
  - implement DataAdapter.cs
  - implement DataColumnMapping.cs
