Learn how to become a Big Data Engineer from Intellipaat:
Introduction to Big Data Engineering?
One has to think about engineering as associated with designing and building things. The key concept of the domain lies in that. However, in this case, it involves the designing and building of pipelines for the transformation and transportation of data into a usable state to be used by Data Scientists and other end-users.
The pipelines aid in gathering data into a single warehouse from disparate sources. Data Engineering does not involve experimental design but focuses more on the development of systems for easier flow and information access.

Who is a Big Data Engineer?
Data generation is of no use unless processed and analyzed with competence. Professionals in the field of Big Data are responsible for undertaking this arduous task. Big Data Engineers develop, test, and evaluate the Big Data infrastructure of a company for making the data fit for analyses, which in turn brings in growth for the company.
What is the difference between Data Engineer and Data Scientist?
Both Data Scientist and Big Data Engineer are critical roles in an advanced analytics team. For Data Science to be meaningful and effective, the support of Big Data Engineers should not be neglected. Although the knowledge of tools and the priority skills are different, frequent collaborations are often seen between Data Scientists and Data Engineers.
Data Scientists deal with the advanced analytics of data generated and stored in databases. On the other hand, Data Engineers are responsible for the design, optimization, and management of the data flow among those databases. Evidently, Data Scientists will need to be highly skilled in statistics, math, R programming, Machine Learning algorithms, and techniques. Likewise, Data Engineers will need to be well-versed in SQL, NoSQL, MySQL, cloud technologies and architecture, and frameworks such as Agile and Scrum.

What are the job responsibilities of a data engineer?
Let’s discuss the responsibilities of a Data Engineer in detail:
- Design and implementation of software systems, along with their verification and maintenance
- Development of robust systems for the purpose of ingestion and data processing
- ETL (Extract, Transform, and Load) process and operations
- Data quality improvement through research on various new methods
- Building data architectures to meet business requirements
- Generation of structured solutions through the integration of programming languages and tools
- Data mining from disparate sources for the development of efficient business models
- Collaboration with Data Analysts, Data Scientists, and other teams.
Above are only a few of the key responsibilities of a Big Data Engineer. Next, we will take a look at the skill sets that are crucial in carrying out these responsibilities.
Steps to Become a Data Engineer?
One does not necessarily require a background in computer science to enter this domain. People from diverse backgrounds can be seen in this field but with a set of skills. Here are some of the skills that can get you into the field of Big Data Engineering.
They are one of the fundamental concepts of Big Data Engineering. Algorithms are, basically, instructions that enable a sequence of actions to be performed in a certain order. They can be used regardless of the programming language used. Algorithms are used to find, insert, sort, or delete items in a database.
Data handling requires an efficient order for easier access. Data structures (or databases) aid in better management of data by organizing it well. Some different data structures are array, binary tree, matrix, graph, etc. One can later move from basic data structures to abstract data structures.
SQL (Structured Query Language) is one of the most popular programming languages in the world of Big Data and has been in the market for a long time. It is primarily used for the generation of queries from a client program to the database. Simply put, it allows for the editing and storage of data on database servers.

Python is widely used for its versatility, and it is easy to work with. It is a must-have skill for every data enthusiast. There is a Python library for every task that needs to be performed. Along with Python, Scala and Java are equally important skill sets that are crucial to Big Data Engineers as tools such as Hadoop, Apache Spark, Apache Kafka, HBase, and others mostly use these languages. Learning these programming languages will enable one to use these Big Data tools without difficulty.
Big Data Tools
Apache Hadoop, Spark, and Kafka are some of the popular Big Data tools. They are vital in making data management and storage easier and more straightforward. For instance, Hadoop is used to come up with solutions to problems related to huge amounts of data. Spark provides an interface for programming clusters. Big Data Engineers will need to get familiar with more tools as they progress further into the field.

This includes Software Architect and Software Engineer skills. Data is stored in clusters that operate independently. Big Data Engineers need to have a good knowledge of data clusters and their systems, including the number of problems faced by these data clusters and how to come up with the right solutions.
Data pipelines are software solutions that build pathways for the flow of data. They help to do away with several manual steps from the process of data transfer. Aside from data warehouses, data pipelines can be implemented to transfer data to applications too. Data Engineers spend a considerable amount of time in the building and management of data pipelines.
Data modeling skills are very essential for Data Engineers as they are required to understand where to normalize and denormalize data in the warehouse, how to structure tables and partitions, how to retrieve certain attributes, etc.
Above are the skills required for a Big Data Engineer to have a strong command of the domain. Apart from these, they should also be proficient in analytics, data mining, ETL, cloud platforms, automation, etc.
