Understanding data access objects is crucial for creating robust and efficient .NET applications.
Key components include: Entity, DataAccessObject, DatabaseConnection, and DataRow.
Entity represents the data you're working with.
DataAccessObject is the concrete representation of a specific data type.
DatabaseConnection allows you to connect to a database and retrieve data.
DataRow contains the relevant data for a single record.
Create an Entity class to represent your data.
Define the DataAccessObjects within the Entity class.
Establish a DatabaseConnection to interact with your database.
Use DataRow to manage the data.
Create a simple Entity class for a customer.
