Re: Generic Collection

[andrew <andrew.carroll@okstate.edu>]

Actually I take that back.  RDB2 looks promising with respect to how I
have my program now.  What I want is to be able to change my program
so that I can declare table, tuple and schema to be of a "collection"
type like:

table: collection;
tuple: collection;
schema: collection;

The collection would have to be a common object as in the sense of
Object in Java.  So here is an expanded pseudo-code example:

attr1 : attribute;
attr2 : attribute;
attr3 : attribute;

attr4 : attribute;
attr5 : attribute;
attr6 : attribute;

table1 : collection;
table1.add(attr1);
table1.add(attr2);
table1.add(attr3);

table2 : collection;
table2.add(attr4);
table2.add(attr5);
table2.add(attr6);

Or, if I had run a query where I projected attributes out of a table I
could use:

tuple : collection;

and fill it like I did the table.

Then, schema could be a collection of tables or tuples like:

schema : collection;
schema.add(table1);
schema.add(table2);

This again would depend on being able to use a common object like Java
has.

What do you think?
