The evolution of enterprise application development demanded a shift from traditional two-tier (client-server) models to more scalable, secure, and maintainable n-tier architectures. DataSnap, originally known as MIDAS (Multi-tier Distributed Application Services Suite), was a pioneering framework. In Delphi XE2, DataSnap reached a maturity milestone by fully embracing REST (Representational State Transfer) and JSON (JavaScript Object Notation), moving beyond its COM/DCOM roots. "Delphi XE2 DataSnap Development Essentials" serves as a foundational text for developers aiming to leverage these features.
