Personal Career & Learning Guide for Data Analyst, Data Engineer and Data Scientist

Data Joining in Tableau is a process of combining data from two or more sources into a single view. The data sources can be of the same or different types, such as spreadsheets, databases, or cloud applications. Data joining is a crucial step in the data analysis process as it allows you to combine data from multiple sources to provide a complete and accurate picture of your data.

In Tableau, there are two main types of data joining: Inner join and Outer join. An Inner join returns only the rows that have matching values in both tables, while an Outer join returns all the rows from one table and the matching rows from the other table. There are also Left and Right Outer joins, which return all the rows from one table and the matching rows from the other.

To join data in Tableau, you first need to connect to your data sources and add them to your workbook. Once your data is in Tableau, you can join the data by right-clicking on the first data source and selecting “Join Data”. You will then be able to choose the type of join you want to perform, specify the conditions for joining the data, and select the fields you want to include in your joined data set.

Once the data is joined, you can then create visualizations and perform analysis on your joined data. This allows you to easily compare and contrast data from multiple sources and gain a deeper understanding of your data.

Joining data in Tableau is a straightforward process and can be done with just a few clicks. Whether you are working with data from spreadsheets, databases, or cloud applications, Tableau provides a powerful and intuitive tool for joining data and performing data analysis. Whether you are a beginner or an experienced data analyst, Tableau can help you gain new insights and better understand your data.
