Data Analysis
The people who understand their data best are the users
of it. Working together with the users we can recommend
which BI products are the most suitable ways of viewing
your data.
Data in itself is usually not that useful until we
are able to analyse it and thereby use it to make decisions
and to give us insights into patterns and trends. Data
analysis turns raw data into meaningful information.
In Business Intelligence terms if often involves KPIs
(key performance indicators), measures and metrics.
First you decide what your measures are, then you can
build them into your metadata, either building a data
warehouse or modelling the data directly into a product
such as Cognos Framework Manager.
Measures help you analyse your data, but the data itself
is often spread out across different systems, perhaps
even different countries and even keyed directly into
different spreadsheets and flat files. By using data
warehousing techniques you can gather all this data
together so it can be effectively analysed and so add
value to your organisation.
The analysis itself can be done in a number of different
ways. For example, metrics can be viewed month-on-month
in a scorecard, KPIs can be tracked in a personalised
dashboard. Data can be summarised using dimensional
modelling, which puts it into hierarchies on which you
can drill up or down. OLAP cubes are a popular way of
presenting dimensionally modelled data.
