Hilda: A High-Level Language for Data-DrivenWeb Applications

We propose Hilda, a high-level language for developing data-driven web applications. The primary benefits of Hilda over existing development platforms are: (a) it uses a unified data model for all layers of the application, (b) it is declarative, (c) it models both application queries and updates, (d) it supports structured programming for web sites, and (e) it enables conflict detection for concurrent updates. We also describe the implementation of a simple proof-ofconcept Hilda compiler, which translates a Hilda application program into Java Servlet code.
