Hands-On Data Warehousing with Azure Data Factory

By: Christian Cote, Michelle Gutzait, Giuseppe Ciaburro

Overview of this book

ETL is one of the essential techniques in data processing. Given data is everywhere, ETL will always be the vital process to handle data from different sources. Hands-On Data Warehousing with Azure Data Factory starts with the basic concepts of data warehousing and ETL process. You will learn how Azure Data Factory and SSIS can be used to understand the key components of an ETL solution. You will go through different services offered by Azure that can be used by ADF and SSIS, such as Azure Data Lake Analytics, Machine Learning and Databrick’s Spark with the help of practical examples. You will explore how to design and implement ETL hybrid solutions using different integration services with a step-by-step approach. Once you get to grips with all this, you will use Power BI to interact with data coming from different sources in order to reveal valuable insights. By the end of this book, you will not only learn how to build your own ETL solutions but also address the key challenges that are faced while building them.

Breast cancer detection


The breast is made up of a set of glands and adipose tissue, and is placed between the skin and the chest wall. In fact, it is not a single gland but a set of glandular structures, called lobules, joined together to form a lobe. In a breast, there are 15 to 20 lobes. The milk reaches the nipple from the lobules through small tubes called milk ducts.

Breast cancer is a potentially serious disease if it is not detected and treated for a long time. It is caused by uncontrolled multiplication of some cells in the mammary gland that are transformed into malignant cells. This means that they have the ability to detach themselves from the tissue that has generated them to invade the surrounding tissues and eventually other organs of the body. In theory, cancers can be formed from all types of breast tissues, but the most common ones are from glandular cells or from those forming the walls of the ducts.

The objective of this example is to identify each of a number of benign...
