Connected and disconnected architecture in ADO.Net with Example

Connected Architecture of ADO.NET The architecture of ADO.net, in which connection must be opened to access the data retrieved from database is called as connected architecture. Connected architecture was built on the classes connection, command, datareader and transaction.  Connected architecture is when you constantly make trips to the database for any CRUD (Create, Read, Update and Delete) operation you wish to do. This creates more traffic to the database but is normally much faster as you should be doing smaller transactions. Disconnected Architecture in ADO.NET The architecture of ADO.net in which data retrieved from database can be accessed even when connection to database was closed is called as disconnected architecture. Disconnected architecture of ADO.net was built on classes connection, dataadapter, commandbuilder and dataset and dataview. Disconnected architecture is a method of retrieving a r...

You can use a self-join to simplify nested SQL queries where the inner and outer queries reference the same table . These joins allow you to retrieve related records from the same table. The most common case where you'd use a self-join is when you have a table that references itself I have the employee detail table, In that i want to find the manager for each Employee . The employee nam e and manager column are present in same table Consider the following Employee table CREATE TABLE Employee (     Emp_Id INT IDENTITY ( 1 , 1 ) NOT NULL PRIMARY KEY ,     Emp_Name VARCHAR ( 100 ),     Manager_Id INT NULL ) INSERT INTO Employee ( Emp_Name , Manager_Id ) VALUES ( 'a' ,null) INSERT INTO Employee ( Emp_Name , Manager_Id ) ...
