Tuesday-5

Today in class we talk about dataview which is a different way to look at the data table. Relatonal database, SQL, and ADO (active data object) is how to manipulate data, execute query, store data. OLEB talks to the database and the ADO talks to the OLEB and the application. Five objects of the ADO is the connection, DataAdapter, Command, DataReader, DataSet. Four methods for the command object is the executenonquery,executereader,executescaler, and the connectionobject. We also talk about the Primary key and then watch the new version of visual basic the 2005 visual basic video on the MSDN website. Well, that is all for now until next time.
