To develop an ETL solution, an ETL developer must use a different programming language to manipulate and extract data from relational databases. In this article, you will learn about the different languages that are used to develop ETL solutions. The three most popular programming languages for developing ETL solutions are SQL, Python, and Java. SQL is a popular programming language used for Expressions-based Programming (EBP) tasks such as SELECTs and UPDATEs. Python is used for common tasks such as mathematical operations and data analysis. Java is a popular language used for creating object-oriented programs and libraries. When it comes to extracting data from relational databases, there are two types of extraction methods that are commonly used: join extraction and merge extraction. Join extraction extracts all the information in one table into another table; merge extraction extracts all the information in one table into another table by merging the columns in the first table with the columns in the second table. join extraction is more common because it can be faster than merge extraction. However, join extraction can lead to incorrect results if there are many joins between tables; therefore,
