Relevant to: Delphi, Delphi Prism
In this session, learn how to use Delphi for Win32 as well as Delphi for .NET to develop multi-tier applications that consist of middleware server applications and thin- or smart-clients (stand-alone executables). See a demonstration of the use of the RemObjects SDK to define the server interface with the Service Builder and the different channel and message components, explaining their use and benefits, as well as special security details (encryption and compression). Also covered are Data Abstract in combination with RemObjects SDK, in order to build data-driven multi-tier applications. Benefits of using thin/smart-clients are covered in detail including the fact that these are "internet-enabled applications", with a rich GUI, and without the need for a Web browser!
In order to use the ADO.NET Entity Framework effectively, you must understand its value-based data model, which is distinctly different from the SQL and ORM approaches to representing and querying data. Programmers who approach the Entity Framework as "just another ORM" often find themselves frustrated or disappointed, a common reaction to trying to force a square peg into a round hole. This presentation examines the Entity Data Model in-depth, explaining where it fits into the context of a larger application, and demonstrates different techniques for retrieving and altering data. Also covered are performance considerations and future directions.
Getting Intimate with Your Newly Inherited Database
Rick Iannitelli – Embarcadero
Relevant to: All-Access
Current economic trends provide ample opportunity for firms to either acquire new IT assets or divest themselves of them. Therefore, DBAs will have newly acquired databases dropped in their laps, and asked (better said, told) to understand them and pick up the ongoing support. With the technology stack that Embarcadero provides through All-Access, DBAs can quickly and easily get an understanding of these newly inherited databases. Create visual representation of the database, capture and archive all database objects in order to mitigate the risk with ongoing development of the database, and even go as far as understand the resource utilization of these databases.
