DataSet, DataReader, and ADO. netdatareader In ado. NET ADO. NET provides two objects for retrieving relational data and storing it in the memory: DataSet and DataReader. DataSet provides a full set of relational data in the memory, including the relationships between tables, such as tables, order, and constraints. DataReader provides fast, forward-only, and read

Summary: Ado. Net is a data-intensive application.ProgramIt provides a variety of technologies to simplify the process of establishing such programs. A dataset (Dataset) serves as a flag of the ADO. Net object model and as a copy of a micro, unconnected data source. Although using a dataset improves performance by reducing the high-cost access to the database ser
