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...

Overriding Overloading Methods name and signatures must be same. Having same method name with different Signatures . Overriding is the concept of runtime polymorphism Overloading is the concept of compile time polymorphism When a function of base class is re-defined in the derived class called as Overriding Two functions having same name and return type, but with different type and/or number of arguments is called as Overloading It needs inheritance. It doesn't need inheritance. Method should have same data type. Method can have different data types Method should be public. ...
