Q #1: What is the trend of cash inflow of each seat type over the years from 2009 to 2090?





Here in these dashboards, I analysed the pattern of cash inflow through various types of contributions and receipts, for each type of seat as well as party affiliations in different states. In these graphs I read the following figures:
  • Total Cash Inflow of Incumbent Seats was the highest i.e. $1,680,060,233/-
  • Total Cash Inflow of Challenger Seats was the second highest i.e. $911,595,331/-
  • Total Cash Inflow of Open Seats was the third highest i.e. $816,630,743/-

Introduction to Dashboards


What is Dashboard?

The term dashboard originates from the automobile dashboard where drivers monitor the major functions at a glance via the instrument cluster. Dashboards give signs about a business letting you know something is wrong or something is right. The corporate world has tried for years to come up with a solution that would tell them if their business needed maintenance or if the temperature of their business was running above normal. So for businesses, we can define dashboard as:

 “A dashboard is a visual display of the most important information needed to achieve one or more objectives which fits entirely on a single computer screen so it can be monitored at a glance.”

What is the Role of Dashboards in Business Intelligence?

Dashboard is an essential constituent of business intelligence (BI). A dashboard is one of the vital ways that data is represented visually. Dashboards show key performance indicators (KPIs) in one place, so that you can see the trends, patterns and relationships that define your business. A KPI can be visualized as a simple number, chart, meter, map or other type of visual that shows you your situation of choice.

How can Dashboard help with Big Data?

There are zettabytes of data in the world today, and companies are drowning in information. A dashboard places the data the companies need in a visual, easy-to-understand format. The ability to see the data that you need, when you need it, gives you the ability to quickly understand your company’s situation at any given point in time. Rather than digging through emails and Excel spreadsheet, you can consult your dashboard for a quick insight.

How is Dashboard Useful in Business?

By using a dashboard, you can more easily process the meaning of the information your BI system is giving you, and make better decisions as a result. Everyone from the CEO to middle managers can use dashboards to see information when they need it. As a result, these workers can make changes in real time, rather than using guesswork or monthly reports.


Dashboards may be used by different users; such as front-line workers to monitor inventory, by middle managers to analyze lagging measures, and by executive managers to evaluate strategic performance against objectives. So we can say that Dashboards in combination of visual and functional features help improve understanding, awareness, and interpretation of big business data.
