Mastering OLAP Reporting: Meet Business Needs with Matrix Dynamics, Part II

About the Series …

article, Part Two of
OLAP Reporting: Meet Business Needs with Matrix Dynamics
, is a member of the series MSSQL Server Reporting
. The series is designed to introduce MSSQL Server Reporting
("Reporting Services"), with the objective of presenting
an overview of its features, together with tips and techniques for real-world
use. For more information on the series, please see my initial Database Journal article, A New
Paradigm for Enterprise Reporting

As I
have stated since the charter article of the series, published about the time Reporting
was first publicly released, my conviction is that Reporting
will commoditize business intelligence, particularly in its role
as a presentation component within an integrated Microsoft BI solution.
Having been impressed from my first exposure to this exciting application, when
it was in early beta, my certainty in its destiny grows stronger by the day, as
I convert formerly dominant enterprise business intelligence systems, such as Cognos,
Business Objects, MicroStrategy, Crystal, and others, to the Reporting Services
architecture. I receive constant requests to conduct strategy sessions about
these conversions with large organizations in a diverse range of industries –
the interest grows daily as awareness of the solution becomes pervasive. Indeed,
the five- to six-plus figures that many can shave from their annual IT budgets
represent a compelling sweetener to examining this incredible toolset.

Note: To follow along with the steps we
undertake within the articles of this series, the following components, samples
and tools are recommended, and should be installed / accessible, according to
the respective documentation that accompanies MSSQL Server 2005:

Server Requirements

  • Microsoft SQL
    Server 2005 Reporting Services

  • Microsoft SQL
    Server 2005 Database Services

About the Mastering OLAP Reporting Articles …

One of
the first things that become clear to "early adopters" of Reporting
is that the "knowledgebase" for OLAP reporting with this
tool is, to say the least, sparse. As I stated in my article, Mastering OLAP
Reporting: Cascading Prompts
, the
purpose of the Mastering OLAP Reporting subset of my Reporting
series is
to focus on techniques for using Reporting Services for OLAP
reporting. In many
cases, which I try to outline in my articles at appropriate junctures, the
functionality of the reporting solutions of well-established, but expensive,
solutions, such as Cognos PowerPlay, can be met in most respects by Reporting
– at a tiny fraction of the cost.

vacuum of documentation in this arena, to date, represents a serious "undersell"
of Reporting Services, from an OLAP reporting perspective. I
hope to contribute to making this subject matter area more accessible to
everyone, and to share my implementation and conversion experiences as the
series evolves. In the meantime, rest assured that the combined relational and
OLAP reporting potential in Reporting Services will be yet another
reason that the application commoditizes business intelligence.

As I have shown in many
past articles, including Part
of this session, the Microsoft Integrated BI Solution,
consisting of the MSSQL Server 2005 Database Engine, Analysis
Services 2005
and Reporting Services 2005, provides
unprecedented flexibility in helping implementers and developers to meet client
and employer needs. My ongoing conversion of existing enterprise business
intelligence applications to the Microsoft BI solution place me in a rather
unique position to meet diverse needs with features to which my clients have
become accustomed in working within once-dominant business intelligence
applications. Reporting Services is particularly strong in the
flexibility department: Presentation nuances are legion, and one discovers,
with constant use of Reporting Services to meet a wide range of
reporting needs, how truly flexible the application can be.

As I discussed in Part
, when one is in the business of performing conversions (for
example, converting Cognos PowerPlay or Cognos Impromptu reports
to Reporting Services), and even when implementing an evolving body of
reports for the first time, the foremost challenges that we encounter are those
that arise based upon the need to replicate features that exist in
previously created reports
, quite often in tandem with a requirement to
enhance the reports to provide new capabilities and presentation options. Whether as a part of converting the reports of a
predecessor enterprise reporting system, or to meet a need to duplicate early
efforts within Reporting Services itself within enhanced reports that
offer more flexibility, additional features, and so forth (as is the scenario within
the Practice sessions of this article), we will consistently find that Reporting
not only allows the knowledgeable designer / developer to exceed
the capabilities of traditional reporting, but affords an environment within
which development can become rapid and "Edison-esque" in its "assembly-line"

In Part
, we began
the examination of a scenario
where the dynamic nature of the Reporting Services matrix data region
makes it the "object of choice" for enabling us to meet the expressed
needs of a hypothetical group of information consumers. Part of the
requirement was to replace a somewhat limited data region with a matrix
data region
that returned identical data. Creating the new matrix data
within the same .rdl file as the original matrix data
upon which it was based afforded us several advantages, both in
rapid development and in ongoing "side-by-side" contrast as we "converted"
the original data region to a new region, from which we could
launch development of the enhancements we examine in this article. Having the
two regions physically parallel made verification of comparability
between them easy, as we finished the first half of our examination by ensuring
that both regions gave us identical results.

this article, we will further evolve the matrix, which we have already
determined to be correct as a part of preparation, to meet the less intuitive
components of the business requirements of the information consumers with which
we are working. First, we will add the requested parameterization (with multivalue input
capabilities) that they have requested for Sales Territory Groups, using
a multivalue parameter. Next, we will make further structural changes
to the report, to meet their somewhat innovative business requirements for
presenting independent matrices based upon a geographical parameter
to be selected by the consumers at runtime. As is our tendency throughout the
body of our hands-on articles, we will discuss the results obtained within the development
techniques that we exploit throughout the steps of our practice exercise.
Finally, we will conclude
with a preview of the report to ascertain
the effectiveness of our solution.

In the
foregoing sections, we will continue our examination of a scenario where the
dynamic nature of the matrix helps us to meet the expressed needs of a
hypothetical group of information consumers. In this, the second half of a two-part session, we

  • Add parameterization
    (with multivalue input capabilities) for Sales Territory Groups to
    the new report, using a multivalue parameter;

  • Make structural
    changes to the report, to meet the business requirements of a hypothetical
    group of information consumers for presenting independent matrices based
    upon a geographical parameter they select at runtime;

  • Continue to incrementally
    preview the report to ascertain the effectiveness of our solution;

  • Extend the
    ongoing discussion that we began interjecting in Part One, at appropriate junctures, surrounding the results
    obtained within the development techniques that we exploit throughout our second
    practice session.

Bill entered the world of databases and financial systems when he became a consultant for CODA-Financials, a U.K. - based software company that hired only CPA's as application consultants to implement and maintain its integrated financial database - one of the most conceptually powerful, even in his current assessment, to have emerged. At CODA Bill deployed financial databases and business intelligence systems for many global clients. Working with SQL Server, Oracle, Sybase and Informix, and focusing on MSSQL Server, Bill created Island Technologies Inc. in 1997, and has developed a large and diverse customer base over the years since. Bill's background as a CPA, Internal Auditor and Management Accountant enable him to provide value to clients as a liaison between Accounting / Finance and Information Services. Moreover, as a Certified Information Technology Professional (CITP) - a Certified Public Accountant recognized for his or her unique ability to provide business insight by leveraging knowledge of information relationships and supporting technologies - Bill offers his clients the CPA's perspective and ability to understand the complicated business implications and risks associated with technology. From this perspective, he helps them to effectively manage information while ensuring the data's reliability, security, accessibility and relevance. Bill has implemented enterprise business intelligence systems over the years for many Fortune 500 companies, focusing his practice (since the advent of MSSQL Server 2000) upon the integrated Microsoft business intelligence solution. He leverages his years of experience with other enterprise OLAP and reporting applications (Cognos, Business Objects, Crystal, and others) in regular conversions of these once-dominant applications to the Microsoft BI stack. Bill believes it is easier to teach technical skills to people with non-technical training than vice-versa, and he constantly seeks ways to graft new technology into the Accounting and Finance arenas. Bill was awarded Microsoft SQL Server MVP in 2009. Hobbies include advanced literature studies and occasional lectures, with recent concentration upon the works of William Faulkner, Henry James, Marcel Proust, James Joyce, Honoré de Balzac, and Charles Dickens. Other long-time interests have included the exploration of generative music sourced from database architecture.
