Understanding Data Drill Down And Drill Through Analysis And Their Role In Efficient Reporting

An introduction to drill through and drill down reports by datapine

It is no secret that the business world is becoming more data-driven by the minute. Every day, more and more decision-makers rely on data coming from multiple sources to make informed strategic decisions. But, as the use of data becomes more popular the amount of information being collected is growing exponentially. 

With this thought in mind, BI tools develop multiple solutions to assist businesses in dealing with their information in the most efficient way possible. From automated reporting, predictive analytics, and interactive data visualizations, reporting on data has never been easier. 

Now, if you are just getting started with data analysis and business intelligence it is important that you are informed about the most efficient ways to manage your data. In this post, we will go through two relevant business intelligence features and how they can bring value to your reporting process. We are talking about drill downs and drill through. 

Let’s kick it off with a detailed drill down meaning!

What Is A Drill Down?

Drill down is an analytical practice that allows you to visualize granular levels of data in one chart. By “nesting” additional variables of hierarchical data, drill down analysis lets you extract deeper insights without jumping to another chart or report. 

In general, data drills can be added to any chart or data visualization. However, they prove to be specifically useful in tables as they allow you to access additional data to extract deeper insights. For example, breaking down clients by continent, country, and city. Unlike other chart types, tables can especially benefit from drill downs due to the fact that bigger data sets can be compressed without overcrowding the chart. 

The main value of drilling down on data is the fact that it lets you dig through hierarchical information in an interactive way without the need to create an extra report or overcrowd your current report with dozens of charts. Like this, you can spot valuable insights on the go all in one place. 

Example of a drill down from a management report

The image above shows a drill down report for management. The chart highlighted in green is showing the active customers by country. A data drill here would let you click on this chart to get a lower level of the x-axis like the active users by city. The image below shows the lower level of the data after the drilling is applied.

What Is Drill Through?

A drill through is an analytical feature that allows you to visualize additional, more detailed information about a specific KPI in a report. The difference with a drill down is that in a drill though report the new data is opened in a pop-up and not on the same chart. 

Drill through analysis is often confused with drill down analysis as both practices are very similar. But, as we just mentioned, there is one main factor that makes them different. While drilling down provides granular information within a specific chart or data set, drill throughs display another aspect of the data that might be relevant and it does it by opening a pop-up chart.

For example, the image above shows a management dashboard with 5 number charts on the top. While it is important to know the status of these metrics, by themselves they don’t provide as much information. However, when you click on them, a drill through would allow you to get extra details or insights about that specific metric or KPI. For instance, the net profit metric that is highlighted in the report could benefit from a drill through to see from which specific products is the profit coming from. In this case, the drill is showing a pop-up with the net profit by product category, as seen in the image below.

We will go deeper into this and other examples later in the post. But first, let’s see what is the role of data drilling in modern online reporting.  

The Role Of Data Drilling In Reporting

Drill down and drill throughs are two powerful features of BI reporting tools. Not only do they allow you to extract deeper insights from your data, but they also make the reporting process more intuitive and efficient. For instance, by using drill down reports you can find the answers to important questions such as your sales by country, on which channels your target customers buy the most, which product category is the most successful, and much more. 

And not just that, by presenting one dimension of data at a time, drill through and drill down reporting features lighten the data load making the reporting process more efficient for the end-user. Summing up to all this, they are important because: 

  • They allow for deeper insights: As mentioned, one of the main benefits of using data drilling techniques is that they allow you to extract deeper conclusions that would otherwise remain untapped. Drill through and drill down reporting can prove to be especially useful to support discussions as you can easily take complex reports and adapt them into a macro-level with just a few clicks. 
  • They save costs and time: No matter the type of report you are building, it can be a tedious and time-consuming task. With so many metrics and KPIs to track, businesses face the issue of building several reports for each area and goal. Data drill reports allow for a level of interactivity that makes it possible to visualize large volumes of data all in one place. In the long run, this will save your business time and money as there will be no need to generate infinite static reports. 
  • See data from different points of view: If you ever worked with data before, you must know that the deeper you dig the more value you will find. Drilling on data enables you to look at your most relevant information and visualize it from different points of view. Like this, you can discover the roots of different scenarios and build informed strategies that will set your business to succeed. 
  • Enhance the reporting experience: Data reporting is not an easy task. Users with no technical knowledge might struggle to go through big sets of data and extract the needed conclusions. Self-service BI tools offer intuitive data drill features that are easy to use. With just a few clicks, users from all levels of knowledge can dive into the reports and extract all the needed information in an intuitive and interactive way. Like this, the entire reporting journey will be enhanced.

Drill Down vs. Drill Through: Examples In Reporting 

By now you should be able to understand the benefits that these two interactive reporting features can bring to your business. To keep putting the value of these important analytical features into perspective let’s see each of them in action with some examples generated with dashboard software

A. Drill Down Report Examples 

Self service BI tools such as datapine offer drill down functionalities with just a few clicks. Alongside the possibility to drill into various levels, you can also choose the way you will interact with the drilled data. For example, you can choose to place a button at the top of the drilled chart to go back to the original data set easily, you can also tell the tool to hide any empty hierarchy levels so you can work only with data that has value. Let’s see some of these things in action. 

  1. Customers by country and city 

Our first example is a graph displaying the customers by country & city. As seen in the video below, the drill feature filters the entire chart to display the number of customers by each city from Australia.  We can also see how you can easily go back to check other countries by clicking on the “country” button at the top right corner. Like this, you don’t need to go into other reports or charts to go get extra insights on this data. 

Another important note is that in this example we are just showing the drill from country to city, but you can go as further as your data allows it. Here you could keep drilling down into zip codes, specific stores in each city, and even top-performing sales representatives by store. This level of detail enables you to fine-tune your strategies with all the needed information. 

  1. Customers by product category and product name

Our next example is from a table chart. As mentioned at the beginning of the post, tables are the type of online data visualization that can benefit the most from drill down analysis as they can cover several layers of data. Applying data drills to your tables can be useful as it allows you to place larger data sets into your reports without overcrowding them. 

In the drill down visualization above we can see how it is possible to break down each of the product categories and understand which specific products are attracting the most customers. This is very valuable since it allows you to instantly compare which are your customers' favorite products and draw conclusions about future investments, promotions, among other things. 

  1. Customers by channel and age

The last in our list of drill down analysis examples is a bar chart tracking the number of active customers by channel and age. Once again, here we can see how easy it is to filter the entire chart based on the specific data that you want to visualize. From interns to managers, anyone can use this chart to make relevant strategic decisions. 

Understanding the different age ranges of your customers depending on the channel can provide very valuable insights. For example, you can see which channels your target audience uses the most, or if you have a business that targets people of all ages, you can understand which channels to target each age group the best. 

B. Drill Through Report Examples 

Now that we’ve covered some insightful drill down examples it is time to get some visual examples of how drill throughs work in a real reporting environment. As mentioned, drilling through is a valuable feature that allows you to navigate your data dashboards and see useful additional data without the need to overcrowd the report. Let’s see three examples more in detail. 

  1. Profit per product category 

Coming back to our first example at the beginning of the post, this management report uses drill throughs to complement the information of relevant performance metrics. Here we can see that by clicking into the net profit a pie chart is coming up as a pop-up displaying the profit of each product category. Like this, you can understand which category is bringing the most profit and focus your attention on it. 

  1. Top 10 most sold units 

Our next example is about units sold. Keeping track of the numbers of units sold during a given time is very important, however, this metric alone doesn’t tell us more than just a number. To extract the maximum value out of it and extract actionable conclusions, this business dashboard uses a drill through to display the top 10 most sold units from all product categories. Now, with this information in hand, we can extract conclusions about the most sold units and plan production and advertising strategies accordingly. 

  1. Total revenue 

Our last example was generated with a modern BI dashboard software and it is showing a variation of a normal drill through report. In this case, since the additional data is too big to be shown in a pop-up, the drill is working as a hyperlink to another dashboard tab that is breaking down the total revenue in areas such as sales, top products, customers worldwide, and more. This is extremely useful as it allows you to jump from different sections of your reports to others as needed. After checking the needed data, you just need to go back to your original report and move on with your analysis.
