Declarative Creation of Enterprise Applications S. Sudarshan IIT Bombay

Database Applications Today Thousands of lines of code and lots of programmer time to generate even simple OLTP applications simple reporting applications Much time/LOC wasted on generating UI and checking constraints that may already be in DB Limitations of current user interfaces How to find interface that does what you want? Can you search for UIs? How to use the interface? How to further play with generated data? Create interfaces on the fly? SQL is difficult Enterprise data vs. web data Optimization of programmer time

Proposal: Declarative Creation of UIs Form creation Data input (esp for OLTP) E.g. Specify DB target of input fields, UI and constraints should be auto-generated If target is procedure, constraints should be propagated from DB to procedure parameters Soft vs. hard constraints  constraint override authorization Declarative specification of simple workflows Declarative specification of authorization

Finding Information Hard to find user interfaces Keyword query to find interfaces? Integrating information from different sources Keyword Queries? Display of keyword query results next page … home page for org. entity vs. home page for topic can this be autogenerated?

Home Page Per Entity? Can we autogenerate this? How about collections of entities?
