The abstraction builds on a known data model with slowly changing dimensions.
") Apache Airflow , for example, is not an ETLtool per se but it helps to organize our ETL pipelines into a nice visualization of dependency graphs (DAGs) to describe the relationships between tasks. There are many other tools with more specific applications, i.e. extracting data from web pages (PyQuery, BeautifulSoup, etc.)
ETLTools: Extract, Transfer, and Load (ETL) pulls data from numerous sources and applies specific rules on the data sets as per the business requirements. You should have an understanding of the process and the tools. You should also look to master at least one programminglanguage.
For example: While Terraform is a declarative configuration language that just describes how the infrastructure will look like (execution then by the Terraform-supporting Cloud Provider), Pulumi on the other hand will execute the deployment by a programminglanguage iteratively deploying the wished cloud resources (e.g.
Technical expertise: Big data engineers should be thorough in their knowledge of technical fields such as programminglanguages, such as Java and Python, database management tools like SQL, frameworks like Hadoop, and machine learning. It is often said that big data engineers should have both depth and width in their knowledge.

It is often said that big data engineers should have both depth and width in their knowledge.
Python Python is one of the most looked upon and popular programminglanguages, using which data engineers can create integrations, data pipelines, integrations, automation, and data cleansing and analysis. They are required to work on the following: ETLtools and pipelines and Big data using tools such as Hadoop, Kafka, etc.
ETLTools – The best way to make sure that data stays high-quality is to inspect it as early as possible. You’ll need to know SQL, and a good programminglanguage for analysis, like Python or R. They can move up to roles like Data Governance Lead, Data Quality Manager, or even Chief Data Officer (CDO).
Such specialists use Python and programminglanguages for statistical analysis like R and SAS. Experience in programminglanguages. Apart from SQL, it is a big plus for such a specialist to know more advanced “data” languages like R and Python to handle various data orchestration tasks.
