Exploring data is an integral part of any data analysis project. Microsoft Fabric is a game changer as it provides various tools for data exploration and preparation. Notebooks, in particular, have been found to be one of the fastest ways for initiating data exploration. Inspiration is drawn from the world of experiment, exploration, and the integration into the Fabric data science.
A deep dive is taken into the details of how to read data from Azure Data Lake Storage using shortcuts and thus, capitalize on the Onelake flexibility. Organizing raw data into structured tables serves as a fundamental step for basic data exploration. Data from the diverse and enchanting city of London is used in this exploration, highlighting the accessibility and versatility that Fabric offers for data analysis.
For the primary example, an Azure Data Lake Storage (ADLS) account is connected by a shortcut to a workspace in the system, named "Workspace 1". The aim is to replicate that data from ADLS to a new workspace known as "Workspace 2". This is facilitated by the Onelake that sits between the two workspaces. Additional reading can be found here.
Data manipulation is crucial to restructure, copy, or modify data to meet specific requirements. Incorporation of several techniques in data manipulation leads to a more effective data exploration process. Fabric, known for its versatility, provides several ways of performing this task.
One way is through the mssparkutils tool which is a preferred choice among many users. It allows recursive exploration of subfolders within the main folder, copying the data while still maintaining the same structure at the destination. A block written in Python demonstrates this functionality and the ease with which it is implemented.
Once the data is copied and organized into delta tables, the next step is to make use of it. The data is then scrutinized to understand different factors using pivot tables and pie charts, which give a more significant visual representation of the data and insights.
For instance, looking specifically at music events in London, statistical items such as standard deviation, the mean, the minimum, and maximum are determined. These serve to measure the variability of data points relative to the average. This enhances our knowledge on variation in music events across different London wards.
Ultimately, this blog post does not only illustrate the functionalities Microsoft Fabric provides, but also the adaptability of these tools in various data operations. From data extraction, transformation to data exploration, the Fabric comes packed with interactive and user-friendly resources that can suit individual project demands.

The Microsoft Fabric program offers an exciting array of tools for data analysis. Its fast-paced world of exploration and integration makes it a perfect fit for data enthusiasts who want to administrate their data effectively.
To better understand Microsoft Fabric, we would take a close look at Microsoft Azure Data Lake Storage. Here, we learn how to read data, use shortcuts, and structure raw data into tables using Onelake's flexibility. This foundational knowledge is crucial in mastering data analysis within Microsoft Fabric.
Ever wondered how to unlock the massive potential of a data Lakehouse? Here, we illustrate how an ADLS account connects via a shortcut to a workspace in Fabric. The goal is to copy data from ADLS to a new workspace using Onelake, making data migration seamless within workspaces.
If you're curious about the other ways to achieve this, you'll find the Microsoft Spark utilities interesting. It allows you to do a recursive search of subfolders inside the main folder, including copying and creating directories.
Once this data copy is complete, we delve into CSV data, reading it and saving it as delta tables inside the Lakehouse using similar folder structures. Afterwards, we explore implements such as Z-order optimization and V-order at the Lakehouse Level to get the best out of our data.
Tables created, we proceed to look at the data. For instance, taking a hundred "Wards" (the neighborhood unit that organizes the data), we can explore the variability of data points close to the average. Using measures like minimum values, maximum values, mean, and standard deviation helps us understand the spread of music events across London.
By plotting Histograms, calculating for outliers, and looking at frequency distribution, you can grasp an overview of music events across Ward. This helps spot areas with unusual event counts and get an understanding of the variability of music events across "Wards"
In summary, Microsoft Fabric makes it simple to copy data from an ADLS shortcut - Workspace1 to Workspace 2, through the Onelake structure. After the data is set in place, we apply the same recursive logic to create delta tables from the CSV files and begin with some basic data exploration.
By the end of this journey, you should have a clearer understanding of how you can make the most out of Microsoft Fabric for more effective data analysis.
