How would I store an OLE object into a database's blob field and preferably be able 
to read it back in a usable form later on?

Answer:

To write a TOLEContainer to a blobfield:

1   var
2     Stream: TBlobStream;
3   begin
4     Stream := TBlobStream.Create(myOleField, bmWrite);
5     try
6       Ole1.SaveToStream(Stream);
7     finally
8       Stream.Free;
9     end;
10  end;
11  
12  //To read it back:
13  
14  var
15    Stream: TBlobStream;
16  begin
17    Stream := TBlobStream.Create(BugData.NotesNote, bmRead);
18    try
19      Ole1.LoadFromStream(Stream);
20      Ole1.Iconic := False;
21    finally
22      Stream.Free;
23    end;
24  end;


Where you put the code is up to you, but the DataChange and UpdateData events of the appropriate TDatasource might be a good idea.
