√ √ √ Command object (This is the responsible object to use stored procedures) Data Adapter (This object acts as a bridge between datastore and dataset). Datareader (This object reads data from data store in forward only mode). Dataset object represents disconnected and cached data.If you see the diagram it is not in direct connection with the data store (SQL SERVER , ORACLE etc) rather it talks with Data adapter , who is responsible for filling the dataset.Dataset can have one or more Datatable and relations. Figure :- 9.1 ADO.NET Architecture 174 * Not answering simple ADO.NET questions can lead to negative results.
“DataView” object is used to sort and filter data in Datatable. Note:- This is one of the favorite questions in .NET.Just paste the picture in your mind and during interview try to refer that image. (B)What are the two fundamental objects in ADO.NET ? Datareader and Dataset are the two fundamental objects in ADO.NET. (B)What is difference between dataset and datareader ? Following are some major differences between dataset and datareader :- √ √ √ DataReader provides forward-only and read-only access to data , while the DataSet object can hold more than one table (in other words more than one rowset) from the same data source as well as the relationships between them. Dataset is a disconnected architecture while datareader is connected architecture. Dataset can persists contents while datareader can not persist contents , they are forward only. (I)What are major difference between classic ADO and ADO.NET ? Following are some major differences between both √ √ As in classic ADO we had client and server side cursors they are no more present in ADO.NET.Note it's a disconnected model so they are no more applicable. Locking is not supported due to disconnected model. √ All data is persisted in XML as compared to classic ADO where data was persisted in Binary format also. (B)What is the use of connection object ? They are used to connect a data to a Command object. √ An OleDbConnection object is used with an OLE-DB provider * Why do you want to leave this company ? (Never say anything negative about your past company) 175
