OpenWarehouse Q&A
This document is for HP internal usage. It should not be provided to non-HP
personnel. The material in it should help HP personnel in answering questions
posed by the press and consultants.
Q - How does HP's OpenWarehouse compare to IBM's Information Warehouse?
A - Prominent differences between the two programs fall in three areas:
1) Clarity of Vision: Industry analysts (such as Tim Harmon at
Metagroup) agree that IBM has failed to present a clear data
warehousing model. Three or four conflicting models have been
presented by IBM. HP, in contrast, has provided a single, clear
model for helping customers solve their decision support needs.
2) Openness: IBM requires DB2 for Information Warehouse. HP
allows the user to have a choice of popular relational DBMS's.
Information Warehouse on the RS/6000 is currently vaporware. It
will beta ship ("first customer ship") in July and probably will
not be generally available until late 1993.
3) Scalability: IBM provides Information Warehouse scalability
through three processor families: MVS, RS/6000, OS/2. HP
provides scalability through a single processor family: HP 9000
Series 800.
Q - Could you elaborate on the pricing for OpenWarehouse
A - The pricing can vary widely depending on the amount of data stored, the
choice of components, and the number of users. (If you are pressed on this
question, you may want to add that mainframe-based data warehouses can easily
run from $1 million to $10 million. Full OpenWarehouse solutions can run from
about $20 thousand to $2 million.)
Q - What are the future directions for OpenWarehouse?
A - HP will be increasing the portfolio of third parties components certified
under OpenWarehouse. HP also intends to strengthen the network and system
management components of OpenWarehouse. Finally, HP intends to add support for
business modeling to the OpenWarehouse through use of OpenODB, HP's object
oriented database.
Q - What is the relationship between OpenODB and OpenWarehouse?
A - HP intends to add future support for business modeling to the OpenWarehouse
through use of OpenODB, HP's object oriented database. OpenODB has already
been selected as a basis for business modeling by several industry groups, such
as the Petrotechnical Open Software Corporation (POSC).
Q - What is business modeling?
A - Business modeling is a data filtering mechanism that allows a user to
select information based on business concepts that are familiar to him/her. A
business model maps standard or company-specific business terms to the
underlying database structure. (Any further questions on this should be
politely deferred by indicating that HP intends to make further announcements
on this in the future.)
Q - Is OpenWarehouse supported on the HP 3000?
A - Customers can implement a data warehouse on the HP 3000 today. The formal
integration work and consulting services associated with the OpenWarehouse
program will be available to major HP 3000 customers on a demand basis.
Q - Is OpenWarehouse supported on both the HP 9000 Series 700 and Series 800?
A - The formal integration work for the OpenWarehouse program uses the HP 9000
Series 800 Business Servers for the data warehouse. The Series 700
workstations are an excellent choice for clients in an OpenWarehouse solution
and can use either the Andyne GQL data access tool or custom-developed decision
support applications. Custom decision support applications can be easily
developed on the Series 700 workstations using HP Interface Architect or a
variety of other 4GL's and GUI builders.
Q - What role does HP's ALLBASE/SQL play in the OpenWarehouse?
A - ALLBASE/SQL is one of the major relational database management systems
that can be used for the data warehouse under the OpenWarehouse technical
framework. ALLBASE/SQL scales very well in performance for the high-end HP
9000 Model 890 Corporate Business Servers and, thus, appears to be especially
well suited for very large data warehouses (exceeding 100GB).
Q - What part do Oracle/Informix/Ingres/Sybase play in the OpenWarehouse?
A - Any of the major relational DBMS's can be used as part of OpenWarehouse.
HP is initiating talks with the major relational DBMS vendors to determine if a
more formalized relationship would be mutually beneficial.
Q - What security features are supported by OpenWarehouse?
A - OpenWarehouse supports all security features implemented in the relational
DBMS or relational query system used for the data warehouse. This includes
database, table, and field level security. As part of OpenWarehouse
consulting, HP can work with individual businesses to ensure that OpenWarehouse
security is tailored to the individual company's needs.
Q - Can you elaborate on the solution support that HP will be providing for
OpenWarehouse?
A - Because HP has tested and integrated the various components of
OpenWarehouse, HP is able to offer solution support services to meet your
ongoing support needs. With a full range of support services, HP can tailor a
solution support plan that will meet the needs of major companies. With these
customized solution support services, HP can help avoid the perennial problem
of "finger pointing" that customers face when problems involve multiple
products and vendors. (HP Internal Note - The current implementation of
solution support is through Custom Support Plans.)
Q - Does OpenWarehouse support Microsoft's ODBC?
A - Yes.
Q - Does OpenWarehouse support IDAPI?
A - HP is a pragmatic company that seriously works to follow its customers'
desires and market demand. The IDAPI API specification is currently still in a
draft stages. Assuming that IDAPI garners significant market presence, it is
likely that HP will support it in the future as part of OpenWarehouse.
Q - How does OpenWarehouse tie into data dictionaries and repositories?
A - The data warehouse management software allows data definitions for both the
operational databases and the data warehouse to be imported from a wide variety
of integrated CASE tools (such as Bachman, CGI, and KnowledgeWare) and data
dictionaries (usch as BrowStone or RelTech).
Q - What is HP Information Access?
A - HP Information Access is an MS Windows data access and reporting tool that
allows users to easily build graphical queries with no knowledge of SQL.
Information Access supports a very wide range of mainframe, server, mini, and
PC databases. Information Access comes with a full-fledged report writer and
can be used to deliver data to a wide variety of data analysis and presentation
tools through dynamic links (such as OLE and DDE) or various file formats.
Q - How does HP's solution compare with the new massively parallel systems from
NCR, Thinking Machine, etc.?
A - The massively parallel systems are interesting technology, but are largely
unproven in the marketplace. The systems seem to be very good at handling very
complex queries from a single user, but appear to have very poor scalability in
handling more than a few users.
Q - How large of data warehouses can be handled by HP's OpenWarehouse?
A - The HP 9000 Model 890 Corporate Business Server can handle up to 1.2
terabytes of data. We are currently setting up tests to determine whether
there are any software or practical limitations in supporting data warehouses
up to that size.
