insight.”

Business Intelligence?

• The term Business Intelligence (BI) represents the tools and systems that play a key role in the strategic planning process of the corporation. These systems allow a company to gather, store, access and analyse corporate data to aid in decision-making.

• Basically Business Intelligence (BI) is the transformation of raw data into meaningful and useful information for business analysis purposes. BI can handle enormous amounts of unstructured data to help identify, develop and otherwise create new strategic business opportunities.

• The most important thing that we need for BI is, a vast knowledge of data warehouse or we can say data mining. Because here everything is based on Big Data concept.

• it’s most important to know how to cluster the data and organize the data in a manner so that we can get some useful insights which are actionable.

Acquisition (Collection of data

from various sources)

Marshaling (Assemble, sorting and

storing of data to be available for analysis)

Analysis (Finding business

opportunities or insights from data)

Action (Building the output of the new analysis back

into new optimized business processes)

How actually we are moving

About PowerPivot

PowerPivot is the most important tool that is used for BI in Excel. Microsoft PowerPivot is an add-in for Microsoft Excel 2010 that enables you to import millions of rows of data from multiple data sources into a single Excel workbook.

Features/Support by PowerPivot:

• We can add data from multiple data sources.• We can create relationships between heterogeneous data.• We can create calculated columns.• Measure using formulas.• We can build PivotTables and Pivot Charts.• We can analyze the data so that you can make timely business decisions.

Add data from various sources

As with any Excel workbook, in PowerPivot for Excel you can add data from a wide variety of data sources, including a relational database, a multidimensional database, data feeds, an Excel table, or a Reporting Services report. You can also add data from files on your local computer, and use data that you download from the Web.

PowerPivot enables you to add and work with millions of rows of data locally, depending on the actual physical memory available on your desktop computer.

We can add data in two manner.• Using import wizard• Using copy & paste.

Create Relationships between Tables

• PowerPivot is used to view and create relationships between data from different data sources.

• A relationship is a connection between two tables of data that establishes how the data in the two tables should be correlated.

Why Create Relationships?

In order to perform any meaningful analysis, your data sources must have relationships between them. More specifically, relationships enable you to:

• Filter data in one table by columns of data from related tables.• Integrate columns from multiple tables into a PivotTable or PivotChart.• Easily look up values in related tables using Data Analysis Expressions (DAX)

formulas.

We can create relationship b/w tables in following way:

• By manually joining tables in the PowerPivot window or columns in Diagram View.• automatically if PowerPivot for Excel detects existing relationships.

One of the limitations in the initial release of PowerPivot for Excel concerns relationships between tables. At this time, PowerPivot for Excel only supports one-to-one and one-to-many relationships between tables.

Create a Calculated Column

A calculated column is based on data that already exists in your PowerPivot workbook. We can add calculated column in given way.

• In the PowerPivot window, switch back to Data View, and then select the table.• On the Design tab, in the Columns group, click Add.• In the formula bar above the table, type the following formula. AutoComplete

helps you type the fully qualified names of columns and tables, and lists the functions that are available. e.g. =[SalesAmount] - [TotalCost] - [ReturnAmount].

• When you have finished building the formula, press ENTER to accept the formula.

Create a PivotTable and PivotChart from PowerPivot Data

• Once you've added data to your PowerPivot workbook, PivotTables help you efficiently analyze your data in detail. You can make comparisons, detect patterns and relationships, and discover trends.

Analyzing the data

Once we have the PivotTable and PivotChart for corresponding data than we can analyze the things in better way.
