Most Popular Data Engineering Tools to Learn

Data engineering is a collection of operations used to create mechanisms and interfaces that allow the flow of data and the way you access information. Dedicated specialists called data engineers help maintain data so it can be available easily.

In other words, data engineers play a pivotal role in setting up the infrastructure and maintaining it. This is to ensure that the requisitedata is always available for analysts to complete their work.

What is Data Engineering?

• Data engineering is the specialized discipline of designing and creating systems that allow people to gather and evaluate raw data from various sources and in multiple formats. 
• These structures enable people discover real-world applications of the data, which companies can use to make important decisions to aid their growth. 
• This is achieved through the use of industry-leading data engineering tools that allow for the organization and storage of large volumes of data, what is also knows as big data. 

Top Data Engineering tools

• Microsoft Azure Data Engineering Tools

  Microsoft Azure provides a range of data engineering tools, including Azure Data Factory for data integration, Azure Databricks for big data analytics, and Azure Synapse Analytics for data warehousing. 

Principles and concepts of data engineering

So far, we have seen the most used data engineering tools, let’s look at the basic principles of data engineering

• Expecting that data will be of poor quality
  Data will always be in the rawest of forms. You will have to team up with data scientists to clean, process, and store it.
• Measuring the characteristics of the data
  The data that will be processed needs to be accurate, complete, and reliable. It also needs to be relevant at all times. After that, you can develop a system for that data.
• Maintain provenance of data
  The provenance of data is related to questions like why the data was produced and how it was produced, where it was produced, when it was produced, and by whom it was produced. All this information helps in understanding the source of data.
• Keep the data storage immutable
  The data storage will always be completely static and unspoiled for eternity. Immutable storage stores specific data in a form that does not tamper, unmodify or remove.
• Monitor information loss
  Data engineering platforms should also be able to inspect the loss of data during delivery. They should know what data is not there and where it was lost. This happens when data is processed in an input file. 
• Data is static
  Although extremely rare, it is easy to understand and manage static data. The solution for such data works forever. But it is just the ideal situation. In reality, data is never static. Assuming data to be static, data engineers build a system around it.  
• Data set is ELT and ETL 
  It is also known as the data pipeline. Maintaining a secure and reliable flow of data is what the data engineering job is all about. ETL is an extract-transform-load process. Here the data is extracted from the source, processed to get the necessary information, and then loaded into the storage system. ELT is an extract-load-transform process where the transformed dataset is loaded back to the database. Together they make up the data pipeline.  
• Data engineering is all about making predictions
  Data engineering uses the power of prediction in various fields. But data engineering is behind all these operations, which helps in the computation of these predictions.
• Data engineering focuses on Algorithms
  Data engineering consists of a bunch of techniques based on algorithms. It is all about training computers to carry out specific tasks. Moreover, it helps to develop data processing platforms that train computers or systems to retrieve information through logical reasoning systems.

Skills needed for a Data Engineer job

Apart from having knowledge on the data engineering tools, every data engineer must possess certain skills when working on any data engineering projects, which include: 

1. Coding
   As a Data Engineer, you are expected to know several coding languages. But which ones should you go for? There are many programming languages, but you are not expected to know all. Every programming language has a specific purpose. For data engineering, you are expected to know SQL, NoSQL, Python, Java, R, and Scala.
2. Cloud storage and data warehousing
   You should be aware of cloud storage and its capabilities. Cloud allows you to store big data. You should also know about AWS (Amazon web services) and Google cloud. 
3. Knowledge of OS
   You might know about Windows OS or macOS, but you also need to know about Linux operating systems as a data engineer. You should know all about the components of infrastructure and the architecture of your OS. Can you navigate various configurations on the local server? Do you know about Access control methods? Big Data Engineer jobs require a strong foundation in operating systems.
4. Database Systems
   As a data engineer, you must ensure that you know about SQL databases, NoSQL databases, relational databases, and cloud databases. You should also know how to store big data on storage servers. Proficient knowledge of data engineering tools is very crucial for data engineers.
5. Analysis of data
   A data engineer job also requires a thorough knowledge of various data engineering tools, such as Apache Spark, Power BI, Tableau, to name a few. 
6. Critical Thinking
   This is one of the primary requisites of becoming a data engineer. Without being able to think critically, the data engineer might not be able to chalk out a solution to a problem. 
7. Understanding the basics of Machine Learning
   A Data Engineer is also expected to know the foundational principles of machine learning. They need to understand these concepts to develop machine learning platforms. 
8. Communication skills
   For a data engineering job, you are required to work with several stakeholders, which warrants strong communication skills. You should be able to communicate your ideas effectively and clearly.

If big data interests you, you may consider data engineering as a career option. If you want to learn about data engineering online, you can enroll in the Certificate Program in Data Engineering from Hero Vired.
