What should they be: view or virual models?
by Paul Nittel
Some time, way back in the MetaMatrix days, we changed our nomenclature to refer to "view" instead of "virtual" models. I see the word "virtual" creeping back a bit. Personally, I prefer "virtual" since "view" can be verb-ish. Yes, they are kinda like views in the database world.
Anyway, Jopr lists these models as "virtual". Is that politically correct?

"Virtual" in Jopr represents the Enumerated value for model type coming back from Teiid. If "View" is the required terminology then the Enumerated value needs to be changed.

view was the supposedly correct term, but doesn't map exactly to the db world, since view implies table and our "view layer" is a whole schema including procedures. I would personally like to see the word "view" applied only the way databases do.

7.0 release status
by Steven Hawkins
Hello all,
Unless there are any objections, I would like to proceed with the 7.0 release today. In any case there should be no check-ins on the 7.0 branch unless absolutely necessary. Also please have a look at any resolved, but not yet closed issues to see if they should be closed. There will be a lot of teiid.org updates to follow.

7.0 release status
by Steven Hawkins
Hello all,
We have made excellent progress of 7.0. Ramesh has done a great job collecting together new documentation and ensuring that the Salesforce logic functions correctly. The Designer Team has picked up our build as of Thursday and so far so good. We should make a determination today as to whether we want to release 7.0 tomorrow or cut an RC3 and wait.
7.1 development is also underway. Be sure to work enhancements early as it is rather short cycle.

Re: [teiid-dev] PostgreSQL Sequences
by Steven Hawkins
Hi Jimmy,
What type of sequence support are you looking for? Full language support?
For Oracle, in designer a sequence may be modeled as a table with a name in source of dual and columns with the name in source set to <sequence name>.[nextval|currentval]. You can use a sequence as the default value for insert columns by setting the column to autoincrement and the name in source to <element name>:SEQUENCE=<sequence name>.<sequence value>. The latter is more of a workaround though, rather than a good solution.
It seems like we would need to extend that support for PostgreSQL and other databases supporting sequences. We should also think about getting sequence information as part of dynamic vdb metadata so this isn't a manual exercise.
For documentation we're always looking for more wiki content, examples, etc. The newer documents, like the admin guide, may be a little lite. So if you see anything omitted, let us know.
Steve

Subject: [teiid-dev] PostgreSQL Sequences
Quick question: Will teiid ever support sequences in postgres or oracle?
BTW, Theres lots of good work going on here -- CR2 looks good.
Is there some documentation I could help writing?

7.0 CR2
by Steven Hawkins
Hello all,
Today we will post CR2. It contains several fixes and substantial cleanup of the docs. We'll also branch later today so that trunk will become 7.1.

I wonder it it wouldn't be better to require the user to envelope the SOAP message? This would enable us to provide the WS-* headers as other system or UDF functions that could put the appropriate values in the document.

This was done to allow access to REST like sites that served up the same XML at different URLs ( ../Employees/1.xml && ../Employees/2.xml)
