1. Declarative Creation of Enterprise Applications

2. 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

3. 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

4. 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?

5. author (near concurrency)
“christos papadimitriou” concurrency

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

7. BANKS Project Keyword search on graph structured data Earlier work
Algorithms for efficient search on
in-memory data (ICDE02, VLDB05)
external memory (disk) data (VLDB 08)
distributed memory graphs (cluster) (Ongoing work)
