Previous development process(DNN 3)

• Configuration was difficult
• Data Access Layer was difficult to understand

8
New development process(DNN 4)

• Configuration is no longer needed using the new
  ASP.NET 2.0 Website project model
• The DAL simplifies the Data Access Layer

9
The DAL

• You no longer have to code a separate data
  provider
• It adds Generic Methods to ease module
  development.
• ExecuteNonQuery - Used to execute a stored
  procedure that will not return a value.
• ExecuteReader - Used to execute a stored
  procedure that will return multiple records.
• ExecuteScalar - Used to execute a stored
  procedure that will return a single value.
• ExecuteSQL - Used to execute an sql statement.
