to incorporate visual design and runtime management of complex business and
integration processes that may be automatic or require human intervention.
Business Process Management (BPM) enables the centralization of business
processes on a NonStop Server with that server acting as a hub for all the information.
There are a number of other products that support BPM on HP NonStop servers:
•
The SeeBeyond eGate 5 Integrator product is now shipping on NonStop servers
and is based on standard Java technology. This product is popular in the
healthcare industry, with strong support for standard Health Level 7 (HL7)
protocols.
•
The HP Real Time Information Director (RTID) is based on standard Java and XML
to provide data management services for a ZLE Data Store. RTID provides data
cleansing and enrichment, as well as data security, and ensures data integrity
while acting as a gateway between supply-chain, financial services, or healthcare
applications and the ZLE Data Store. It supersedes the ZLE Development Kit
(ZDK) that provided some of RTID functionality in C/C++.

•
Web services are being rapidly adopted on NonStop servers as enterprises are
realizing the benefits of a hub-based approach versus fully distributed
environments. Infravio's Ensemble offers such hub-based Web services as an
integration environment that can be better secured and managed.
•
Data integration is a critical part of enterprise integration projects. Very high-
performance data extracts and loads are possible between NonStop SQL
Databases (ZLE Data Store) and other platforms such as Oracle for data mining or
other business intelligence purposes. Genus' High Speed Data Connectivity
Infrastructure for NonStop SQL enables very high performance (hundreds of
GB/hour) to be extracted or loaded into a NonStop SQL Database. Vendors such
as Ascential and Informatica use that capability to integrate data between
applications such as NonStop SQL Software and Oracle, DB2, Microsoft SQL, and
mySQL.
Standards and Web Services
Web services provide a new standard for intersystem messaging and commerce using
the Web. Web services is a new form of an old technology that we are familiar with.
Client/server has morphed into an asynchronous request/response approach, where
application services are offered by a provider and used by a consumer. For example,
think of an ATM machine that also provides maps to nearby restaurants. The bank
uses one Web service to get information on a nearby restaurant and another Web
service to obtain appropriate map directions. Thus, applications look like a set of
services and the satisfaction of those services may be distributed globally.
