Re: Modernization? -- WEB400

Regarding better performance, the article indicated that database objects were reference by "pointers" which appears to be another way of saying "record level access", which is used by RPG programmers every day. Evidently, we have a futuristic DBMS.

In his original post, Roger Harman referenced a message from a migration vendor which implied that modernization meant a change in:

1. Hardware platform
2. Operating system
3. Database management system
4. Programming languages
5. Integrated development environment & related tools
6. 2-tier architecture to multi-tier.

But they promised a streamlined migration. Is anyone buying that?

It was interesting to me that OODBMS was an idea that was first
mentioned at least as early as 1980 (or somewhere back there) -
according to the wiki article that Maurice cited. The same article
claims better performance for certain kinds of queries with OODBMS,
although it is maybe not so good for ad hoc stuff - best if you ask it
for information as it is stored.

The American Heritage Dictionary defines the word futuristic as:

The same dictionary defines the word modern as: "Characteristic or
expressive of recent times or the present; contemporary or up-to-date."

It seems to me that OODMBS and the NoSQL movement are more futuristic
than modern. And it seems to me that RDBMS are still modern.

A system does not have to be futuristic to be modern.

My 2 cents...

I don't think OODBMS is the next big revolution. With the rise of
virtualization and clustering has come a set of database technologies
that fall under an umbrella called "NoSQL":

http://en.wikipedia.org/wiki/nosql

Many of these are derived from concepts originating in Google's work
with BigTable, although there are some much older technologies (IMS)
included. It just goes to show the cyclical nature of technology.

Sounds like you have a product - if so, please say so. Your comments
come across very skewed.

No product, I just have a very basic Prototype OODBMS put together some
years ago. I have no criticism of the databases mentioned, all I would
say
is that RDBMS has been around for quite a considerable time and with the
expansion of OO programming languages then it would appear natural that
an
OODBMS would come along next (maybe we are ready for it now?). Possibly
this
then could be referred to as a "Modern" approach to the database and one
that works more akin to the human brain (I don't think mine stores
tables..., but who knows ;-)

Certainly there is room for both RDMS and OODBMS and its not one versus
the
other. It is a topic that I am very interested in, more at
http://en.wikipedia.org/wiki/Object_database#

Hope this clarifies my comment a little bit and I do apologise if it was
skewed.

Maurice

It would take some discussion for me to put forward my ill founded

thoughts

on what a modern database should be. But if someone tells me that a

20th

century database (based on the thoughts of Dr. Edgar Frank Codd "Ted")

is

modern then I have to question it? It was a good idea in the day and

now
our

systems are built over it (not just DB2 but also SQL Server, MySQL,

Oracle

etc). It is far too large a subject to discuss on this list (and I'm

likely

to be burned at the stake....) but personally I believe the next big
revolution will involve the database (we've had improvements

everywhere

else).

Cellular and fast, I have a prototype ;-)

Maurice and all,

One would infer from your message that you have some concerns about

DB2i

or IBM i being "Modern". Can you share what you believe might be
lacking in these regarding what may be considered modern? I am
currently sitting in CAAC Requirement meetings in Rochester and would

be

happy to include requirements by you and the community at large for

IBM

to consider.

Please lay off the marketing shtick, I ain't beating that horse in

this

venue. See iManifest for more details on that.

Regards,

Mike

I suppose it depends on what your definition of modern is.

It's good yes, but modern??

Thought I'd share an email I received and my response......

Thanks for the offer. However, we already have a "modern
industry-standard platform" . IBM i on Power - which includes a

modern

relational database.
