Summary
DataSet
A DataSet is an in-memory representation of data. This is a separate cached set of records retrieved from the database. After connecting to the database, the data adapter creates a dataset and populates it with data. Once the data has been retrieved and saved to the record, the connection to the database is closed. This is called a "disconnected architecture". A dataset acts as a virtual database containing tables, rows, and columns.
