8. Creating Crystal Reports
Understanding Crystal Reports
• Crystal Reports is the standard reporting tool for Visual Studio .NET used to
display data of presentation quality.
• Creating a Crystal Report requires minimal coding since it is created in a
Designer interface.
©NIIT Creating Data Centric Application Using ADO.NET Lesson 2B / Slide 8 of 30

9. Creating Crystal Reports
Data Access Through Crystal Reports
• Crystal Reports need database drivers to connect to the data source for
accessing data.
• Crystal Reports in Visual Basic .NET support two methods to access data from
a data source:
• The Pull Model
• The Push Model
©NIIT Creating Data Centric Application Using ADO.NET Lesson 2B / Slide 9 of 30

10. Creating Crystal Reports
The Pull Model
• When Pull model is used to access data from the data source, the database
driver directly retrieves the data from the data source.
• Pull model does not require the developer to write code for creating a
connection and retrieving data from the data source.
• The Crystal Report creates and manages the SQL commands for connecting to
the data source and retrieving data from it.

11. Creating Crystal Reports
The Push Model
• In this model, the developer writes the code to connect to the data source and
retrieve data from it.
• The data from the data source is cached in a dataset.
• the Push model allows filtered data access by Crystal Report.
• The Push model is generally useful for connection sharing scenarios.
