What is Data Engineering and How to Become a Data Engineer?

Data engineering is an aspect of data science to design and develop information systems.
A data engineer finds trends in data sets and develops algorithms to make raw data more useful for the enterprise.
A data engineer understands how to apply the latest (NoSQL) database technologies and data analytics tools to manage unstructured data sets and solve big data problems.
Data engineers can work closely with data architects and data scientists.

What is Data Engineering and How to Become a Data Engineer?


What is Data Engineering?

Data engineering is the aspect of data science and a software engineering approach that focuses on practical applications of data collection and analysis to design and develop information systems.

There are some mechanisms for collecting and validating large sets of information.
Data engineering helps operationalize engineering practices such as cloud-native applications and big data analytics.

In data engineering, the use of data architecture with compiled files using computer-assisted translation (CAT) tools is essential for preparing from the regular layout and designs for source files.

The scope of the data engineering department includes terminology extraction, image extraction, text extraction, theme change, and programming of custom utilities to meet specific needs.


What Does a Data Engineer Do?

Data engineers are typically software engineers responsible for finding trends in data sets, constructing and maintaining architectures such as databases and large-scale processing systems and developing algorithms to make raw data more useful for the enterprise.

Data engineers install database systems, scale multiple machines, write complex queries, and apply disaster recovery procedures.

A data engineer understands how to apply the latest (NoSQL) database technologies and data analytics tools to manage unstructured data sets and solve big data problems.

A data engineer builds large-scale data processing systems and develops innovative big data solutions.

Data engineers use modern software delivery practices to facilitate monitoring, alerting, continuous integration, continuous deployment; security compliance and other scenarios that help improve software agility and quality.

Key Responsibilities of Data Engineers
The role and responsibilities of a data engineer may include:

–Developing data set processes for data modeling, mining, and production.
–Making sure systems meet industry practices and business requirements.
–Finding trends in data sets and opportunities for data acquisition and new uses for existing data.
–Designing high-performance predictive models, algorithms, prototypes, and proof of concepts.
–Installing, testing and maintaining highly scalable data management systems.
–Integrating new data management technologies and software engineering tools into existing structures.
–Creating custom software components and analytics applications.
–Employing a variety of languages and tools to marry systems together.
–Collaborating with data architects, data scientists and IT team members on project goals.
–Installing and updating disaster recovery systems.
–Recommending ways to improve data reliability, efficiency, and quality.



How to Become a Data Engineer?

If you want to become an experienced data engineer, you must be passionate about data and building data systems. 

Always remember that engineering is more than data, coding, configurations, and infrastructure.
Enjoy close collaboration with others (users and team members) to create better solutions.

You can adopt practices and principles such as DevOps, Agile and TDD when creating highly accessible data systems.

The heart of the product is open data, which we collect from a wide range of sources. The customers expect the data to be up-to-date, accurate and intelligently integrated into the platform.

Develop cloud-based ETL and data storage systems using batch or stream processing to accommodate data.

Datasets typically contain 1-30 million items. In some cases, this is nice and clean at the point you receive, but in others, you must use a combination of machine-learning algorithms and manual craftsmanship to extract metadata from plain text or pdf files.

Most of the data is geospatial, so you must focus a lot on precise geocoding data and joining across geospatial data sets.

What Skills Do You Need to Become a Data Engineer?
If you want to become a data engineer, you will need to have a  background in mathematics, statistics, computer science, engineering, or have a degree in any field related to Information technology (IT).

Here are a couple of core data engineering skills and resources needed from data engineers.

Building and designing large-scale applications.
Data warehouse architecture and ETL tools.
Database architecture, data modeling and mining.
Distributed computing and splitting algorithms to yield predictive accuracy.
Statistical modeling and regression analysis.
Hadoop based Analytics  (Hbase, Hive, MapReduce, Pig, etc).
The knowledge of coding and proficiency in languages, especially Python, C/C++, R, SAS, Ruby Perl, Java, Golang, MatLab or other such languages.
In-depth knowledge of SQL, as well as Cassandra, and Bigtable.
Hadoop-based analytics, such as HBase, Hive, Pig, and MapReduce.
The knowledge of UNIX, Linux, Solaris or Mac OS and various operating systems.
Six Steps to Launching a Successful Data Engineering Career
Here are 6 essential tips and basic steps for people starting a career in data engineering:

Step 1: Earn your undergraduate degree and begin working on projects.
Step 2: Fine-tune your computer engineering, data analysis, and big data skills.
Step 3: Gain your first entry-level job experience.
Step 4: Get your first job successfully as a data engineer.
Step 5: Obtain additional professional engineering or big data certifications.
Step 6: Pursue higher education degrees in computer science, applied mathematics, engineering, physics or IT related fields.
