There are 3 main standard that Micro$ has developed to interface with
ODBC (age before beauty):
DAO - Database Access Objects
RDO - Remote Database Objects
ADO - ActiveX Database Objects
All three are implemented using OLE (Object Linking and Embedding) at
one level or another. Their interface and tools only differ slightly
between each one. DAO is the oldest and offers the least amount of
functionality.
RDO offers more functionality than its predecessor DAO but at the cost
of speed. ADO was an attempt to utilize the new COM/ActiveX interface
as a speed boost to RDO as well as standardizing features between DAO
and RDO. One major bonus in ADO over RDO or DAO is that you can have a
statement that updates the database and selects from it (think about
it). In RDO and DAO you couldn't have a combined statement that used
SELECT with INSERT, UPDATE, DELETE, or ALTER (very annoying). All three
standards will work in Visual Basic 4.0 and 5.0 as well as Visual Basic
for Applications.
Forgive me for any inaccuracies, I'm not a MSCE.
