When extended with the downloadable IBM Integration Module,
the IBM Optim pureQuery Runtime simplifies the process of generating
DB2 static SQL for Hibernate and iBATIS applications.
It does this without requiring you to make changes to your application code or
to gather SQL from production workloads.
The Optim pureQuery Runtime also enables Hibernate
and iBATIS applications that access DB2 or Informix to benefit from the heterogeneous
batching feature in pureQuery.
With the heterogeneous batching feature, you can batch multiple INSERT,
UPDATE, and DELETE requests before sending them across the network, even when the requests reference multiple tables.
This article is part one of a two part series.
It describes using the IBM Integration Module with Hibernate applications.
Part two will focus on iBATIS applications.
This article includes
a downloadable sample application that illustrates how you can easily enable both these
capabilities.
The article also provides informal elapsed time performance measurements.

XML is increasingly becoming common as a means for information exchange. A web
service application is an example of the type of application that uses XML to exchange information.
Any business intelligence product or solution must have sufficient capability to query information
that could be in the form of XML. Learn how
IBM Cognos 8 delivers a comprehensive, flexible, secure, and scalable solution to query
and report on XML data sources, including web services, by leveraging the IBM Cognos
Virtual View Manager.

Learn about advanced query statistics, a new feature introduced in IBM
OmniFind Enterprise Edition V9.1, based on query log index technology. This
new feature offers access to three critical types of statistical information
about searches executed using OmniFind: changes in query activity over time,
popular queries issued by users, and query history. By monitoring and
analyzing these statistics, you can gain insights that enable you to enhance
search performance and improve the quality of search results.

This second article in the series focuses on the integration of
InfoSphere(TM) Streams and WebSphere(R) ILOG(R) JRules. InfoSphere Streams is
a high-performance stream processing engine that is capable of performing
calculations and analysis of data streams in real time. ILOG JRules is a
business rules management system that enables the creation of rule-based
applications. This article presents a simple, algorithmic trading scenario in
which InfoSphere Streams operate on a stream of market data and, under certain
circumstances, a business rule is invoked using ILOG JRules. In order to
perform this task, you will learn how to integrate the two products together
in an efficient manner.

Many companies need an out-of-the-box solution for integrating IBM
FileNet Business Process Manager (BPM) and IBM Content Manager V8 (CM8).
Today, using new capabilities provided by IBM Enterprise Content Management
Widgets (ECM Widgets) 4.5.2 and IBM WEB Interface (WEBi) 1.0.4, IBM's
Enterprise Content Management products bring you an easy way to integrate BPM
and CM8 at the runtime tier. Using these new features, enterprise business
analysts can manage their business processes using CM8 content without having
to invest any additional development effort. This article describes the
business background, the architecture, and the procedures for integrating BPM
and CM8 repositories at runtime.
