This information was originally created for the XE version of RAD Studio. It also applies to RAD Studio XE2.
Embarcadero® RAD Studio XE is the most popular release in years, in large part due to DataSnap XE. The DataSnap® framework, in the Enterprise, Ultimate and Architect editions of Delphi, C++Builder and RAD Studio, enables you to build multi-tier applications with the server built in Delphi and C++Builder, and connect with them via a wide variety of clients and protocols. Join Embarcadero and Bob Swart for a walk through a real world DataSnap application, covering topics like security, authentication, and deployment.
Bob Swart presents: DataSnap XE in the real world
In this webinar, we'll see how to create a small but real-world DataSnap Server and client application, including security and deployment details. Security details that are demonstrated include authentication (login, who can access the server) and role-based authorization (who can execute which server methods), including authorization rules for exported TDataSetProviders.
The DataSnap Server is shown to expose both simple server methods, server methods that expose read-only data (using a TSqlServerMethod component at the client side) as well as exported TDataSetProvider with master-detail nested datasets. To make things even more interesting, the datasets are using autoincrement primary keys.
Topics that are covered include:
- Creating DataSnap server in Delphi, examining possible server targets and deployment strategies
- Adding security using Authorization (login) and role-based Authentication (for server methods and TDataSetProviders)
- Exporting and updating nested-datasets using autoincrement primary keys

DataSnap XE Server
In this video, Bob demonstrates how we can use the new Delphi XE DataSnap wizards to produce a DataSnap Server project skeleton. He discusses the possible options, their effect, and uses the wizard to start a real and secure DataSnap XE server project.
DataSnap Server Security
In this video, Bob shows how we can add security to a DataSnap XE server application, using both Authentication and Authorization. For Authentication, we’ll implement login, determining the user’s true identity using the OnUserAuthenticate event handler. For Authorization, we’ll use a pessimistic Role Based User Authorization, where you are not able to call anything, unless explicitly allowed.
In this video, Bob demonstrates how a DataSnap client application can connect to the server in a secure way, and how both the authentication and authorization is satisfied in order to be able to call server methods and use exporter TDataSetProviders.
