Minutes from the meeting of 7/2

Attending: Serge,Jason,Yue,Michael,Vasilis,Janet

We came up with a to-do list:

0. Define the problem:
	We intend to develop an incremental view maintenance algorithm
	for materialized OEM views and study related research issues.
	The inputs of the algorithm are:  view definition, base database
	and atomic base object updates (edit scripts in DOEM).
	The output of the algorithm should be changes of the view (what are
	they and how to apply them.)

1. Design a more detailed algorithm for
	- views with simple paths    ( By 7/9, Vasilis, Jason)
	- with with complex paths	( Vasilis, Jason, Michael)

2. Analyze the complexity of the algorithm:
	- by example			(By 7/16, Janet)
	- by some model			(By 7/16, Janet)
	- by experiment			(after implementation)

3. Optimizations: (By 7/16, Michael)
	- compile time optimizations
		* use update statement (Jason, Michael)
		* use data guide (Michael)
	- run time 
		* access structure (Serge)

4. Implementation: use lindex and existing lore functions (Jason)
