There's nothing more valuable than data —and that's true. According to the World Economic Forum, the world's global data was worth more than $3 trillion in 2017, an amount that has grown steadily over the past five years.
Data engineers, in this case, are one of the key players in building and designing the system to collect, store, and analyze bid data that is—of course—important for every industry.
In simple words, data engineering is the process of creating and maintaining systems that collect, store, and analyze large-scale data. As we all know, data is a key thing that has relevance for almost every sector, no matter how small or large.
Organizations worldwide have huge amounts of data, and they require the right people and technology to ensure it is in good shape for data scientists and analysts to use.
What is a data engineer?
A data engineer is an IT professional who prepares data for analysis or operation. These software engineers are mainly in charge of building data pipelines that connect information from different sources. They merge, clean and structure data for analytics applications. They make data more accessible and improve their organization’s big data ecosystem.
The amount of data an engineer handles depends on the organization's size. The larger the company, the more complex the analytics architecture and the more data the engineer will handle.
Some industries have more data-intensive needs, like healthcare, retail and financial services. On the other hand, data engineers collaborate with data science teams, enhancing data transparency and enabling businesses to make more reliable business decisions.
What does a data engineer do?
Data engineers build the foundation of a database and its architecture. They evaluate various requirements and apply suitable database techniques to create a solid architecture. Then, the data engineer starts the implementation process and develops the database from the ground up.
Data engineersengineers also perform regular testing to detect bugs or performance issues. A data engineer is responsible for maintaining the database and ensuring that it runs smoothly without any disruption. When a database fails, it affects the related IT infrastructure.
The expertise of a data engineer is especially needed to manage large-scale processing systems where performance and scalability issues need constant maintenance.
Data engineers can also assist the data science team by creating dataset procedures to help with data mining, modeling, and production. In this way, their role is essential in improving data quality.
Roles and responsibilities of a data engineer:
- Import data from RDBMS to HDFS using SQOOP for data reliability.
- Automat test, analysis, plotting and reporting with Python scripts.
- Use Linux shell scripts to automate the build process and file transfers between hosts.
- Develop SAS programs to automate manual testing procedures and increase audit efficiency.
- Manage warehousing operations and parallel processing with the Teradata database system.
- Configured and managed the JobScope ERP system for make-to-order/make-to-stock design and manufacturing.
- Develop SSRS reports for SSAS database documentation and data warehouse data dictionary.
- Use Java scripts, CSS, and HTML for web pages.
- Program core Java application with Eclipse IDE.
- Use DataFrame API in Scala to convert distributed data into named columns.
- Import and export data into HDFS and RDBMS using SQOOP.
- Develop SSAS multidimensional cubes from the data warehouse.
- Define OOZIE job flows.
- Connect to the database with SQOOP.
- Use Eclipse as IDE for development.
Why should you pursue a data engineering career?
If you are looking for a fulfilling and challenging career, you must consider data engineering. As a data engineer, you will play an important role in your organization’s success, making data more accessible and useful for data scientists, analysts, and decision-makers.
To succeed in this career, you will use your programming and problem-solving skills to create solutions that can handle large amounts of data.
And there is no doubt that data is becoming a lifeblood for every organization in the world. As an Indian citizen, you must know that the Indian government supports the Digital India program to boost digital development.
As data plays a crucial role in many industries, the demand for professionals who can understand, manage, and analyze data will likely increase.
How to become a successful data engineer?
Many data engineers have computer science, information technology, or applied math backgrounds. A formal degree, such as from a university or college, can help you develop the math and data skills you need to deal with complex tasks in this rapidly changing field.
You can also pursue a postgraduate degree to improve your career and make more money. Apart from earning a degree, there are a few other things you can consider to achieve your goals.
Online degree program:
To become a data engineer, your first move can be to earn an online degree. There are many bachelor’s online degrees, such as mathematics, computer science, physics or engineering, that you can take into consideration.
Apart from the bachelor's degree program, you can enroll in a master’s degree program such as computer science or computer engineering.
Coding: You need to be good at coding languages for this role. Some common programming languages you must be good at are SQL, NoSQL, Python, Java, R, and Scala.
Relational and non-relational databases: Databases are one of the most common solutions for data storage. You should know both relational and non-relational databases and how they work.
ETL (extract, transform, and load) systems: ETL moves data from databases and other sources into a single repository, like a data warehouse. Some common ETL tools are Xplenty, Stitch, Alooma, and Talend.
Data storage: Data storage is another important skill. Working as a data engineer, you should keep in mind that some types of data should be stored differently. As you design data solutions for your organization, you’ll need to know when to use a data lake versus a data warehouse.
Automation and scripting: Automation is important to work with big data because organizations can collect so much information. As a data engineer, you must write scripts to automate repetitive tasks.
Data analytics and business intelligence systems: You will implement operational system data flows.
Machine learning: Nowadays, Machine Learning (ML) is a hot skill. To become a data engineer, you must possess this skill to understand the basic concepts better in order to understand the needs of data scientists on your team.
Big data tools: A data engineer doesn't work with regular data and manages big data daily. However, they utilize tools and technologies like Hadoop, MongoDB, and Kafka.
Data security: Data security is also an important chapter when it comes to becoming a data engineer. In some companies, there may be dedicated data security teams, but data engineers also need to manage and store data securely.
Presenting findings to non-technical audiences: As a data engineer, you must be able to describe what you are designing or fixing and why it will benefit the organization.
Earn certifications: One of the most suitable ways to become a successful data engineer is to earn the relevant certification programs. The next section teaches you about the best data engineer certifications.
