OpenWire is a free open source library for writing advanced VCL components, capable of exchanging data and events without the need of additional code. The components written with OpenWire allow creation of complex software without writing any code. The technology allows the components to establish data and event connections trough special properties called pins. By visually establishing the connections the developer effectively does the programming. This session covers the design of OpenWire, writing basic and advanced OpenWire components, and demonstrates real components written with the technology.
Refactoring is the science (and art) of improving the design of code without changing its behavior. This presentation teaches a few basic refactoring techniques, but more importantly teaches you when and why to use them, and what to tell your manager.
Migration from Client/Server to Multi-tier with DataSnap and Delphi
Vsevolod Leonov – Embarcadero
Relevant to: Delphi, RAD Studio
DataSnap platform for multi-tier provides powerful capabilities for developers. Now it’s easy to start a new multi-tier project with many variants of deployment. But sometimes the goal is to convert the existing Client/Server project into DataSnap version. Sometimes it needs the migration of the code style into pattern, typical for multi-tier programming. So we have a traditional project, implementing interaction with DBMS. How can we support migration? What should be easily change and what needs some refactoring? The presentation will consider the basic and reliable techniques, which will help you to upgrade the existing projects and get the advantages of new DataSnap multi-tier architecture.
