Minutes from the meeting of 4/130/97

Attending: Roy,Vasilis,Jason,Yue, Michael,Janet,Matt

Topic: Yue's report about her work on materialized OEM views with Hector

Major points:

1. The OEM model used is slightly different from the one used in this
group. They have objects as records with OIDs, and labels are within 
objects. However, this difference is not fundamental. 

2. They assign a virtual database object for each database. This
database object has type set and has the set of OIDs of all objects in
the database as its value. Furthermore, a query result is also a set object.

3. A view is defined to be the result of a view definition query, which 
is an object (which is also a database). Edges are preserved implicitly.

4. There are a list of database (view) operations, like union, difference, etc.

5. Maintenance is simple.

6. They can not explictly manipulate edges.
