Write high performance, Java data access applications, Part 2: Introducing pureQuery inline method style
IBM pureQuery is a high-performance Java data access platform focused on simplifying the tasks of developing and managing applications that access data. It consists of tools, APIs and a runtime engine. pureQuery introduces two programming styles to help users access the database through simple but powerful APIs. This article introduces one such style, the inline method programming style, and discusses how users can use it to efficiently query and update databases. This article also explores the benefits as well as some of the key features of using the inline method programming style.

Write high performance, Java data access applications, Part 1: Introducing pureQuery annotated method style
pureQuery is a high-performance Java data access platform focused on simplifying
the tasks of developing and managing applications that access data. It consists of tools, APIs and a runtime. This article introduces the pureQuery annotated method coding style -- a simple, flexible style falling under the named-query paradigm, capable of executing SQL statically or dynamically. This article explains why a developer might choose to write a pureQuery application in the annotated method style, explains some of the differences between the annotated method style and the pureQuery inline coding style, and gives a brief overview of the most powerful features of pureQuery annotated methods.

A performance comparison of DB2 9 pureXML and CLOB or shredded XML storage
Like other databases,
the DB2 V8 XML Extender offers two storage and access models for XML: XML documents
can be stored intact as unparsed text in CLOB columns, or they can be mapped and
shredded to a set of relational tables. Both options have known performance
limitations. The new pureXML technology in DB2 9 seeks to overcome these limitations
by storing and querying XML in its inherent hierarchical format. This article
describes a series of measurements to characterize the cases in which pureXML does or
doesn't provide a performance benefit, and to quantify the performance difference to
CLOB or shredded storage.

Exploit XML indexes for XML query performance in DB2 9
DB2(R) 9 provides pureXML storage and offers XQuery and
SQL/XML as query languages. XML indexes are essential for high query
performance, but their usage for query evaluation depends on how query
predicates are formulated. This article presents a set of guidelines for
writing XML queries and creating XML indexes in a consistent manner so that
indexes speed up your queries as expected. Also learn what to look for in XML
query execution plans to detect performance issues, and find out how to fix
them. A downloadable "cheat sheet" summarizes the most important guidelines.
This article has been updated for DB2 9.5 and 9.7. [2009 Jul 30: This article has been updated for DB2 9.5 and 9.7, including

DB2 9 has sophisticated XML indexing capabilities and support for XML Schema
validation. While most existing performance guidelines for DB2 also apply to
XML data, this article provides additional XML-specific performance tips. This article has been updated for DB2 9.5. [2009 May 26: Corrected code in Listings 12 and 13.--Ed.]

Top 10 performance tips
Every few weeks or so, we get performance calls from DBAs in distress. "Our Web site is crawling," they bemoan. "We're losing customers, and the situation is dire. Can you help?" To answer these calls, I've developed an analytics process for my consulting company that letsus rapidly find the cause of performance problems and develop remedial actions and tuning suggestions. Rarely do these callers inquire about fees or costs - they're only interested in stopping the bleeding. When a DB2 or e-business application isn't performing up to expectations, the entire organization and financial bottom line measurably suffers.

Using virtual cubes in IBM InfoSphere Warehouse 9.7 to combine business
scenarios and to improve performance
Virtual cubes are one of the new Cubing Services features in IBM
InfoSphere(TM) Warehouse 9.7. A virtual cube provides a way to merge different
cubes together to allow a single query destination that returns merged results
from the cubes that compose it. Virtual cubes can be used to drastically
improve the response time of the cube server queries by using efficient data
partitioning for optimum cache utilization (in some cases, over 100 times
better response times). Virtual cubes also offer a solution for combining
results by merging different regional cubes into a country cube. They also
enable merging sales numbers with currency exchange rates to provide a global
view of the business. This article explains how virtual cubes are created, how
they work, and how to use them for InfoSphere Warehouse Cubing Services
9.7.
