ADO and ADO.NET are different in several ways:

·         ADO works with connected data. This means that when you access data, such as viewing and updating data, it is real-time, with a connection being used all the time. This is barring, of course, you programming special routines to pull all your data into temporary tables.

ADO.NET uses data in a disconnected fashion. When you access data, ADO.NET makes a copy of the data using XML. ADO.NET only holds the connection open long enough to either pull down the data or to make any requested updates. This makes ADO.NET efficient to use for Web applications. It's also decent for desktop applications.

·         ADO has one main object that is used to reference data, called the Recordset object. This object basically gives you a single table view of your data, although you can join tables to create a new set of records. With ADO.NET, you have various objects that allow you to access data in various ways. The DataSet object will actually allow you to store the relational model of your database. This allows you to pull up customers and their orders, accessing/updating the data in each related table individually.

·         ADO allows you to create client-side cursors only, whereas ADO.NET gives you the choice of either using client-side or server-side cursors. In ADO.NET, classes actually handle the work of cursors. This allows the developer to decide which is best. For Internet development, this is crucial in creating efficient applications.

·         Whereas ADO allows you to persist records in XML format, ADO.NET allows you to manipulate your data using XML as the primary means. This is nice when you are working with other business applications and also helps when you are working with firewalls because data is passed as HTML and XML.

There is one more point I would like to add:In Ado.net, Data Binding (linking data source to data consumer) is possible with the help of DataGrids and DataLists.This makes organizing and displaying data faster and more efficient.

Recordset contains result of a database query, It is not used to display the data from the database. We use recordset in ADO technology.

Datagrid is used to only display data from database not to contain data.

1. Ado.net is a disconnected  architecture

   Ado is not support to disconnected architecture

2. ADO allows you to create client-side cursors only, whereas ADO.NET gives you the choice of  either using client-side or server-side cursors.

3. Whereas ADO allows you to persist records in XML format, ADO.NET allows you to manipulate  your data using XML as the primary means

I need a clarrification. If ADO.NET is disconnected, ie., if data from database is moved to DATASET using DATAADAPTER's FILL method, if any other user /  from some other apps data updated to the same table, how do the DATASET get the UPDATED data from database.

In simple, how to ADO.NET handles database concurrency....???

as you know that ado.net is disconnected mode.
in case you want to update the data in database frequently in this case it is better to use ado

data adapter worked on the disconnected model.
when we work on the disconnected model we use data adapter to fetch the data from the database domain.
so when you fetch data with data adapter then updated data is fetched

1.
ADO- Connection-Oriented Architecture
Use Record Set
Communicate in Binary mode
Ado.net Dis-connected architecture
Use DataSet,Adapter
Parse Data in XML mode
2.
ADO was a connected data access model, which means that when
a connection to the database is made, the connection remains
open until the application is closed.
ADO.NET is disconnected database access model, which means
when an application interacts with the database, the
connection is opened to serve the request of the
application, and is closed as soon as the request is completed.
All data is presented in XML, as compared to ADO.

ADO use only OLEDB and it is COM based technology.ADO use tabel log and user log
ADO.NET is Built-in technology.it provide Data binding link between Data source controls.
