Lucian Comanescu


Profile BI/Cognos Consultant



Overview


Working in a Cognos Competence Center


I was working, in the last seven years, in two Cognos Competence Center for two big banks (the
Risk Intelligence Infrastructure (RII) department of WestLB and Release Clus
ter DWH/BI at
Commerzbank), being responsible for the development, maintenance and deployment of Business
Intelligence Solutions for several risk management projects, covering different aspects of Risk
Management and Reporting for the whole bank, integrati
on of 3rd parties solutions and/or
applications into the reporting landscape (ex. DataNet, JasperReports, cocoon) and developing
and maintaining different inter
-
project interfaces.



Cognos Know
-
how and the Diversity of Cognos Roles


The biggest advantage
of working in different projects is, of course, the diversity of roles I had to
cover in the same time:



consumer, using the IBM Cognos Connection Portal to view personal reports, for business
support, and/or on behalf of the users



business support: build s
imple queries to focus on variances, shift through large amounts of
data, and investigate different areas of business through interactive analyses, ad hoc reports
and/or data extracts



report author: build sophisticated reports for consumers by gathering re
port requirements and
creating the reports for distribution



developer of SDK applications, Cognos script and Decision Stream scripting language



designer/architect: responsible for developing databases (data marts), designing relational and
multidimensional

Framework Manager models, modeling metadata and creating OLAP models



trainer: concept, materials and user trainings in Düsseldorf and London



administrator: manage the deployment of IBM Cognos 8 Business Intelligence, including
installation, configuration,

maintenance, content management, security and system
optimization



Business Knowledge and Support


My former education and all the years of experience of working close with the business
department, have developed a very good business basis
-

not only tha
t I am able to understand
and communicate effectively with business users, but also developed an interest and
understanding for the business processes themselves. I have a very good experience in gathering
business requirements and translating them into te
chnical specifications, negotiating and modifying
those requirements to match the development/IT or company strategy, evaluate the costs and
implications of different alternatives into the IT or business processes and/or evaluate the effects of
different s
olutions into the general IT landscape (how changes in a certain projects will affect other
projects or the interfaces to other projects). And I take my permanent invitation to the most
important reorganization, planning and regular business meetings as a
confirmation of the above.


This very good understanding of business logic and knowledge of pre and post systems coupled
with good knowledge of Java, C++ and PL/SQL allow me to easily and effectively trace and find
implementations problems, answer business

questions and solve different data quality issues from
the front
-
office systems, through data warehouse and risk engines, to the reporting data marts.
These analysis and investigation skills were quickly recognized and are, probably, one of the main
reaso
ns for my long lasting relationship with WestLB and I consider it a big advantage compared
with other candidates.

Profile BI/Cognos Consultant





Cognos Related Knowledge and Second Level Support


Another strong point I have is my excellent knowledge of "around" Cognos technologies
:



My excellent SQL and PL/SQL knowledge allow me to quickly analyze the performance of
different modeling options and/or report designs, via exported SQL, directly in database or,
based on an optimized SQL to change the model or report for better performan
ce. My
database knowledge was also highly appreciated during test phases (compare reports results
with data extracted directly from database), for support (mainly tracing and finding
implementation problems or data quality issues) and for ad
-
hoc reports an
d data extracts (non
-
standard time series or data requests that had to be extracted directly from database).



The years of experience as java developer not only that allowed me to easily understand and
use the Cognos SDK, but also understand the Cognos inte
rnal processes and sometimes to
find workarounds. Worth mentioning are at least Web Services and SOA architecture,
database connectivity (JDBC), java logging and related technologies like HTTP protocol, HTML
and java script, experience with Apache Web Serv
er and Tomcat.



I also have very good experience with XML and related technologies (XSLT, XPath, XQuery,
Web Services)
-

my automated xslt tool for package/reports extraction and documentation
being quickly generalized to all Cognos projects.



Another Cognos

related area were I can provide an excellent expertise is Security and LDAP:
from the protocol itself to query, design (schema, hierarchy), architecture and topology (with
replication), installation and configuration, administration, ldap java APIs (Netsc
ape, jldap,
JNDI), ldap clients, ldap servers: Netscape/iPlanet/SunOne/Sun DS, OpenLDAP, Active
Directory, different SSO strategy and Trusted Signon Provider and Cognos Namespace
implementation. The fact that I was member of the security redesign team, org
anized by
WestLB User Management, having different presentations and discussing different alternative
strategies, is a proof of those knowledge and skills.



And I cannot close this point without mentioning my UNIX, Linux and Windows skills: from
administrat
ion and tools to excellent scripting skills. My cube generations scripts and RII Queue
were highly recognized and appreciated by my current customer.



One of my best Achievements


A very challenging task was PoRiDa redesign: after less than two years of p
roject life, with
performance problems, in September 2006 I was appointed as member (of a three men team) of
the task force for the project redesign. The expectations were small, but the results overwhelming.
We completely redesign the database schema and
the Framework model, creating a very
performant multi
-
star schema with the minimum needed indexing strategy
-

only exactly those
needed for reporting, completely removed the materialized views, consolidate the portfolio
hierarchy, automatically generated t
he most important (most used) reports
-

introducing reports
burst and other improvements that leaded to improving the ETL
-
Process with almost 40% (under 3
hours), report execution times from 15 to less than 2 minutes, cube generation times from 8 to 2
hour
s. This not only that allowed online analysis (the generation of the original cubes was stopped,
cubes being generated too late), but offered also a dramatically improved user experience:



cube browse time decrease drastically because, using a cube group, w
as possible to generate
6 smaller cubes, one for each KRI (Key Risk Indicator) group with drill through from one cube
to another and to the master cube;



very fast drill through reports for detailed information, already pre
-
filtered with the cube
selection
(and database indexes following very tight this selection);



ready for download reports: pre
-
generated standard reports (bursted per portfolio groups) and
scheduled data extracts



faster report execution due to a parameter map with portfolio version id and r
un id (the
database partitions keys)

Personal skills


I was also very appreciated, at WestLB, for my interest in the internal processes and my ideas and
contributions to improve those processes. The Cognos Cockpit, Package Documentation Tool and
RII Qu
eue were some of the most remarkable improvements. My open personality and
communication abilities help me develop excellent relationships with colleagues, peers from other
projects, business users and production support team as well as with team and depar
tment
leaders. My excellent analytic skills and abilities to locate problems determined lots of colleagues
and peers to ask my help in solving problems. Because of my abilities to learn quickly and digest
new things, I was almost always selected to test ne
w Cognos versions, check their features and
evaluate their usefulness for my client and take part into several research groups and task forces.



Summary


Probably the main gain of working in multiple projects is the exposure to different aspects of
busine
ss, different project requirements and targets and different types of problems I had to solve
during different points in the projects' life cycles. Each project had its own set of different user and
technical requirements, different targets and constraints
, different types of day
-
to
-
day problems and
support issues. All those, together with my knowledge and experience with the main Cognos
Products, databases and SQL, Security and LDAP, UNIX and shell scripting, Cognos scripting,
java and XML and my personal
skills and abilities will allow me to easily integrate into your projects
and teams and quickly become effective.

y

Administrative web pages (add

on to Cognos Connection), based on a collection of
different SDK servlets, to perform administrative tasks in a very convenient way. The most
used functionality was: remove reports output, change cube and cube views gateways

(before or after deployment), list the content store based on different filters (like package,
user role/group, views on a selected cube/report), change folders access permissions (e.g.
add a new user group to a folder and all subfolders that do not inher
it parent's permissions
or replace one user role/group with another).


I have also developed a set of scripts (based on Cognos SDK) to trigger jobs and/or
reports from shell scripts and allow the integration of Cognos reports into the scheduling
system of
the bank (RII
-
Queue and Control
-
M).



Main Responsibilities

Project Summary

Customer authentication and authorization solution for the Common Data warehouse
Plat
form (future unique bank wide Cognos platform). CDP was the first project that moved
away from the Cognos Series 7 Namespace, using the company standard Active Directory
infrastructure. Due to the large number of users and groups in the 4 separate Active
D
irectory servers, the performance on Cognos was very poor. My solution was a
replication tool to replicate only CDP relevant users and groups and implementation of a
custom Java Trusted Signon Provider that authenticate the users against the master Active
Directory, but uses, for authorization, the lighter OpenLDAP replica.



Main Responsibilities
