The business itelligence project

• A new reporting system for the wastewater process

• including all relevant plants• including business data• including Laboratory data• easy to use (one click),

scalable, no client administration, intranet application, etc. ...


BI - the requirement

• Different systems for data storage

• Different security concepts• Different isolated reporting

solutions • Every new report leads to

stress of the operative staff

• One Database for the storage of relevant data

• One security concept• One reporting solution• independent from

operative systems

Requests to the reporting tool

• Drill, e.g. drill through monthly reports• filter by location, e.g. treatment plant or effluent • calculate new data, e.g. load = flow(PI Data) *

concentration (LIMS Data)• monthly broadcasting of reports (*.pdf-format)• user specific profiles and security related to the

report• prompting


The decision

• Consolidation of process data with PI, this means to build up the PI System in all plants

• Build up an ETL process

• „Business Objects“ as reporting tool

Business Intelligence


Query, Reporting, and Analysis


BusinessObjects• Easy to use

– Single interface for query, reporting, and analysis

– Use your own business terms

– Drag and drop report creation

• Powerful

– Powerful one-click functions (pivot, variance, ranking, alerts)

– Multiple data sources (DW, ERP, OLAP, Excel, internet…)

– Highly customizable through open object model

• Deployable

– “Zero admin” (self-install & update, no client middleware)

– C/S or 3-tier web mode with component-based architecture


BusinessObjects C/S

Mix tables, graphics, and charts

Several reports in one document

Toolbar functions


Web-mode

Reformat chart with a single click

Create new documents from within the browser

Drill directly on charts and tables

Save and publish documents


Portal and Broadcasting


BusinessObjects InfoView

• A centralized point for all BI information

– Including non-Business Objects documents

• Personalized interface

– Users can define their own environment

• Fully integrated into the BusinessObjects suite

– Leverages the WebIntelligence infrastructure

– Shares the Business Objects repository

• Also a BI content provider to EIPs

– Partnerships with major Enterprise Information Portal vendors


InfoView

Favorite report

Multiple document types

Excel, or other file


Broadcast Agent

Access multiple data sources

Distribute to multiple device types

Serve web and Windows users


Administration


BusinessObjects Designer

• Universe creation– In a few mouse clicks

• Leverage existing metadata

– Dynamic access to Informatica, Ardent, and others

– Universe linking• Exploit DW power

– Aggregate awareness


Supervisor Protect information resources

Data access (row-level) Resource utilization Product functions

Streamline user administration User profile inheritance Nested groups of users Reuse NT authentication

Maintain resources easily Central repository

The result

Pretty nice, but ....

can I trust the results ?and what is that ?


Connecting BI to PI directly

• Action of the user causes in uncontrolled SQL-statements

• It is possible to shut down the PI SQL Server by „select * from *“-statement

• Data are not validated
